Metal core PCBs use a base metal such as aluminum, copper or a special alloy to dissipate heat away from sensitive components and other critical parts of the design. This allows heat transfer that is 8 or 9 times faster than in traditional FR4 boards. Metal core PCBs are ideal for applications such as LED lighting, power converters and motor control. We can provide aluminum or heavy copper core PCBs for prototypes or production quantities.

HDI PCB technology is one of the fastest growing areas of the PCB market. HDI circuits provide much higher wiring densities than standard PCBs, and incorporate features such as blind/buried vias, vias-in-pad and micrometre-level circuit geometries. HDI technology can reduce the size and weight of your boards while enhancing signal transmission and reducing signal loss. We can provide a variety of board construction methods and materials, including flexible HDI PCBs.
