The biggest difference between a FPCB and a conventional hard circuit board is that the FPCB can be bent, folded or repeatedly moved in many ways. In order to realize all the possibilities of the FPCB, designers mostly use a variety of structures to meet the various needs of different products, such as single-layer board, double-layer board, multi-layer board and rigid- flexible board.
There are two types of FPCB currently on the market: printed (etched) board and silk screened board. The silk-screened FPCB is also called polymer thick film FPCB, which is different from the common printing etching technology. The FPCB technology uses other processes to directly use silk screen conductive ink as a conductor on the dielectric film to form the circuit we need. Although the application of FPCB is expanding, the printed FPCB is still the most widely used of the two.
Flex to install is the most common type of rigid flex PCB application. In this circuit application, the board folds only once when the device is assembled or removed. Apart from this, the flex part of the board remains stable throughout use; though some movement may occur in the case of high vibration applications.
By contrast, it is sometimes necessary for a PCB to be able to fold and bend repeatedly during end product use. This type of circuit application is known as dynamic flex. It requires special consideration to ensure the flexible portion of the board can withstand repeated wear. When designed with an appropriate bend radius, these circuit boards can be trusted to last for hundreds of thousands of flex cycles without issue.

Q4. How can we guarantee you receive an good quality product?
For PCB, we will use Flying Probe Test, E-test etc. for it.
For PCBA, we need you to offer us a method or test fixture for the function test.Before that, our inspectors will use microscope and X-ray to check the IC footwelding or bad solder etc.
Q5. How to ship the PCBAs?
For small packages, we will ship the boards to you by DHL,UPS,FEDEX,TNT. Door to door service! For mass production, we could ship by air, by sea.
Q6. What’s the definition of PCB, PWB and FPC and what’s the difference?
PCB is short for Printed Circuit Board;
PWB is short for Printed Wire Board, same meaning as Printed Circuit Board;
FPC is short for Flexible Printed Board.
