An aluminum PCB is a printed circuit board that contains a thin layer of conductive dielectric material. They are also called aluminum cladding, aluminum base, MCPCB (metal clad printed circuit board), IMS (insulated metal substrate), thermal conductive PCB, etc. Aluminum PCBs were developed in the 1970s, and soon their applications increased sharply. The first application is their use in amplifying hybrid integrated circuits. They are being used on a large scale, so we must understand aluminum PCB and its importance.
The aluminum PCB manufacturing process
The manufacturing process of aluminum PCB with OSP surface finish: Cutting→Drilling→Circuit→Acid/alkaline etching→Solder Mask→Silkscreen→V-cut→PCB Test→OSP→FQC→FQA→Packing→Delivery.
The manufacturing process of aluminum PCB with HASL surface finish: Cutting→Drilling→Circuit→Acid/alkaline etching→Solder Mask→Silkscreen→HASL→V-cut→PCB Test→FQC→FQA→Packing→Delivery.
PCBHERO can provide the aluminum core PCB with the same surface finish process as FR-4 PCB: Immersion Gold / thin / silver, OSP, etc.
