What is copper prototype board used for?

Copper prototype board quality reliability to kingboard laminate for good, Copper prototype board is one of the most expensive metal substrates, heat dissipation effect than aluminum substrates and iron substrates are many times better, suitable for high frequency circuits and high and low temperature change of large areas and precision communication equipment heat dissipation and building decoration industry.

Generally, there are gold plated copper substrates, silver plated copper substrates, tin prayed copper substrates, antioxidant copper substrates. Copper printed circuit board circuit layer requires a large current-carrying capacity, so should use thick copper foil, the thickness of the general 35 m~280 m; Thermal insulation layer is the core technology of copper substrate. The core thermal conductivity component is composed of aluminum oxide and silicon powder and epoxy resin filled polymer, with small thermal resistance (0.15), excellent viscoelastic properties, thermal aging resistance and mechanical and thermal stress tolerance. The metal base of copper substrate is the supporting member of copper substrate, which requires high thermal conductivity, generally copper plate, copper plate can also be used (copper plate can provide better thermal conductivity), suitable for drilling, punching, cutting and other conventional mechanical processing.
