High Thermal Conductivity Of Copper Substrates

Shenzhen Inno Circuit Co.,Ltd | Updated: Sep 20, 2017



Copper substrate is the most expensive metal substrate, the cooling effect than aluminum substrates and iron-based plate are many times better, applicable to special products and industries. There are generally submerged Jintongki plate, silver-plated copper substrate, tin-sprayed copper substrate, Base Copper PCB antioxidant copper substrates.

Copper substrate circuit layer requires a large load capacity, which should be used thicker copper foil, the thickness of general 35μm~280μm; Thermal insulating layer is the core technology of copper substrate, Base Copper PCB it is generally composed of special ceramic powder and epoxy resin filled polymer, Small heat resistance (0.175), good viscoelastic properties, heat aging ability, Base Copper PCB can withstand mechanical and thermal stress.

The quality reliability of copper substrate is the most expensive one of the metal substrates, with the Jin YU laminated plate as the best copper substrate. The heat dissipation effect is many times better than aluminum substrate and iron-based plate, it is suitable for high frequency circuit and high and low temperature change area and the heat dissipation and building decoration industry of precision communication equipment.

Copper substrate metal base plate is the support component of copper substrate, requires high thermal conductivity, generally is copper, also can use copper (in which copper can provide better thermal conductivity), suitable for drilling, Base Copper PCB punching and cutting and other conventional machining.
