October 15, 2025 - San Mateo, California - San Francisco Circuits announces its
Heavy Copper PCB Manufacturing & Assembly Capabilities,
and why it matters. As electronic systems
demand higher power and improved thermal performance, heavy copper PCBs have become
essential for high-current, high-reliability applications across industries. San
Francisco Circuits latest capabilities page on heavy copper outlines how increased
copper thickness enhances current capacity, thermal conductivity, and mechanical
strength in demanding environments.
Why Heavy Copper Matters
By utilizing copper weights from 4 oz. to 10 oz. per square foot, heavy
copper PCBs support higher current flow, improved heat dissipation, and greater
structural durability compared to standard designs.
Key Advantages:
- Current Carrying Capacity - Supports high current with minimal voltage drop.
- Thermal Management - Reduces heat buildup for better reliability.
- Mechanical Strength - Resists warping and cracking under stress.
- Design Efficiency - Enables smaller, more efficient layouts.
Advanced Heavy Copper Production Capabilities
San Francisco Circuits offers fast-turn fabrication and assembly for complex
heavy copper builds, including:
- Copper plating up to 10 oz/ft²
- Integrated thermal vias and heat sinks
- Sequential lamination for multilayer designs
- Lead times as quick as 72 hours for bare boards
From defense and aerospace to industrial power and automotive systems, heavy
copper PCBs deliver the performance needed for today’s high-power electronics.
