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. 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.
