What is Aluminum PCB?
Before we look into aluminum PCB, we must have a clear concept of what is PCB?PCB is an acronym of Printed Circuit Board, which uses conductive paths and traces incorporated on a single board that electrically connects different electronic components on the board. Copper is used to provide a conductive path that is laminated on the substrate material.
Aluminum PCB, also referred as metal base PCB, is a type of PCB that consists of copper-clad laminate and a thin dielectric thermally conductive and electrically insulating layer of Aluminium.
The copper foil adopts the desired circuit pattern while the aluminum base allows the heat-dissipating with the help of a dielectric placed between the layers.
Aluminum constructions are mainly divided into three layers
Circuit Layer: It is a copper layer that comes with a thickness of around 1 to 10 oz.
Insulating Layer: A dielectric layer of thermally conductive and electrically insulating material
Base Aluminum Layer: This is mainly composed of copper or aluminum metal substrate. There are multiple thicknesses available, however the most common thickness is 1mm.
