Product Specifications
Product Description
Copper base plate is one of the most expensive in the substrate metal, cooling effect is better than aluminum base plate and the iron base board are a lot of times, is applicable to special product and industry.
Usually have a heavy gold copper substrate, silver plated copper substrate, tin copper substrate, copper oxide substrate resistance, etc.
Copper base board circuit layer with a lot of current-carrying capacity, thus should use thicker copper foil and the thickness of the general 35 microns to 280 microns; Thermal insulation layer is copper substrate core technology, it usually is made up of special ceramic powder and epoxy resin filled polymer composition, thermal resistance is small (0.175), viscoelastic can good, has the ability of thermal aging, able to withstand mechanical and thermal stress.
Copper substrate metal base is copper substrate support components, requires high heat conductivity, usually copper, also can use copper (copper plate can provide better thermal conductivity), suitable for drilling, punching and shearing and cutting and other conventional mechanical processing.
