Thick 3.2mm Aluminum Printed Circuit Board For LED PCB Fabrication

Aluminum PCB Printed Circuit Board for LED pcb fabrication

The performance of Aluminum PCB: 

1. Thermal Dissipation

At present, a lot of double side Aluminum PCB, multilayer Aluminum PCB with high density, large power and difficulty in heat dissipation. Conventional FR4 and CEM3 PCB are poor conductors of heat, which are insulated between layers and cannot heat dissipation, leading to high temperature failure of electronic components, and aluminum PCB can solve the problem of heat dissipation.

2. Thermal Expansion

Thermal expansion and cold contraction are the common nature of substances, and the coefficient of thermal expansion of different substances is different. Aluminum based printed board can effectively solve the problem of heat dissipation, thus alleviating the problem of heat expansion and cold contraction of the components on the printed circuit board, and improving the durability and reliability of the whole machine and electronic equipment, especially to solve SMT (surface mount technology) thermal expansion and cold contraction problem.

3. Dimensional Stability

The size of aluminum base PCB is obviously much more stable than that of insulated printed boards. Aluminum based printed circuit boards are heated from 30℃ to 140~150℃ with size variation of 2.5~3.0%.

4. Other Performance

Aluminum PCB has other good performances, such as have shielding effect; Replace the ceramic substrate and component of radiator; improve product heat resistance and physical properties; Reduce production costs and labor.
