What are the characteristics of flexible circuit boards and rigid circuit boards?
Rigid circuit boards include phenolic paper laminates, epoxy paper laminates, polyester glass mat laminates and epoxy glass cloth laminates. The flexible printed circuit board is also called a flexible printed circuit board or FPCB.
Flexible circuit board, also called FPC, soft board, is a kind of printed circuit board with polyimide or polyester film as the base material, high reliability and high flexibility.
So, what are the characteristics of flexible circuit boards and rigid circuit boards?
1. The characteristics of rigid circuit boards
1. High density. With the improvement of circuit integration and the advancement of placement technology, high-density printed circuit board technology has become very mature.
2. High reliability. Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time.
3. Designability. For various performance requirements of PCB (electrical, physical, chemical, mechanical, etc.), circuit board design can be realized through design standardization.
4. Productivity. Through modern management, standardization, scale (quantity), and automated production can be carried out, and consistent product quality can be ensured.
5. Testability. Through relatively complete test methods, test standards, various test equipment and instruments, etc., detect and identify the service life of PCB products.
2. Features of flexible circuit board products:
1. Small size and light weight, suitable for the development of high density, miniaturization, light weight, thinness and high reliability electronic products.
2. High flexibility, free to bend, roll up, twist, fold and 3D wiring to realize the integration of assembly and wire connection.
3. It has excellent electrical properties, high temperature resistance and flame retardancy.
4. It has high assembly reliability, which provides convenience for circuit design, reduces assembly workload and ensures circuit performance.
Comparing the characteristics of the two, PCB china we can easily find the difference between the two.
