Flexible Printed Circuit

Bright PCB Technology experienced on prototyping Flex PCB(FPC)

We Bright PCB Technology has years of producing FPC, with our experienced guys serves hunders of clients who need Flexible Circuit Board. Our products including the Single layer FPC, double sided FPC, and multilayer FPC, moreover, many clients need the FPC assembly, that is most of the SMT factory not familiar with. Fortunately this is our advantage, 80% of our FPC clients chose us to finish the FPC assembly, because we take care of every single detail about the processes of FPCBA.

Single layer FPC is most using in the lighting industry and display industry as a light provider device’s part. We take very care about the feature of these industries, the stableness, long life span, proper conductivity are the main features of the FPC used in lighting and display.

FPC prototyping means fast producing, quick test and immediately delivery.

With our professional equipment, we can efficiently do the drilling, PTH, lines, etching, etc. And applied the flying probe machine, fast test is available. FPC prototype in 3 days is abusolutely ok for us, and this service helped our client faster their product exploring.

And self-owned lines of surface treatment helps us to control the quality of OSP, ENIG on the surface of Flexible Circuit Board.

If need FPC prototype including Single layer FPC, Double sided FPC or Multilayer FPC, pls contac us immediatly! Also FPC assembly is available. Know more about the FPC assembly pls view this post: The differences need to know between the FPC assembly and Rigid PCB assembly

What is Flexible Printed Circuit (FPC)-Materials

The Materials of Flexible Printed Circuit (FPC)

Mainly consisted with 4 parts: Copper Film, Cover Film, PI Striffener Film, Adhesive Sheet

Specific materials involved are as below:

Copper: can be ED-Electro Deposit or RA-Rolled Annealed (which is usually used for the FPC for mobile). Usually 1oz or 1/2 oz thickness (copper thickness: 1/2oz =0.7 mil=0.018mm)
Base Film: normal material is PI (polyimide). Usually 1mil or 1/2 mil thickness.
Adhesive: thickness is up to customers’ request. usually epoxy resin thermosetting adhesive
Cover Film: Used for surface insulation. Normal material is PI (polyimide). usually 1mil or 1/2 mil thickness.
PI Stiffener Film: Enhance the mechanical strength of FPC. Usually 5mil or 9mil thickness.
Release Paper: To avoid the adhesive stained
Stiffener Material: Usually use PI, FR-4 and steel sheets
Adhesive sheet between layers: 1mil epoxy resin thermosetting adhesive

Note: 1mil =1/1000in=0.025mm. 1mim=40mil

So, for each single layer Flexible Printed Circuit (FPC), the thickness is about: 0.5mil cover film + 0.5mil adhesive + 1/2oz copper +
0.5mil adhesive + 0.5 base film = 2.7mil=0.0675mm
