12OZ Heavy copper PCB
12OZ Heavy copper PCB is a layer of copper foil bonded on the glass epoxy substrate of printed circuit board. When the copper thickness is ≥ 2oz, it is defined as Heavy copper PCB. Performance of Heavy copper PCB: 12OZ Heavy copper PCB has the best elongation performance, which is not limited by processing temperature. Oxygen blowing can be used at high melting point, and brittle at low temperature. It is also fireproof and belongs to non combustible material. Even in highly corrosive atmospheric environment, copper board will form a strong, non-toxic passivation protection layer.

Heavy copper PCB
Printed circuit boards are usually bonded with a layer of copper foil on glass epoxy substrate. The thickness of copper foil is usually 18 μ m, 35 μ m, 55 μ m and 70 μ M. The most commonly used copper foil thickness is 35 μ M. When the weight of copper is more than 70UM, it is called heavy copper PCB
