Aluminium Based Copper Clad PCBs
This type of PCB is also called aluminum base, aluminium PCBs, aluminum clad or backed, insulated metal substrate (IMS), metal clad (MCPCB), or thermally conductive PCBs.
What are Aluminium based copper clad PCBs?
For a typical metal based single sided PCB, the base laminate is made up of copper foil bonded to a thin, thermally conductive insulating dielectric which is in turn bonded to a thick metal base, usually aluminium. The copper layer is processed in the normal way to create the tracking layer, and the profile is machined to the required shape and size. The aluminium substrate must be protected from the etching chemicals during the manufacturing process. The material is particularly suited for population with surface mounted devices. Though hole components are not appropriate because the metal base material is not an insulator. We offer single sided metal clad PCBs as standard.
