Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 - 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board.

Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on.

    What is the PCB thick copper plate?The thick copper plate is displayed in the waiting process, with certain technical threshold and operation difficulty, and the cost is also relatively expensive. A layer of copper foil is bonded in the outer layer of FR-4. When the copper thickness is 2oz is completed, it is defined as the thick copper PCB plate.PCB thick copper plate has a very good extension performance, not limited by the processing temperature, high baking point can be used when oxygen blowing, low temperature unchanged brittle and other hot baking welding methods, and also fire prevention, spread in non-combustible materials, thick copper PCB its thickness is different, the specific application occasions are also very different.
  • The four layer of 2 OZ heavy copper PCB comes from the best technology in China The four layer of 2 OZ heavy copper PCB comes from the best technology in China
    In PCB proofing, a layer of copper is bonded on the fr-4 surface. When copper thickness ≥ 2OZ is carried out, it is defined as thick copper plate. Its thickness is different, the actual usable place is also very different.
  • The 14-layer of 5OZ heavy copper PCB comes from the best technology in China The 14-layer of 5OZ heavy copper PCB comes from the best technology in China
    Ultra-thick copper technology can be seamlessly connected to ordinary circuits.After designers and manufacturers negotiate manufacturing tolerances and capabilities, ultra-thick copper and ordinary circuit boards can be wired together with the minimum limit that can be achieved.
  • Six layers of 2OZ thick copper plate is from the best technology in China Six layers of 2OZ thick copper plate is from the best technology in China
    In PCB proofing, a layer of copper is bonded on the fr-4 surface. When copper thickness ≥ 2OZ is carried out, it is defined as thick copper plate.
