Aluminum substrate PCB’s characteristics

Aluminum substrates PCB are widely used in the electronics and lighting industries, so why are aluminum substrates widely used? In fact, the main reason for the widespread use of aluminum substrates PCB is determined by their characteristics and performance. Hitech Circuits Co., Limited. will introduce the performance and characteristics of PCB aluminum substrate.

Performance of PCB aluminum substrate

1. Stability: The stability of aluminum substrates pcb is good, mainly because the size change of aluminum substrates is generally small, which is more stable than printed boards made of all insulation materials on the market.

2. Insulation: The aluminum substrate pcb has excellent insulation performance and high hardness, which can effectively replace fragile ceramic boards, thereby reducing the actual area required for printed boards and eliminating the need for heat sinks. This can improve product heat dissipation, improve product efficiency, and reduce costs.

3. Thermal expansion. The aluminum substrate pcb can improve the heat dissipation function of the product, thus alleviating the thermal expansion of the components on the printed board, while improving the reliability of the product and making the product more durable.

Characteristics of PCB aluminum substrate

1. Aluminum substrate PCB is a low alloy sheet with high plasticity, which has good thermal conductivity, insulation, and process ability. Used in working circuits, it has a good effect on heat dissipation of electrical appliances.

2. When using electrical products, it can effectively reduce the temperature during operation, thereby improving the work efficiency of the appliances and extending the service life of the electrical products to a certain extent.

3. Compared with ceramic substrates, aluminum substrates PCB have higher hardness and are less prone to breakage, making them mechanically durable, with low density and small volume, thus occupying a smaller position in the product.
