Normal Thickness for 2Layers Flex Circuit (Adhesiveless)

Following up with the last article , here we’d like to share thickness for 2L flex circuit if using adhesiveless material.

2L FPC Flex circuit thickness (adhesiveless)

We also have other special material, such as 1mil Polyimide + 2OZ (70um) copper adhesiveless, (from Dupont). If you need more information, please contact us.

Normal Thickness for 2Layers Flex Circuit (Adhesive)

Different from rigid FR4 PCB, there’re three basic layers for flexible circuits, and various thickness of each maybe used, so people new to that area will be confused to choose a suitable thickness.

Here are four normal thickness for 2 layers (Double sided) flex circuit, and we hope it’ll be useful for the green hand:-)

As you can see, there’re adhesive in base for each four basic thickness of 2L (double sided) flex circuits, if you need more thin, then you can use adhesiveless material, and final thickness will be thinner even you use the same copper and Polyimide thickness. Please see next article (to be continued…)

Earthquake in Japan

When news come in, no one can believe it. I think, is it a rumor? But few hours later, we have to accept the fact. 9.0 Earthquake really happened in Japan! It is one of bigger disaster recently happened in the world. Remember last time in China, the earthquake is only 8, but it has caused uncountable lost for us. We really hope this bad condition will be finished very soon.

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

Happy Chinese Rabbit Year

Send Money Via Paypal

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.

Dragon Boat Festival

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

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.

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.

NB board and FPC: the only hope in 2009 PCB industry

Look into the prospect of 2009 PCB industry, due to the fact that the Notebook (NB) and intelligent mobile phone still have the potentiality to grow, therefore, people in the industry generally believe that there are still hope for the growth of NB board and FPC.

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.
