1. Something About Flexible PCB Knowledge
What is a Flexible Printed Circuit?
Flexible Printed Circuit short for FPC.Also known as flexible circuit boards, flexible printed
circuit boards, flexible circuit boards, referred to as soft board or FPC. With high density wiring,
light weight, thin features. Mainly used in mobile phones, laptops, PDA, digital camera, LCM,
and many other products. FPC flexible printed circuit is made of polyimide or polyester film as a
substrate made of a highly reliable, excellent flexible printed circuit. The combination in
accordance with the substrate and the copper foil by mode, the flexible circuit board may be
divided into two categories: a flexible plastic sheet and non-adhesive flexible board. Where no
glue than the price of a flexible sheet of plastic flexible plate is much higher, but its flexibility, the
copper foil and the substrate binding, pad flatness and other parameters are also better than a
plastic flexible board. Therefore, it is generally used only for those demanding applications, such
as: COF (CHIP ON FLEX, flexible panel mount bare chip, pad flatness demanding) and so on.
Because its price is too high, the current application on the market most flexible board still has a
flexible plastic sheet. Flexible plate with adhesive. Since the flexible board is mainly used for
bending the occasion requires, if the design or process is unreasonable, prone to micro-cracks,
open welding defects. Here is the structure of the flexible circuit board on its design, process the
special requirements.
FPC Product Features:
1. Freely bending, folding, winding, can freely move in three-dimensional space and stretching.
2. Thermal properties, and can be used to reduce the size F-PC.
3. To reduce the weight, small size, thin, so as to achieve the integration element device and a
wire connection
FPC capability:
The capability of Wonderful PCB is from 1layer to 6layers and we can make all kinds of surface
finish, such as lead free HASL, Immersion gold, immersion TIN, immersion silver. Besides, we
can make flex-rigid PCB from 1layer to 6layer.
