New Technology for Flex Printed Circuit – Components under Coverlay

Posted on by Peter

With the development of modern industry, there are more and more projects need to use flexible circuit, and the requirements of assembly are getting higher and higher.

In the Flex Printed Circuit (FPC) typical production process, normally we will finish the entire flexible PCB production process, and then arrange to solder components. But such a finished product, components exposed, it can not pass the waterproof test. Our traditional waterproof process is to cover Silicon or conformal coating.

But how can you make the components waterproof more fastness after flex circuit assembly?

Our engineers decided to change the production process after discussion. For new technology,

  • The first step is trace Etching;
  • Second step is surface treatment (normally is ENIG (Electroless Nickel/Immersion Gold);
  • Third step is component assembling;

  • The Forth step and the most important step is making the pure adhesive between base material and coverlay, we need to laser cutting or punching the cutout above the area of component, so that there’s no extra adhesive in that area and then the total thickness of that area will no be too high.

And you can see the full picture showing step 3 to step 4 of flex circuit components making.

After that, we put the Polyimide on pure adhesive and then go the next step of lamination process. (To laminate the coverlay on the surface of component.).

You can see below pictures.

Best Technology Team Back to Office on Feb 5th

Posted on by Peter

Hello Everybody! We had backed to office on Feb 5! (The ninth day of first month of Chinese Lunar Calendar)

It’s a lucky and sunny day! We had 12 people backed to office (excludes people in factory) and according to Chinese culture, number 12 means every month will be lucky and full of successful!

Today one more girl back, tomorrow another guy will back. It’s a normal thing people didn’t back to office on the first day because there’re always something unexpected, such as Wedding, etc. In 2017, we had saw the new baby born of Tiffany’s, wedding party of Hanna, and this year we will see more baby and wedding.

Everybody was so happy to see each other after 2 weeks Spring Festival and eat the wedding candies, as well as checking and replying emails. We have a simple and colorful lunch together and in the afternoon went to Phoenix Mountain Forest for hiking. This is a traditional activity on the first working day after New Year vacation in our company. We can talk to each other under the open air, everybody shared their stories and we always laugh when heard something interested happened during holiday.

Differences between Roll Anneal Copper Foil and Electrolysis Deposition Copper Foil

Differences between Roll Anneal Copper Foil and Electrolysis Deposition Copper Foil

Roll Anneal Copper Foil (RA copper):

Formation: Roll copper block many times, and then do the annealing treatment with high temperature. The shape of its crystal is lamellar structure.
Advantage: Soft, smooth surface, suitable for flexible PCB and small lines.
Shortage: high cost

Electrolysis Deposition Copper Foil (ED copper):

Formation: Melt copper into dilute sulfuric acid, it becomes bluestone solution.
Through a high electric field, copper attach on the metal drum. With the rolling of metal drum, thin copper foil finally formed.

Advantage: Low cost
Shortage: Unsuitable for small lines; bad bending resistance.
Here is the cross section observation of RA Copper and ED Copper:
