Copper Based PCB

We can make Copper Based PCB, Thermoelectric Separation Copper Based PCB.Today i would like to introduce this 2 layer copper core PCB board,in black soldermask and white silkscreen. [email protected] Copper core thickness: 5mm layer Top layer: 3oz copper Prepreg: 0.01-0.03mm thickness, need good quality ok for 1000V Black soldermask White silkscreen Immersion gold all around Generally, there are Immersion gold copper based PCB/Silver plating copper based PCB/Hot air soldering leveling (HASL) copper based PCB/Anti-oxidation copper based PCB.Copper substrates have better thermal conductivity than aluminum substrates and are suitable for heat dissipation in high-frequency circuits and precision communication equipment.The copper substrate circuit layer requires a high current carrying capacity, so thicker copper foil should be used, with a thickness generally ranging from 35 μ m to 280 μ m.The thermal insulation layer is the core technology of copper substrates. The core thermal insulation layer is composed of aluminum oxide and silicon powder, as well as a polymer filled with epoxy resin. It has a low thermal resistance (0.15), excellent viscoelastic properties, and the ability to resist thermal aging, and can withstand mechanical and thermal stress. Advantages of copper based PCB as belows 1.Excellent heat dissipation performance 2. High strength and rigidity 3. Good processing performance APPLICATIONS as belows Lighting Automotive Communication equipment Audio Power supply Medical tools If you are interested, please contact me and will send you quotation for reference,thank you so much
