What are the commonly used types of PCBA board?

1, FR – 4 sheet is a kind of epoxy plate, has high mechanical properties and dielectric properties, good heat resistance and wave resistance, and good machinability.

2, aluminum plate with good heat dissipation function is a kind of metal base copper-clad r.p. panel and general single panel composed of three layers structure, respectively is the circuit layer (copper foil), insulation and metal base. Aluminum substrate is often used in LED lighting products. Has two sides, the welding of the LED pin on one side of the white, the other side aluminum instinctive quality, usually apply thermal coagulation pulp after contact with parts of thermal conductivity.

3, FPC board based on polyimide or polyester film base material made of a kind of high reliability, excellent flexible printed circuit board. With the high density of wiring, light weight, thin thickness, good bending sexual characteristics. Used in the high-end products such as mobile phones, hard disk drives.

According to the different product use, the choice of the PCBA is different, usually, the more high-end products, PCBA substrates used by the more advanced, the price is more expensive.
