Aluminum PCB
Among various types of circuit boards, aluminum substrates are selected from many electronic devices due to their good heat dissipation and mechanical stability. They are ideal for high-power devices and LED applications. Next, let’s take a closer look at aluminum substrates.
What is a Aluminum PCB ? (aluminum pcb board /alu pcb)
Aluminum substrate, also known as metal core substrate or aluminum core substrate, is a circuit board with aluminum as the base material.Unlike traditional circuit boards with FR4 as the base material, aluminum-based materials have good thermal conductivity and can conduct heat away from key components, thereby improving the stability and durability of circuit boards in high-power and high-temperature environments.

advantages of Aluminum PCB
Compared with traditional FR4 PCB, aluminum base PCB has more efficient heat dissipation and better thermal conductivity.
Optimized dielectric layer, advanced aluminum materials, and copper foil layout for maximum thermal conductivity and low thermal resistance.
Rigid pcb construction with an aluminum base layer increases stability, reduces vibration, and protects core pcbs in harsh environments.
Aluminum boards and core technology resist warpage, support high current loads, and offer good thermal insulation for the long term.
As your preferred aluminum PCB manufacturer, each heavy duty aluminum PCB or aluminum PCB prototype reaches global standards (IPC, UL, ISO) to ensure quality.
