2-layer aluminum PCB is a kind of high performance circuit board. It uses aluminum base material as the substrate, has excellent heat dissipation performance and mechanical strength, widely used in LED lighting, power supply, automotive electronics, communication equipment and other fields.
1. Manufacturing process
The manufacturing process of 2-layer aluminum PCB is different from that of ordinary FR4 PCB, mainly including the following steps:
1. Substrate preparation: aluminum base material is processed by cutting, polishing, cleaning and other processes to make the substrate meet the requirements.
2. Printed circuit pattern: the circuit pattern is transferred to the aluminum substrate through lithography technology to form a conductive pattern.
3. Chemical etching: etching away the aluminum material that does not cover the circuit pattern to form a conductive path.
4. Gold plating layer: a layer of metal is plated on the conductive pattern to improve electrical conductivity and corrosion resistance.
5. Welding components: The electronic components are fixed on the aluminum substrate through welding technology.
6. Testing and packaging: Electrical performance testing and appearance inspection of aluminum PCB are carried out before packaging.
