Dual Layer Flexible PCB Built on Polyimide With Immersion Gold and PI Stiffener
(FPC’s are custom-made products, the picture and parameters shown are just for reference)
General description
This is a type of flexible printed circuit (FPC) for the application of Wi Fi Antenna. It’s a 2 layer flex board at 0.15mm thick. It contains yellow coverlay (solder mask) and without silkscreen on entire board, and immersion gold is applied on pads. Polyimide as stiffener is applied on the connector part. The base laminate is from Shengyi and they're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 200 pieces are packed for shipment.

Double-Sided Flexible Circuits
As the name suggests, the circuit consists of a thin and flexible base material with copper foil laminated to each side. The outer sides of the finished circuits are frequently provided with coverlays bonded to the outer sides (copper). Plated-through holes in double-sided flexible circuits are usually drilled, instead of punched. Usually the flexible circuits are provided with a coverlays on both sides
Manufacturing Process of Double Sided FPC
Although manufacture of double-sided PTH flexible PCB resembles that of single-sided non-plated-through boards, some of the manufacturing processes are not identical and appear in another sequence. Below it shows the processes of how to manufacture a double sided flexible circuits.
