Heavy Copper PCBs feature two or more conductive copper layers, significantly thicker than those found in standard PCBs. These robust boards are designed to handle higher electrical currents and manage greater thermal loads efficiently.
Heavy Copper PCBs are constructed with multiple conductive copper layers. The conductive foil used in these PCBs is notably thicker than in standard variants.
During manufacturing, the inner layers are processed in pairs on a core, and then bonded together using prepreg, which serves as the insulating layer.
This multi-layer setup allows for components to be mounted on both sides of the PCB, with additional tracking and electrical connections inside the board. Vias are employed to create electrical connections between the various layers, ensuring seamless functionality across the board.
