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.

Clarifications of FPC
According to the combination of base material and copper foil, flexible circuit board can be divided into two types: flexible board with adhesive and flexible board without adhesive. The price of non-adhesive flexible PCB is much higher than that of adhesive flexible PCB, but its flexibility, bonding force between copper foil and substrate and flatness of solder are also better than that of adhesive flexible PCB. So it is only used in the high demand situations, such as the: COF (CHIP ON FLEX, flexible board with bare chip, the high flatness of the pad) and so on. Because its price is high, most of the flexible PCBs used in the market are still adhesive flexible circuit board. Because the flexible circuit board is mainly used in the situation where bending is required, if the design or process is not reasonable, it is easy to produce micro-cracks, welding and other defects.
Economy of Using FPC
If the circuit design is relatively simple, the total volume is small, and the space is suitable, the traditional internal connection is much cheaper. Flexible circuits are a good design option if the circuit is complex, processes many signals or has special electrical or mechanical requirements. When the size and performance of applications exceed the capacity of rigid circuits, flexible assembly is the most economical. A 12mil pad with a 5mil through hole and a flexible circuit with 3mil lines and spacing can be fabricated on a thin film. Therefore, it is more reliable to mount the chip directly on the film. There is no flame retardant that could be an ion source. These films may be protective and solidified at higher temperatures to obtain higher glass transition temperatures. Flexible materials are less costly than rigid materials because they are free of connectors.
