Aluminum substrate PCB’s Performance and 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.
An aluminum PCB significantly improves a product’s heat dissipation. This helps to control the thermal expansion of components on the printed board, enhancing product reliability and extending its lifespan.
By minimizing the risks associated with overheating, aluminum PCBs contribute to better long-term performance, especially in high-power LED lighting and power electronics.
Characteristics of PCB aluminum substrate
1. High Plasticity and Processability
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. Temperature Control for Better Efficiency
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.
Mechanical Durability and Compact Size
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.
