Xekera Systems makes aluminum PCBs, the most popular among metal core boards. Our aluminum substrate PCBs use aluminum core as the base material with standard FR4 over it. The aluminum base acts as a thermal clad layer for dissipating heat efficiently, keeping heat-producing components cool and increasing overall performance.
Aluminum conducts heat efficiently, transferring heat away from hot components and preventing damage to sensitive electronics.
RoHS and WEEE compliant, aluminum is non-toxic and fully recyclable without harming soil or water bodies.
Provides greater strength and resilience compared to fiberglass or ceramic bases, preventing accidental breakages during assembly and use.
Despite being highly durable, aluminum adds minimal extra weight to your product while providing exceptional support.
Regular aluminum PCBs usually have three major layers working together to provide optimal performance:
We use electrolytic copper foil, which we etch to form the printed circuit. This layer holds the SMD components and copper traces form the necessary interconnections. The presence of the aluminum base allows the board to carry more current without heating up compared to traditional FR4 PCBs.
Forming the core of the board, this layer functions as electrical insulator, heat conductor, and bonding material between the copper layer and aluminum substrate. Better thermal conductivity of this layer means better heat management and lower component temperature rise.
We choose aluminum for the substrate based on optimal cost, weight, hardness, strength, thermal coefficient of expansion, and thermal conductivity. Aluminum plates are available as 1000, 1060, 6061 series. For higher thermal conductivity and mechanical properties, we can use stainless steel, copper, iron, or silicon steel.
