Key Product Highlights

Uniform 6 oz copper thickness on all 4 layers delivers exceptional current-carrying capacity and minimal resistive loss,ideal for power distribution,motor drives,and high-current circuits.

Robust 3.2mm board thickness provides outstanding mechanical strength and heat dissipation for demanding environments.

Optimized Thermal Performance

Heavy 6 oz copper planes act as integrated heat spreaders,effectively dissipating heat from high-power components and reducing hot spots.

FR4 TG130 material offers reliable performance for standard high-power applications,with good thermal and mechanical stability.

Durable Construction&Enhanced Reliability

Wide trace/space design(0.508mm minimum) ensures high manufacturing yield,reduced risk of trace damage,and reliable operation under thermal cycling.

Immersion Gold(ENIG)with 2µ″Au provides excellent solderability,oxidation resistance,and a flat surface for consistent component placement.

Simplified Power Routing&Layout

Heavy copper layers allow for compact power routing,reducing the need for multiple parallel traces or external bus bars.

4-layer design with symmetrical stack-up maintains balance, preventing warpage and ensuring reliable assembly.

Why Choose This Heavy Copper PCB?

Ideal for applications requiring high current(50A+per layer)and superior thermal management.

Eliminates the need for external heat sinks or complex cooling solutions in many designs.

Provides long-term reliability in high-vibration,high-temperature,or high-power cycling conditions.
