What Are The Common Types Of PCBA Substrate?

1. FR-4 board is an epoxy board with high mechanical and dielectric properties, good heat resistance and moisture resistance, and good mechanical processing.


2. The aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided panel is composed of a three-layer structure, which is a circuit layer (copper foil), an insulation layer, and a metal base layer. Aluminum substrates are often used in LED lighting products. There are positive and negative sides, the white side is the welding of the LED pin, the other side of the aluminum color, generally coated with conductive paste after contact with the thermal part.


3, FPC board is made of polyimide or polyester film as a substrate with a highly reliable, excellent flexible printed circuit board. With high wiring density, light weight, thin thickness, good bending characteristics. For mobile phones, hard drives and other high-end products.


According to different product uses, the PCBA substrate selection will be different. Generally, the higher the end product, the higher the PCBA substrate used and the more expensive.
