Power Your Designs with Advanced Heavy Copper PCB Solutions
Heavy Copper PCBs are engineered to handle high current loads and extreme thermal conditions, providing superior performance for power electronics, industrial automation, automotive, and renewable energy applications. With copper thickness ranging from 3 oz up to 20 oz per layer, these PCBs ensure low resistance, minimal heat generation, and long-term reliability even under demanding operating conditions.
High Current Capacity
Thick copper layers enable PCBs to carry large currents efficiently, reducing voltage drop and improving energy transmission.
Enhanced Thermal Management
Superior heat dissipation keeps components cooler, extending lifespan and enhancing system stability.
Durable & Reliable
Robust construction withstands harsh industrial environments, including high vibration, temperature cycling, and heavy-duty mechanical stress.
Customizable Design
Supports multilayer, high-power layouts, heavy copper weight, large copper planes, and specialized finishes for specific applications.
Cost-Effective Production
Optimized for low to medium volume, high-precision boards, reducing prototyping and production costs for high-current designs.
