Today we are going to discuss the solderability test experiment. In order to explain it more clear, we now do a simple solderability test and show you all the steps.

1. Take a small solder pot, plug in the power, turn on the switch and heat the solder pot to a certain high temperature(about 8 minutes).

2. Put a tin bar to the solder pot, then you can see the tin bar is begin to melting, slowly into liquid tin, then more and more.
3. After few minutes, there will be enough melting liquid tin in the solder pot to do this test.
4.Use a tweezers to pick up a PCB circuit, first clean the PCB with rubbing alcohol. Because the unclear surface or the oxidation of the PCB will affect the test result.
5. This is the key step of this test, put the PCB into the solder pot, depth about 2 mm,time 4-5 seconds is ok. Then you can see the tin will go into the hole of the PCB.
6. Take out the PCB from the solder pot and put it into the cold water. After few seconds, you can see the experimental effect.

This solderability test is very simple and easy. We can see the results very soon. Our Best Technology did solderability of every batch PCB we made, and we also supply our customers with the solderability test report and the test samples.

The National Day of the China is celebrated every year on October 1. It is a public holiday in China. Usually people will have a 7 days holiday to celebrate the national day, called “Golden Week”.

National Days are festivals which can stand for independent countries. In the world, countries establish their Notional days on the basis of different ways. Therefore, the names and celebrations of National days in different countries are various. In China, The most significative activity in National Day is The Big Parade in Beijing, Parade Is a ceremony to review the armed forces.

This day is a day of national celebration. Most people will go travel on this holiday, especially to visit the “Red” tourist sites. People also can enjoy kinds of evening party.

On this national day of prayer and remembrance, we ask almighty God to watch over our nation, and grant us patience and happyness!

Our Best Technology will have a 4 days holiday from tomorrow (Oct 1) to Oct 4 to celebrate the National Day, and reopen on Oct 5. Hope everyone can enjoy this holiday and have a good rest.

Happy National Day! Best Wishes To Our Great Motherland May our country become prosperous and strong!

Mid-autumn Day is one of the import traditional Chinese festivals, falls on the fifteenth day of the eighth lunar month. On that night the moon is brighter and fuller than any other night. In China, Mid-autumn Day is a time for family reunions.

In ancient China, poets considered the moon as a symbol of brightness, purity, and goodness. They wrote many beautiful poems about the moon. The most popular one was a story about a lady on the moon. She flew to the moon and lived in the Moon Palace.

On Mid-autumn Day, almost everyone gets together with his or her family, eating mooncakes, chatting and watching the moon. Mooncake, whose round shape symbolizes both the fullness of the moon and family togetherness. There are many kinds of mooncakes. They are small round cakes with meat， nuts or something sweet inside . eating mooncakes has been our custom.

The Moon Festivals is one of three major Chinese holidays, along with the Spring and Dragon Boat Festival .On that day， families get together，so we call this day getting together. This is Mid-autumn Day. I love it very much.

Our Best Technology we will have a three day holiday(from Sep 10 to Sep 12) to celebrate the Mid-autumn Day and will reopen on Sep 13. Best Technology wish you all have a happy Mid-Autumn festival! Enjoy the beautiful life together with your family forever.

The Tomb Sweeping Day in Ancient Times
In ancient times, people celebrated Qing Ming Jie with dancing, singing, picnics, and kite flying. Colored boiled eggs would be broken to symbolize the opening of life. In the capital, the Emperor would plant trees on the palace grounds to celebrate the renewing nature of spring. In the villages, young men and women would court each other.

The Tomb Sweeping Day as Celebrated Today With the passing of time, this celebration became a day to honor the past ancestors. Following folk religion, the Chinese people believed that the spirits of deceased ancestors looked after their family, sacrifices of food and “paper money” could keep them happy, then they would bless the family prosper through good harvests and have more children.
Today, Chinese visit their family graves to tend to any underbrush that has grown, remove the weeds, swept away the dirt, and set out offerings of foods and burning “paper money”.

Up to now, the custom of obeisance ancestry and grieve over those already died relatives on Tomb Sweeping Day are still very widely accepted.

Out Best Technology will have our Tomb Sweeping day holiday from today till Apr 5. And back on Apr 6. Hope everybody have a nice weekend and enjoy life better.

The substantial price rise of the copper foil directly influences the CCL and PCB industry. In February, both the thick and thin CCL had raised 5%-8%. Fiberglass had risen 20%. The PCB industry have gradually turned the corner also had to rise in price. The PCB industry improved obviously in the first quarter this year since last year’s downturn. The price of fiberglass appears a rose space .

On the side, the RMB appreciate against USD dollar, furthermore, gold and copper price, still keep rising since late last year. Especially CCL have also rised this year, this made PCB manufacturers under much pressure, more than 10% of the products had been raised the prices. Some few manufacturers are still keep communicating with their customers recently.

I think people can find the answers in help center of Paypal but seemed people like to see the process in pictures. As preverb says: A picture worths thousands of words. So I wrote this artcile and hope this will help people understand it.

A) Send Money to Paypal A/C

Send money to your customers, your friends is very easily. Login your A/C and click “Send Money” on top position and you will see two opinions: “Send money online” and “Pay for eBay items”. I take a picture showing “send money online”.

Just input the A/C No. (Actually it’s an Email address), amount of money and purpose of this fund, and click “Continue”. You will see a new page to confirm the A/C No, amount:

You can also write a message to receipt, limited to 300 characters.

After checking everything is right, then confirm it and money will be sent out.

Very easily? Yeah! Next time let me show how to receive the fund your customers or friends send to you.

I think you’ll like it, Paypal is very convenient for small amount of money transfering, very fast (almost immediately), free to send money, and a little receiving fee (most of time, none).

So my friend, if you order flex circuit, rigid-flex, or any circuit boards, with our company (Best Technology), small amount (less than $500), you can choose this way.

All right. Is everything clear for you now? Any question, write email or leave message here, we will answer it very fast.

The festival is best known for its dragon-boat races, especially in the southern provinces where there are many rivers and lakes. This regatta commemorates the death of Qu Yuan , an honest minister who is said to have committed suicide by drowning himself in a river.

Qu Yuan

The people of Chu who mourned the death of Qu threw rice into the river to feed his ghost every year on the fifth day of the fifth month. But one year, the spirit of Qu appeared and told the mourners that a huge reptile in the river had stolen the rice. The spirit then advised them to wrap the rice in silk and bind it with five different-colored threads before tossing it into the river.

During the Duanwu Festival, a glutinous rice pudding called zong zi is eaten to symbolize the rice offerings to Qu. Ingredients such as beans, lotus seeds , chestnuts , pork fat and the golden yolk of a salted duck egg are often added to the glutinous rice. The pudding is then wrapped with bamboo leaves, bound with a kind of raffia and boiled in salt water for hours.

The dragon-boat races symbolize the many attempts to rescue and recover Qu’s body. A typical dragon boat ranges from 50-100 feet in length, with a beam of about 5.5 feet, accommodating two paddlers seated side by side. Dragon boat races in long, thin, canoe-like boats often sporting the head of a dragon on the prow, are a southern Chinese tradition.

Zongzi

Except eating zong zi and dragon-boat races Chinese people also cleaning the house on that day. The Dragon Boat Festival is also a cleaning festival. It is traditional for people to clean their houses on this day. It is also considered important to put up some leaves of mugwort or cattail on either side of the door, spray realgar water, and drink realgar liquor. These things are thought to prevent rot and kill bacteria to stop the spread of diseases.

Experts say, the Dragon Boat Festival custom began in China, the spring and autumn and warring states period, has more than 2000 years of history. But today, Dragon Boat Festival is still a very popular and grand festival among Chinese people.

                                  The basic definition of via

As is known to all, via is one of the important parts of multilayer PCB. The cost of drilling usually makes up 30%~40% of the cost of PCB manufacture.

Simply speaking, every hole on PCB may be called via.

Functionally, via can be divided into two types: firstly, used for electro-connection among layers; secondly, used for fixing components.

Technically, it may also be divided into three types: blind via, buried via and though hole. Blind via is located on the top and bottom surfaces of the PCB, deep and used for connection of top traces with the inner layer traces below.

Buried via is the connecting hole which is located in the inner layer of the PCB and won’t extent to the surface.

Through hole goes through the whole PCB, which is used to realize inter-connection or used as components mounting position hole. Due to the simple technique and low cost, most of PCBs use it rather than the other two via.

3. Components encapsulation technology

(1) Through hole technology

It means we mount components on one side, and solder the pins on the other. The disadvantage of it is space consuming. In fact, theirs pins take up space of both sides. While the advantage of it is good construction, which can bear pressure.

(2) Surface mounted technology
it means pins are soldered on the same side as components. We don’t have to drill holes  on PCB and don’t have to solder every pin. The advantage of SMT is that the components are more compact and cheaper than those in THT.

4. Gerber files:

Usually it comprises the layout plan of signal, ground, power, solder mask, silk screen, and drilling layout plan, etc.

5. Manufacture steps
choose base material, then use subtractive transfer to show the artwork on metal conductor.

The above explanation is only the most basic   information, if you want to know more, please to go our website: http://bestpcbs.com/products or contact me at Iris@bestfpc.com.

We are happy to help you clear all your questions!!!

 (1) Single sided PCB

Single sided board means the conductor pattern appears only on one side. Because single sided PCB has many strict limits. On trace design, only circuit at early stage use this kind of boards.

(2) Double sided PCB 

Double sided board means the conductor patterns appear on both sides of the board. However if we use the conductor patterns on both sides, there should be proper circuit to connect two sides. The bridge between the circuits is called via. Those vias are plated with metal, such as tin, copper, gold, etc. Because the area of double sided PCB is two fold of the area of single sided, and the conductor pattern can cross with each other, so it suits to be used on more complex circuits.

(3) Multi-layer boards

In order to enlarge the area of conductor pattern, multilayer PCB uses more single or double boards. It uses several piece of double sided boards, and a dielectric layer is put between every layer of boards. The layers of one PCB represent the layer of conductor patterns. The amount of the layers is always even number. Technically we can make PCBs up to 100 layers.

 For via, if we use it on double sided PCB, the whole boards will be drilled. While on multilayer PCB, if you just want to connect some traces, via may will waste trace space of some layers. Then we use buried vias and blind vias to solve this problem, because they are only drilled through several layers.

a. Buried vias only connect inner PCBs, so we can’t see them from the surface.

b. Blind vias connects several layers PCB with surface PCB.

In multilayer PCB, the whole board directly connects the ground line and power (used for preventing affection of the transmission signals on the signal). So we divide layers into signal, power, or ground. If the components on PCB need different power supply, this kind of PCB would have more than two layers of power and wire layers.

1. Definitions:

For standard PCB, it is the combination of bare board and components on it. While for bare board PCB, it is called printed wiring board. We usually call it PWB.

(1) Traces:

The base material of PCB is comprised of dielectric, heat insulation, uneasy to bend materials. On its surface, we can see thin traces, its material is copper. Originally the copper covered the whole PCB. Parts of it were etched during the process of production. Those parts left become net-like thin traces, which are called conductor pattern, and are used to provide circuit connection for components on PCB.

(2) Name of two side:

On most common single sided PCB, components are on one side, conductor pattern is on the other side. Then we would need to drill holes on the board, so that pins can put through the board to the other side. Therefore, the both sides of PCB are called component side and solder side.

(3) Gold finger:

Gold finger is functioned to connect two PCBs. We usually insert the gold finger of one PCB to the proper slot of the other PCB. 

(4) Solder mask and silk screen:

The green or white oil on PCB is called solder mask, which is functioned as dielectric protective layer, can protects copper traces and also can prevent components to be soldered at incorrect place.

On the dielectric layer, a layer of silk screen will be printed. Some words will be printed to show the position of those components. It is also called legend.

 Industry research institute Shuiqingmuhua published “global and China circuit board industry research report of 2009”. The FPC industry emerged in 2002, developed very quickly in 2003 and 2004, and went into the stage of price struggle. In 2006 and 2007 the FPC industry has been in downturn, however in 2008 it began to recover. Even the economy crisis didn’t get in the way of the recovery of FPC industry. On one hand, the price reduction stimulates the demand of FPC; on the other hand, the demand for lighter, thinner, shorter, smaller and high reliability products also creates the room of using FPC. At the same time, the FPC manufacturers which went through price struggle and survived had all faced great pressure. They have already been familiar with the cost control and dealing with stress, and won’t be afraid of the arrival of economy crisis. Cell phone is the critical motive for FPC market enlargement, especially intelligent cell phone and high-end cell phone. The growth of consumer electronics field is also favorable. In consumer electronics such as notebooks, PND, digital camera, DV, LCD TV, plasma TV, media player, frequency of using FPC will increase as its performance and its strive for ultra-thin volume. Notebook and flat panel TV use LED backlights a lot. FPC is the most common used way in which LED connects to the main circuit. Even in 2008 and 2009 it still has great potential to grow. The swing joint between notebook screen and motherboard has great probability of using FPC. (Continued)

Now I want to introduce the basic method of calculating the thickness of FPCs.

(!) single sided FPC

The constructure of single layer FPC is as follows:

25um+20um+35um+20um+25um=125um≈0.12mm

Note: the thickness of adhesive changes according to the thickness of Cu. For 1/2, 1/3 OZ Cu, we usually use 12um adhesive. But for 1OZ Cu, we have to use 20um adhesive.

That’s according to the common material. If we want the board to be thinner, we also can use the adhesiveless material to make the board about 0.8mm thick.

(2) double sided FPC

Double sided FPC means there are two layer of traces in the FPC.

The constructure of double sided FPC is as follows:

25+12+35+12+25+12+35+12+25=193um≈0.20mm

1. Original cost is high

Because the FPC is designed and made for special application, the cost of circuit design, wiring and photographic plate is high. Except special need, we’d better not use them.

2. The modification and correction is difficult

Once FPCs are made, if we want to modify, we have to begin from the base drawing or gerber program. Therefore it’s difficult to change. On its surface there is a coverlay. Before the modification, we have to remove it, after the modification, we have to recover it, which is difficult.

3. Dimension limitation

Since FPC is not popular, we usually use intermittent method to make them. Then we can’t make too long or wide FPC with the limit of manufacture instruments dimensions.

4. Easier to be damaged if improper operation

It is easier to cause the damage of FPC circuits because of improper operation. Special trained workers are needed in tin plating and rework

 B: Advantages

FPC is the printed circuit board which is made of flexible insulating base material. It has many advantages many rigid PCBs don’t have.

1. It can be bent, rolled, folded freely, can be arranged randomly according to the space, can be moved and stretched in 3-D space, then integrate the components assembly and wiring connection.

2. It can satisfy the need of electronic products to develop in the direction of high density, smaller size, higher reliability, since FPC can greatly reduce the volume and weight of electronic products. Therefore FPC is widely applied in fields or products of aerospace, military, mobile communication, laptop, computer exterior design, PDA, and digital camera.

3. FPC also has the advantages of good thermal diffusivity and solderability, easy to assembly, low combined cost. The design of rigid-flex boards also make up the disadvantage of components carrying ability of flexible base material.

 The second most important is LCD. LCD is divided into categories such as TN, STN and TFT. TN type LCD is applied in black and white display products, such as calculators and electronic watches; STN is mainly applied in colorful display products; TFT is mainly applied in medium-big flat panel display, such as notebooks, LCD Monitor, LCD TV. Due to the stable growth of those consumer products in recent years, FPC also grows stably. Its market and manufacture is mainly distributed in Japan. The combined growth rate of the IC substrate market in 2001~2006 promotes the corresponding growth of FPC.

 This index is the highest since November in 2008. However, compared with the same time last year, it is reduced by 1/8. The orders in July, 2009 are unexpected good, which is increased by 22% than in June, even 2.5% higher than in July 2008. Regarding the first seven months this year, this number only reaches the half of the level at the same time last year.

 Before punching the outline of flexible printed circuit boards, firstly stick the FPC on the polyester supporting spring printed with adhesives, using knife mold to cut the outline, and then send to our clients. The clients can get the flexible printed circuit boards and do the assembly, or they can do the assembly at first, take them from the polyester supporting spring after finishing the assembly. This method can be only applied on the products with small dimensions. Which can greatly improve the operation efficiency  whatever to flexible printed circuit boards manufacturers or to clients.

 The safest way is to use special tray, at first we prepare the trays according to the FPC types. Although the management is complex, the quality is guaranteed. They are convenient to use and helpful for client assembly, low cost and can be thrown away thereafter.

 According to the layer of conductive copper, FPC is divided into single layer, double layer, multilayer, dual access, etc.

 The structure of single layer: the most simple. Base material + transparent adhesive + copper is one set of the raw material; coverlay + adhesive is another. Firstly, the copper needs to be etched to get the traces, while the coverlay needs to be drilled to expose corresponding soldering pad. After cleansing treatment two set of raw material are bonding together by rolling. Immersion gold or tin is done on the exposed soldering pads to protect from oxidization. At last, FPC is punched into smaller ones of corresponding shape.

 Some FPC doesn’t use coverlay but prints solder mask on the copper directly, which lowers the cost, but worsens the mechanical strength of FPC. Using coverlay is the best, unless at the occasion of low mechanical strength and the lower price the better,

 The structure of double layer FPC: when the circuits are too complicated, the single layer FPC can’t or needs copper to do ground shield, double layer even multilayer FPC is needed.

 The most typical difference between multilayer and single layer FPC is that the multilayer FPC is added with through-hole structure to connect the copper on every layer. The first workmanship of base material + transparent adhesive + copper is to make through holes. Holes are drilled o the base material and copper, after cleansing treatment they are plated with a certain thickness of Cu, then the through hole is done. We call it PTH (plated through hole). The technique after is almost the same with single layer FPC.

 The structure of dual access FPC: dual access FPC has soldering pads on its two sides, mainly used to connect with other circuit boards. Although it has similar structure with single layer FPC, its technique has great difference. Its raw material is base material + adhesive + copper, coverlay + adhesive. Holes are drilled on the coverlay according to soldering pads location, then stuck on the copper. After etching the soldering pads and traces another coverlay with drilled holes is stuck on that.

 2. The performance and selecting method of the materials

 (1) Base material:

 PI (Polyimide) is the most common used, which is a kind of macromolecule material of high temperature proof and high strength, invented by Dupont. The polyimide made by Dupont is called Kapton. Besides some polyimide made in Japan can also be found. Its price is much lower.

 Polyimide can bear 10 seconds of high temperature of 400 degree centigrade. Its tensile strength is 15,000~30,000 PSI.

 The base material with 25um thickness is the cheapest and the most popular one. If we need the circuit board to be more rigid, we should choose 50um. Otherwise, if we need the circuit boards to be more flexible, then choose 13um.

 (2) Adhesive:

 It is divided into epoxy resin and polyethylene, they are all thermosetting adhesive. The polyethylene’s strength is lower. If we hope the circuit boards to be more flexible, then choose polyethylene. The thicker the base material and the adhesive on it is , the more rigid the circuit boards are. If the circuit boards have to be bent in a large area, we should choose thinner base material and adhesive so as to reduce the stress on the surface of the copper, then lower appearance of micro crack.

 (3) Copper:

It is divided into rolled annealed copper foil and electrodeposited cooper foil. Rolled annealed copper foil is of high strength and can stand bending, but its price is higher. Electrodeposited copper foil is much cheaper, but of low strength, easier to be bent.

When we choose to use rolled annealed copper foil, we should pay attention to the direction of the copper. The direction of the copper has to be the same with the bending direction of the circuit boards.

 (4) Coverlay and its adhesive:

 25um coverlay would make the circuit board more rigid, but it is cheaper. Therefore to the circuit board needing to be bent greatly, we’d better choose 13um coverlay.

 The adhesive is also divided into epoxy resin and polyethylene. The FPC using epoxy is more rigid. After thermosetting, there are some adhesive squeezed out at the edge of the coverlay. If the soldering pads are larger than the hole on the coverlay, the adhesive squeeze out would reduce the size of the soldering pads and lead to irregular edge. Therefore, we’d better choose 13um adhesive.

• 十月 13, 2009 -- The advantage of using FPC

 According to the combination ways of the base material and the copper, the FPCs can be divided into two kinds: adhesive FPC and adhesiveless FPC.

 The price of adhesiveless FPC is much higher than the adhesive FPC. However it is superior to FPC in the aspects of flexibility, boning force of copper and the base material, and the flatness of soldering pad. Therefore generally it only is used in the occasion of high demand, such as COF (chip on flex, to mount exposed chips on FPC has high requirement of the soldering pad flatness).

 Due to adhesiveless FPC’s high price, at present most of the FPCs applied at the market are adhesive.

 Because the FPC is mainly used at the occasion of bending, if the design or technique is not proper, defaults such as micro-crack, snap of the welding point will be easy to arise. I will introduce the structure of FPC and its special requirements on design and technique.

 The flexible circuit boards are to etch the copper traces on the polymer base material, or to print polymer heavy layer circuit. In regard to thin, light, tightly and complicated structured components, their design scheme comprises from single sided conductive circuit to complex multilayer 3-D packing. The overall quality and volume of flexible packing decreases by 70% than using the traditional mega wire thread method. The flexible circuit can also increase its strength by using supporting material or lining board, so as to obtain extra mechanical stability.

 The flexible circuits can be moved, bent, twisted, without ruining the traces. They are with different shapes and special packing dimensions. The only limit is the problem of room and volume. Due to being able to bear millions of dynamic bending, the flexible circuits can be well applied in the inner connection system of continuous movement or regular movement, becoming one part of the final product function. Some products demanding for smaller shape modulus/packing dimensions because of the movement of electrical signal/power all benefit from the flexible circuits.

 The flexible circuit provides good electrical performance. Lower dielectric constant allows electrical signals to transmit quickly. Good thermal performance makes the assembly easy to cool. Higher glass transfer temperature or melting point makes the assembly work well at higher temperature.

 Because the quantity of the hardware needed for inner connection is reduced, such as the welding pots、trunk lines, base board traces and cables usually used in traditional electric packing, the flexible circuits can provide with higher installation reliability and yield. When the traditional inner connection hardware comprised of many complicated systems is mounted, higher rate of assembly out of alignment happens easier. As the emergence of quality engineering, a very thin flexible system is designed to be mounted in only one way, so as to eliminate the human error related to independent wiring installation。

 At early stage the flexible circuits are mainly applied in the fields such as the connection between the small or thin electronic products and rigid printed boards. In the end of 1970s, they were used in the electrical products such as computers, digital cameras, ink jet printers, car audio, CD-ROM and hard disk driver. Opening one 35mm camera, there are 9~14 different flexible circuits. The only way to decrease volume is smaller assembly, more precise lines, tighter spacing, and bendable objects. Heart maker, medical instruments, video camera, hearing aid, laptops, all most all the products we use comprise of flexible circuits today.

Because the prices of NB fall year after year, and people’s demand for PC mobility increases constantly, the tendency that NB will replace the desktop computer becomes more and more obvious. Some brokers in Taiwan expect that the worldwide turnout of NB in 2009 will be 131 million sets, increasing by 3.7% than that in 2008. Considering the additional demand for low cost NB, they estimate that the turnout of whole NB will reach 155 million sets. Annual growth rate will reach 12.58%. This growth prediction is rarely seen recently. Therefore it’s unnecessary for the NB board manufacturers to worry about. The NB turnout of Hann Star board and Gold Circuit Electronics in 2008 will increase 7% and word wide market share will rise from 63% (in 2007) to 70% which will make NB market a duopoly and there is nearly impossible for a new company entering into.

Besides, the market generally believes that the overall mobile phone demand in 2009 will decline. For intelligent mobile phones which use lot of FPC, however, the turnout in 2009 is estimated to be 186 million sets. The annual growth rate is still as high as 18.1%, which becomes the largest growth power for Taiwan FPC industry. As for the aspect of supply, because of the fierce competition, many second-tier FPC factories became bankrupt, which will be helpful to keep the  stability of FPC industry.

One end of FPC will be inserted into the connection area of LCD and the others will be connected with other input or output machines. The major function is to transfer data smoothly and safetly.

LCD Mould FPC bottom view

As quantiyt of LCD is related big, so the quantyt for this kind of FPC will also have a certain quantity. So people should be very careful in designing and manufacturing, because normally the L/S and L/W is small, about 3~4 mil. Without suitable manufacturing artwork and technology, the yield will be very low.

We have much experience on making LCD flex circuits, knowing what’s the keystone, what kind of problems maybe happened owing to its own charactericstic, how to avoid it and how to make FPC in great condition.

1) The whole Flex circuit is the repeated of several section of FPC.

So we can populate LEDs, as well as ICs, etc, on FPC. And then solder each sections together, strip-by-strip, to make a long flex circuit boards. 

led-flex-circuit-solder-together on a roll

After several strip of FPC is connected by soldering, or using connector, we will do testing and then packing them in a roll, normally 3 meter, or 5 meter. It should be packing in vacuum packing. 

  2) Just make the enough length single FPC one time, without the soldering connecting.

 This is used in some special end-products which obvious soldering is prohibitted and more strength is needed. Of course, this kind of FPC is more difficult to make, becuase of manufacuturing artwork & equipment limited.

LED FPC

In fact, this Flexible circuit with LED is a special single sided fpc or two layers FPC, with adhesive tape at the bottom side, easy peel off and installation. The outstanding characteristic is its length. Theoretically, the length of this Flexible circuit can be made according to clients’ request.

The popular maximum length currently used, however, is about 8-10 meter (2.5-3.0 ft), because of power and thermolysis limited.  (Please browse our site for more: http://www.bestfpc.com/products/single-sided-fpc.htm, http://www.bestfpc.com/products/double-sided-fpc.htm).

Here we’d like to talk about some features of Flexible Circuits with LED & LED Flexible Circuits

1) Separable SMD/SMT LED strip on Flexible circuit boards can be bended to the tour of any products with self adhesive tape back, easy installation! They are mounted on self-adhesive tape and can be conveniently field-cut. For adhesive tape, normally we use 3M 467/946/966, or as per request.

2) As long as the clients request (strip-to-strip soldered connecting). You can also choose our extreme long FPC which is 9.8 feet (3m) without soldering.

3) This flex circuit modules, after LED SMT/SMD were done, are ideal for edge lighting transparent and diffuse material. They provide an optimal solution for precise backlighting of complex contours. They can also be used of lifesaving/rescue sign lights and commercial signs and for making contours like escape routes, borders and stairs.

4) Customer design LED location, quantity, color (red, green, blue, true green, white (phosphor on blue), yellow, etc), according to the request of luminous intensity & color.

5) Flexible circuit boards (FPC) surface in white finish, with classic looking, or as per request

6). With IC constant current circuits, guarantee stable working current and even light output for the whole reel of lights.

In next article, we will discuss the way/method to make this type of LED Flexible circuit)

China Ministry of Finance said Tuesday that, starting July 1, the country would cut or eliminate export tax rebates for 2,831 commodities representing 37 percent of the total number of items listed on customs tax regulations.

A ministry spokesman said the move was one of a basket of measures to suppress overheated export growth and ease frictions between China and its trade partners.

The country will abolish export tax rebates on 553 highly polluting products that consume heavy amounts of energy and resources such as salt, cement, and liquefied petroleum gas, said the spokesman.

Tax rebate on exports of 2,268 commodities which “tend to cause trade frictions” will be reduced, he said.

The country will scrap the export tax for ten commodities including shelled peanuts, canvas, wood for carving and stamps, according to the spokesman.

The new tax rebate system will have five levels, namely 17 percent, 13 percent, 11 percent, 9 percent and 5 percent.

The spokesman said the cost of producing the 2,831 commodities would increase as a result of the changes to the export tax rebate regime. This would incite capital investment to move to other “high value-added and high tech” industries.

In the long run, this would help the country develop in an economic and sustainable way, he said.

Customs statistics show that from January to May, the country reported a trade surplus of 86 billion U.S. dollars, up 83 percent on the corresponding period of last year.

Soaring exports have increased liquidity in the domestic market and added to pressures on the RMB, said experts.

After several weeks work, the new website of Flexible Circuits is finished right now, before the National Day. There’re, however, some things still need careful modify in future. You’re higly welcomed to leave your comments on it. 

Tomorrow is Oct 1st, the National Day, we’ll have a short vacation to celebrate that special day. When come back, I think I should pay much attention upon the information about the Flexible Circuits. As the proverb says: “It’s never too late to learn!”
