Metal PCB Fabrication
Metal PCB Fabrication.We offer Metal PCB thickness from 0.1mm to 7.0mm. Metal materials include Copper core and Aluminium base. The cooling effect is very good.
Metal Core PCB includes the design and production of printed circuit boards (PCB’s) with a metal core, intended for use with LED-based Solid State Lighting and other applications where heat dissipation is required.
Copper core pcb is the most expensive one of the metal substrates, and its heat conduction effect is many times better than that of the aluminum substrate and the iron substrate. It is suitable for high-frequency circuits and regions with high and low temperature variations and the heat dissipation and architectural decoration industries of precision communication equipment. Generally, there are a gold-plated copper substrate, a silver-plated copper substrate, a tin-plated copper substrate, an anti-oxidation copper substrate, and the like. The copper substrate circuit layer is required to have a large current carrying capacity, so thick copper foil should be used, and the thickness is generally 35μm~2000μm; the thermal conductive insulating layer is the core technology of the copper substrate, and the core thermal conductive component is aluminum oxide and silicon powder. It consists of a polymer filled with epoxy resin, low thermal resistance (0.15), excellent viscoelasticity, resistance to heat aging, and ability to withstand mechanical and thermal stresses. The copper substrate metal base layer is a supporting member of the copper substrate, and is required to have high thermal conductivity, generally a copper plate, or a copper plate (in which the copper plate can provide better thermal conductivity), which is suitable for conventional machining such as drilling, punching and cutting.
With the rapid development of the world’s electronics industry, the power density of electronic, LED, smart devices, medical equipment, new energy equipment and other products has increased. How to find a way to heat dissipation and structural design has become a huge design in today’s electronics industry. Demand, and the thermal conductivity, electrical insulation performance and mechanical processing performance of the thermoelectric separation copper substrate are undoubtedly one of the effective means to solve the high heat dissipation problem.
