PCBCarts aluminium-backed PCBs: heat dissipation and light weight

摘要

Aluminium PCBs contain a dielectric layer between aluminium base and copper foil. The dielectric layer is thermally conductive but electrically insulating, so that it offers better heat dissipation than conventional PCBs. Furthermore, the dielectric layer has such a low thickness that aluminium PCBs are light in weight, compatible with the miniature requirements of modern electronic products.
