What are Aluminum PCBs?
Aluminum printed circuit boards have the ability to dissipate heat for electronic products. An aluminum PCB is one of the most commonly used types. It features standard FR4 laminate and an aluminum core. The circuit board helps in heat dissipation effectively with the help of a thermal clad layer that it features. These printed circuit boards are most widely used in applications involving tight tolerances and high power.
The Three Layers in an Aluminum PCB
Aluminum PCBs are designed and manufactured differently as compared to the other types of PCBs. This printed circuit board is made up of three main layers.
The circuit layer of the aluminum circuit board consists of a copper foil. These copper foils can be used in varying weights from 1 to 10 ounces.
Thermal Insulation Layer
The thermal insulation layer of the circuit board is made up of the ceramic polymer. This polymer has a good thermal resistance and viscoelastic properties. It is the most important layer and helps protect the circuit board from potential mechanical and thermal stresses.
The base layer is made up of aluminum alloy substrate. These types of PCBs are an ideal match for through-hole technology. Thanks to the presence of aluminum in them.
How is an Aluminum PCB Manufactured?
In the process of manufacturing an aluminum PCB, a thin layer of dielectric is added between the circuit layer and the base layer. This layer of dielectric is both electrically insulating, as well as thermally conductive. After adding the dielectric layer, the circuit layer or the copper foil is etched. This allows you to get the required pattern. The metal base layer of the circuit board, with the help of a thin dielectric, helps remove all the heat from the circuit.
What are The Application Areas of Aluminum PCBs?
Aluminum printed circuit boards are among the most widely and commonly used circuit boards? They find their use in a vast variety of applications like these:
Surgical Lighting Tools
Power Transmission Systems
Medical Operating Theatre Lighting
Tail Light Assemblies
