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.

Cutting -> NC Drilling -> Black Holes/Cu Plating -> D/F Lamination -> LDI Exposure ->Develop/Etch/Stripping -> Automatic Optical -> CVL Lay UP -> CVL Lamination -> Hole Punching -> Surface Treatment -> Screen Printing -> Open/Short Testing -> Adhere Stiffener -> Outline Punching -> Final Inspection

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:
