Material Selection – Choosing aluminum substrates (e.g., aluminum base with dielectric layer) for effective heat conduction.
Layer Lamination – Bonding a copper layer to the aluminum base, using a dielectric layer for insulation.
Drilling & Plating – Drilling holes for vias and plating them with copper for electrical connections.
Etching & Imaging – Applying photolithography to create precise circuit patterns on the copper layer, followed by etching.
Surface Treatment – Applying surface finishes such as HASL, ENIG, or OSP for better solderability and corrosion resistance.
Testing & Inspection – Conducting thermal, electrical, and mechanical tests to ensure performance and durability.
Aluminum PCBs feature excellent heat dissipation, durability, and mechanical strength, thanks to their aluminum base. The manufacturing process involves laminating a copper layer onto an aluminum substrate with a dielectric layer for insulation. These PCBs are ideal for high-power applications like LED lighting and automotive electronics, offering enhanced thermal management and reliability in demanding environments.
LED Lighting – Used in high-power LED modules, streetlights, and automotive headlights.
Power Electronics – Ideal for power amplifiers, inverters, and battery chargers.
Automotive Industry – Used in engine control units, electric vehicle power systems, and lighting.
Telecommunications – Supports RF applications, base stations, and high-frequency circuits.
Consumer Electronics – Found in audio amplifiers, computer power supplies, and cooling systems.
