Aluminum PCB Sheet

Aluminum is a kind of metal with conductivity, how can it be used as PCB entry sheet? The PCB entry sheet is Since there is an insulating layer, can the metal layer be made of other materials besides aluminum? Such as copper plate, stainless steel, iron plate, silicon steel plate, etc.

In addition to the heat dissipation performance of the metal substrate, the thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface condition and cost of the metal substrate must also be considered.

Generally, considering conditions such as cost and technical performance,aluminium PCB sheet is an ideal choice. The available aluminum plates are 6061, 5052, 1060, etc. If there are higher requirements for thermal conductivity, mechanical properties, electrical properties,etc., copper plates, stainless steel plates, iron plates and silicon steel plates can also be used.

The aluminum PCB sheet is commonly used in LED lighting products. There are two sides, the white side is soldered with LED pins, and the other side presents the natural color of aluminum. It is mainly used in LED lamps, audio equipment, power supply equipment, etc. The main advantages of the aluminum sheet for PCB board are fast heat conduction and good heat dissipation performance.

Choosing aluminum substrate is a premise to make economic PCB drilling boards. As a big aluminum sheet supplier, Haomei Aluminum can supply different alloys of aluminum sheets such as 6061, 5052, 1060, 1050,etc. Welcome to leave message below to get the best price.
