Heavy copper PCB

Heavy copper PCB support for power, energy and industrial electronics.

MWX PCB helps review copper weight, spacing, heat, plating, etching and delivery risk before heavy copper prototype or low-volume production.

Design screening

Heavy copper boards need DFM before price and lead time are trusted.

Copper Weight

Outer and inner copper thickness must be reviewed with line width, spacing and etching feasibility.

Thermal Load

Power density, copper area and heat paths affect structure, cost and reliability.

Plating & Drilling

Aspect ratio, hole wall copper and finished hole tolerance should be confirmed early.

Lead Time

Heavy copper can extend normal quick-turn lead time and must be quoted case by case.

Applications

Good-fit heavy copper demand.

Power electronics, BMS battery management systems, photovoltaic inverter, transformer, IGBT, charging equipment, power grid monitoring, industrial motor control and energy storage projects.
