Aluminum PCBs are printed
Circuit Boards which contain a thin layer of conductive dielectric material.
They are also known as Aluminum Clad, Aluminum base, MCPCB (Metal Clad Printed
Circuit Board), IMS (Insulated Metal Substrate), Thermally Conductive PCBs etc.
Aluminum PCBs were developed in the 1970s, soon after which they’re
applications increased dramatically. The first application was their use in Amplification
Hybrid Integrated Circuits. Now they are being used at a large scale due to
which it is necessary for us to have an idea of Aluminum PCBs and their
importance.Structure of Aluminum PCBs: Aluminum PCBs are aluminum
based CCLs (CCL is a type of base material of PCBs). AluminumPCBs are actually
quite similar to FR4 PCBs. The basic structure of Aluminum PCBs is four
layered. It consists of a layer of copper foil, a dielectric layer, an aluminum
base layer and aluminum base membrane.· Copper Foil Layer: the copper layer used is
relatively thicker than normal CCLs ...
