The aluminum boards produced by PCB manufacturers are mostly used for LED lamps. What are the specifications for the production of aluminum base board in the production process? Aluminum boards produced by aluminum board manufacturers are often used in power devices, and the power density is large, so the copper foil is relatively thick. If a 3 oz or more copper foil is used, the etching process of the thick copper foil requires engineering line width compensation, otherwise, the line width after etching will be excessive. The surface of the aluminum boards produced by the aluminum board manufacturer must be protected with a protective [...]
