Aluminum PCB Capabilities

1. Heat dissipation

At present, many double-sided and multi-layer boards have high density and high power, and it is difficult to dissipate heat. Conventional printed board substrates such as FR4 and CEM3 are poor conductors of heat, and the layers are insulated, so the heat cannot be dissipated. Local heating of electronic equipment cannot be ruled out, resulting in high temperature failure of electronic components, and aluminum substrates can solve this heat dissipation problem.

2. Thermal expansion

Thermal expansion and contraction are the common nature of substances, and the thermal expansion coefficients of different substances are different. The aluminum-based printed board can effectively solve the problem of heat dissipation, so as to alleviate the problem of thermal expansion and contraction of different components on the printed board, and improve the durability and reliability of the whole machine and electronic equipment. In particular, it solves the problem of thermal expansion and contraction of SMT (Surface Mount Technology).

3. Dimensional stability

Aluminum-based printed boards are obviously much more stable in size than printed boards with insulating materials. Aluminum-based printed boards and aluminum sandwich panels are heated from 30 °C to 140~150 °C, and the size change is 2.5~3.0%.

Aluminum PCB is a metal circuit board material, composed of copper foil, Dielectric Layer and Baise Layer, As shown below:

Circuit Copper Layer: Printed circuit foil with a thickness of 1 oz to 10 oz.

Dielectric Layer: The dielectric layer is a layer of thermally conductive insulating material with low thermal resistance. Thickness: 0.003" to 0.006" inch

Aluminum Layer: The base layer is usually aluminum or can also be copper. The most commonly used thickness is 0.040" (1.0 mm), although many thicknesses are available for selection.
