Heavy Copper PCBs Fabrication_X-Parts

Heavy Copper PCBs

IPC association doesn’t have a set definition on Heavy Copper PCBs. Copper foil thickness for conventional PCBs is usually 0.5-2 OZ, so we can call PCBs which use 3 OZ copper or higher in their inner and / or outer layers as Heavy Copper PCBs.

Heavy Copper PCBs are designed and manufactured in thicker copper thickness and wider traces which enables higher current-carrying capacity for applications working under high current or high voltage conditions.

Applications of Heavy Copper PCBs

With the greater performance on thermal conductivity, current-carrying capacity, mechanical strength and dissipation capability, we see the utilization of Heavy Copper PCBs growing rapidly in recent years, it has been a very important segment of our manufacturing service. They are widely applied to various fields including but not limited to:

Power Supplies
Power ConvertersThicker Copper PCBs
High Output Inverter
High Power Motor Driver
Battery Management System (BMS)
Automotive (EV, HEV etc.)
Industrial Control System
Industrial Robots
New Energy
