Why Choose Aluminium Sheet for PCB
Aluminum sheet for PCB is of cheap price and good heat dissiation. The alu sheet for pcb is an idela choice for lighting products, audio equipment, power equipment,etc. Learn more.
Ceramic PCB is relatively stable, and it is not easy to deform under high temperature and humidity environment, but the price is relatively expensive and fragile, which is often used in high-end products. But for the common goods such as LED light panels, is there a PCB substrate with cheap material and good heat dissipation?
The answer is aluminum sheet for PCB. As we all know, aluminum is a kind of metal and has conductivity. How can it be used as a PCB material? This is because the aluminum substrate consists of a three-layer structure: copper foil, insulating layer and metal aluminum. 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, the thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface condition and cost of the metal substrate must also be considered. Considering the cost and technical performance, aluminum drilling entry sheet is an ideal choice. Available aluminum plates are 6061, 5052, 1060, etc.
The aluminium drilling entry sheet is commmonly used in LED lighting products. It has two sides: the white side is soldered with LED pins, and the other side is in the natural color of aluminum that is coated with the thermal conductive paste.
Its other main applications includes:
Lighting products: High-power LED lighting products.
Audio equipment: Preamplifier, power amplifier, etc.
Power equipment: DC/AC converter,solid state relay,etc.
Communication products: High-frequency amplifiers, filter appliances, and transmission circuits.
