FAQs

1. What is a PCB?

A PCB is a printed circuit board, also known as a printed wiring board. It is used in electronics to build electronic devices. A PCB serves two purposes in the construction of an electronic device; it is a place to mount the components and it provides the means of electrical connection between the components.
2. What is a FPC?

A FPC is a flexible printed circuit, and is used as interconnection to transmit signals for electronic products by developing circuits on flexible Copper Clad Laminate through processes of exposure, etching … etc.
3.What types of board can you provide?

We can provide: Single-Sided; Double-Sided; Multi-layer (up to 24 layers); Aluminum base board; Flex and Flex-Rigid board.
4. What is made of a flexible circuit board?

A basic flexible circuit is made of a flexible polymer film laminated to a thin sheet of copper that is etched to produce a circuit pattern. Patterns can be created on both sides of the film. Interconnections are achieved with plated through-holes, yielding an almost unlimited adaptability between various component parts. A polymer overcoat is often added to insulate and environmentally seal the circuit.
5. The benefits of Flexible circuits

Flexible circuits provide many benefits compare rigid PC boards:

1>.A solution to a package problem;
2>. Reduce assembly costs
3>.Replacement for a circuit board and wires;
4>.Reduce weight and space;
5>.Dynamic Flexing;
6>.Thermal management/high temperature applications;
7>.Aesthetics.
6. What information do you need for quick quotations?
