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.
The application of thick copper plate in PCB proofing is basically ubiquitous. It can be used in a wide range of industries, including a variety of household appliances, new technology products, national defense, diagnosis and treatment and other electronic equipment. Thick copper plate has good widening performance, heat resistance, ultra-low temperature, corrosion resistance, so that electronic equipment goods have a longer life, in addition to the volume of electronic equipment has a very large simplification of assistance. In particular, it is necessary to operate higher voltage and current flow of electronic equipment must be thick copper plate.
