Copper Substrate

Copper substrate is one of the most expensive metal substrates. Its thermal conductivity is many times better than that of aluminum substrate and iron substrate. It is suitable for high-frequency circuits, areas with large changes in high and low temperatures, and in the heat dissipation and building decoration industries of precision communication equipment. Generally, there are immersed gold copper substrates, silver-plated copper substrates, tin-sprayed copper substrates, anti-oxidation copper substrates, etc. The copper substrate has the following advantages: its dielectric constant is stable and the operating temperature is -100°C-+150°C; the peeling strength of the copper substrate is more reliable than the vacuum coating of the ceramic substrate, making circuit processing easier and the production qualification rate higher. Lower manufacturing costs; easy to machine, including drilling, punching, grinding, cutting, etching, etc.
