New Product–2L FPC Coil Board with Bumped Point

  In September, 2018, in order to provide customers with the most suitable products and the most satisfactory services, Best Technology released a new product—-2L FPC Coil Board with Bumped Point. This product was developed on the basis of the old version. The surface of the old one is flat. For this reason, it will cause poor contact when assemble with a conductive film.  

  Could you tell the difference between the old one and the new one? If not, hoping this article can solve your puzzle.

New Version VS Old Version
Picture1:New Version VS Old Version

  There is an obvious difference—-the new version has bumped point, but the old one is opposite. So what is the advantage of 2L FPC Coil Board with Bumped Point? The new one with bumped point, it will get easier to connect when assemble with a conductive film. Because the shortcoming of the old one, we have improved with advanced technology, adding bumped points in the flex printed board. And it is easier to connect when the pad is attached with the conductive film.

  From the following picture, we can see that the new version is single-sided flexible circuit board with bumped point.

New Technology for Flex Printed Circuit – Components under Coverlay

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

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.

American Customers Visiting us after Mid-Autumn Festival

On Sep 19th, Our America customer Julie and Sonic visited us. The main topics we discussed the flexible circuit board and assembly (PCBA).

Firstly we do a sample introduced for whole FPC production process to Julie and sonic. During our production, we are strictly carry out all the production process conform with ISO9001:2008.

FPC IQC process checking

FPC IQC process checking

From the FPC raw material IQC incoming quality inspection, warehouse material management (first in first out management principle), the standard operating procedure thru production process: from flex circuit board raw material (Polyimide) cutting, drilling, lamination, stiffener/adhesive tape assembling, silkscreen, IC programming, trace & via opening & shorting and function testing, to final flex circuit board out-going inspection.

 

During this period, we are mainly introduced coverlay lamination process for flexible circuit board,

After FPC production line tour, Julie and Sonic advice some comments for their 2 layers flex circuit board which with impedance control design-in.

With their good suggestions, we know how to make improvement for the flexible printed circuit board production process and the documentation control in future flexible board manufacturing.

By this visiting, both Julie and us know much more of each other and believe there’re lot opportunities for flexible circuits in come future.

Customer Luke visit Best Technology

On Aug 25th, Luke from Australia visited us. The main topics discussed were flexible circuit production process, testing and the improvement solutions.

Firstly we introduced FPC production process to Luke, from raw material cutting, drilling, laminate, stiffener/adhesive tape, silkscreen, IC programming, testing, different outline making method (laser cutting for flexible circuit board prototype, Die-punching for flex board volume production).

The most important things were opening & shorting testing for FPC and dimension and cosmetic looking using 2 D measurement machine. After seeing the E-Tester of his 4 layers flex circuit board, Luke known the board will be tested from both top and bottom side at the same time (We put and tested the flexible board top and bottom side on the E-tester, and the connector of FPC contact with the test pins on the E-Tester), and discussed how to avoid incorrect testing, such as missed or wrong testing point. The Tester was made according to customers’ original Gerber file.

By using 2D measurement machine, we found out how break off trace, hole alignment and other issues affected the function of circuit board.

After that, Luke told us his suggestions on how to make improvement for the production yield and testing and we will try these in future flexible board manufacturing.

By this visiting, both Luke and us know much more of each other and believe there’re lot opportunities for flexible circuits in future.

The reason for the problem of development is not clean and has Residual glue in FPC?

How to deal with these situation?

  1.  How to deal with these situation?There have glue mark and greasy dirt on the boards in prepared processing stage, it need to clean the plate thoroughly.
  2. The temperature is too high and time is too long in the stage of Pre-heating, so it need to control the temperature of the pre-drier, adjust it on normal temperature and strengthen the control of time.
  3. The exposure energy is too high on the stage of exposure, or the shading rate is poor of the base boards.
  4. The developing liquid’s concentration and the temperature are too low, so it need to check the concentration and adjust the temperature to normal timing.
