Insulated metal substrates have been in use for more than thirty years, but their popularity has increased recently in applications where mechanical strength and rigidity are desired for single-sided boards.

Metal substrates circuitry consists of a metal base plate onto which a copper layer conductor layer is attached with a thermally conductive epoxy dielectric. An aluminum alloy is usually chosen for the base metal for its excellent heat dissipation ability, mechanical integrity, low cost and lightweight construction.
