Happy Mid-autumn Day!

Posted on September 10, 2011September 10, 2011 by Lucy

Time flies! Now we ushered in the 2011 Mid-Autumn festival.

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.

Tomb-sweeping Day

Posted on April 2, 2011 by Lucy

Tomb Sweeping Day is one of the few traditional Chinese holidays that follows the solar calendar– typically falling on April 4, 5, or 6. Its Chinese name is “Qing Ming” literally means “Clear Brightness,” hinting at its importance as a celebration of Spring. Similar to the spring festivals of other cultures, Tomb Sweeping Day celebrates the rebirth of nature, while marking the beginning of the planting season and other outdoor activities.

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.

Solderability Test

Posted on March 29, 2011 by Lucy

Solderability testing has become more common in the industry particularly to assess components and printed board surface finishes during the transition to lead-free manufacture. The wetting balance is the standard method of test and provides the repeatability that other methods do not.

Test Principle: Put the samples into tin bath, detect the solderability according to the hole wetting degree.
Ttest Purpose: Test the solderability of the PCB samples
Test Instrument: Thermostatic tin stove

Procedure:
1. Setting the tin slot temperature at 245℃, turn on the power.
2.Waiting for the Test Procedure up to 245℃+/-5℃, paint the samples with rosin. Use clamps nip it , just do as wave-soldering,let samples contact with the tin slot surface. Depth is about 2mm, time is nearly 4 seconds.
3. Tin material changing times: once / two weeks
4.Comments: The plated holes permit only 10% with half infiltrating, nonwettable and air blow is not allowed.

Figure 1. PCB samples before testing with the wetting balance

Figure 2. PCB samples after testing with the wetting balance.

As assembly Electronic components to printed circuit board always need high quality Interchange connection technology, doing the solderability test has great help to the high quality and zero defects welding technology. Our Best Technology did Solderability Test for every batch PCB, but due to some objective reasons, we didn’t give customers the solderability test samples. If customers need it, can also contact us.

Express our deep sympathy for Japanese and May God Bless them!

The PCB raw material rise in price

Posted on February 28, 2011 by Lucy

International copper prices surged in the latter part of last year,this directly impact the price of copper foil. Since last September it raised month by month. It is reported that February is still raising 8% to 10%, and don’t eliminate to reset to higher prices again in March.

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.

Dragon Boat Festival

Posted on June 15, 2010June 15, 2010 by Peter

The Dragon Boat Festival, also called the Double Fifth Festival, is celebrated on the fifth day of the fifth month according to the Chinese calendar. For thousands of years, the festival has been marked by eating zong zi (glutinous rice wrapped to form a pyramid using bamboo or reed leaves )and racing dragon boats.

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 knowledge of printed circuit board via

Posted on March 5, 2010March 5, 2010 by Lucy

via

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.
