Why Aluminum PCBs?

Thermal Management

Aluminum conducts heat efficiently, transferring heat away from hot components and preventing damage to sensitive electronics.

Non-Hazardous & Recyclable

RoHS and WEEE compliant, aluminum is non-toxic and fully recyclable without harming soil or water bodies.

Durability

Provides greater strength and resilience compared to fiberglass or ceramic bases, preventing accidental breakages during assembly and use.

Lightweight

Despite being highly durable, aluminum adds minimal extra weight to your product while providing exceptional support.

How We Make Aluminum PCBs

Regular aluminum PCBs usually have three major layers working together to provide optimal performance:

Copper Layer

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.

Insulating Layer

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.

Metal Substrate

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.
