Lightweight Aluminum PCB For Automotive Electronics Custom PCB Board

♦ What is Aluminum PCB?

Aluminum substrate is a functional circuit board with aluminum (or aluminum alloy) as the base material. It is mainly composed of circuit layer (copper foil), insulation layer and metal base layer. Its core value lies in efficient heat dissipation and high power carrying capacity. It is widely used in electronic devices that are sensitive to heat or require high current drive.

♦ Features of Aluminum PCB

• • ​​High mechanical strength​​: It has good mechanical properties, can withstand certain impacts and pressures, and is not easily damaged during manufacturing, transportation and use.
  • ​​Strong corrosion resistance​​: The surface is oxidized to form a dense oxide film, or a special coating is used to make it stable in a humid and chemically corrosive environment.
  • ​​Good electrical insulation​​: The insulation layer uses high-performance insulating materials, which can effectively isolate the current, prevent short circuits and leakage, and ensure the safety and stability of electronic products.
  • ​​Light weight​​: Compared with some metal substrates, aluminum has a lower density, which reduces the weight of the equipment while ensuring performance.

♦ Applications of Aluminum PCB

• • ​​LED lighting​​: High-power LED lamp beads (such as street lights, stage lights, and car headlights) need to dissipate heat quickly to improve light efficiency and life.
  • ​​Power module​​: High-power density circuits such as switching power supplies and inverters rely on aluminum substrates to reduce temperature rise.
  • ​​Automotive electronics​​: Stable operation in high-temperature environments such as engine control units, car light drivers, and charging piles.
  • ​​Audio equipment​​: Amplifier circuits use aluminum substrates to reduce the impact of heat on sound quality.
    ​​Industrial control​​: High-power consumption equipment such as motor drives and power converters.
