Aluminum PCB and FR4 PCB
aluminum substrate (metal substrate radiator [including aluminum-based board, copper-based plate, iron-based plate]) is a low-alloy Al-Mg-SI system high-plastIC alloy plate. This has good thermal conductivity and electrical insulation performance and mechanical processing performance.
Compared with the traditional FR-4, the aluminum substrate adopts the same thickness and the same line width, which can carry higher current, which can resist 4500V and the heating coefficient is greater than 2.0. The industry is mainly aluminum substrate.
