Metal Substrate
A metal substrate is a special type of printed circuit board (PCB) that uses a metal material (such as aluminum or copper) as its core thermally conductive layer. It combines the circuit with the metal substrate through a unique insulating dielectric layer, achieving excellent thermal conductivity and heat dissipation performance. Its core feature is its ability to effectively solve the heat generation problem of electronic equipment during high-power operation. It not only offers a variety of board thickness options ranging from 0.3mm to 6mm, but also supports thick copper designs up to 5oz to carry high currents. With a 10:1 board thickness-to-aperture ratio and line widths and spacings as fine as 3mil, it meets the complex requirements of high-density wiring. With a variety of surface treatment processes, from conventional tin spraying to nickel-plated gold, this type of PCB is particularly suitable for applications with stringent thermal management requirements, such as LED lighting, automotive headlights, power modules, and power converters, ensuring the stability and long life of the equipment during efficient operation.
