Heavy copper PCBs — boards with copper weights of 3 oz/ft² and above, reaching up to 20 oz/ft² in extreme applications — are the backbone of modern power electronics: EV battery management systems, industrial motor drives, high-current power supplies, solar inverters, and aerospace power distribution units. They are engineered to carry currents that would vaporize a standard 1 oz board's traces. But that capability comes with a fundamental engineering challenge: heat. Every a

Launching a hardware product is one of the most capital-intensive challenges a startup can face. Unlike software, you can't push a patch overnight. Every design revision means new boards, new components, new testing — and in traditional electronics manufacturing, that means large minimum order quantities, long lead times, and costly tooling fees that can cripple a pre-revenue company. Small batch SMT (Surface Mount Technology) assembly changes that equation entirely. By allow

Custom heavy-copper PCBs (typically 3oz to 20 oz+ copper thickness) are essential for high-current, high-power, and thermal-management applications. They are also good at power electronics, electric vehicles (EV), solar inverters, automotive systems, welding equipment, and industrial power supplies, where even the standard FR-4 boards are not able to support the current load or heat dissipation. It is common to encounter problems with sourcing custom heavy copper PCBs using g
