Giant is a well-known PCB Assembly Manufacturer in China with more than 10 years of manufacturing experience. It is also the world's leading PCB Assembly solution provider. So what are the commonly used types of custom PCB Assembly substrates? Now GoodTech will explain it for you.


1. FR-4 board is an epoxy resin board with higher mechanical and dielectric properties, better 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 panel is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. Aluminum substrates are often used in LED lighting products. There are two sides, the white side is aligned with the welding LED, and the other side shows the natural color of aluminum, which will generally be adsorbed to the condensed slurry and contact the activated part.


3. FPC board is made of polyimide substitution or polyester film as the base material, which has high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bendability. Used in high-end products such as mobile phones and hard drives.


According to different product uses, the choice of PCB assembly China substrate will be different. Generally, the more advanced products are used, the higher the PCBA substrate and the more expensive the price.
