Insulated Metal Circuit Boards

Insulated Metal Circuits (IMCs) sometimes called Insulated Metal substrates (IMS) are thermally conductive circuit boards that provide heat sinking and heat spreading ability and therefore allow designers to implement high watt density designs with confidence.

Universal Science works with designers of Electronic equipment to optimize their
Metal Cored Printed Circuit or IMC.

In its unprocessed state, IMC's  consists of a 609mm (24-inch) x (457mm) 18-inch sheet metal base material; the regular or standard is aluminium, but copper is also available. The
thickness of the metal base can be specified between 1mm (0.040") and 6.35mm (0.250").

The base metal is coated with a thin thermally conductive adhesive. This layer provides electrical insulation and also enables a copper circuit layer of between 15 microns (0.5oz) and 0.42 mm (12oz) to be bonded to the assembly. The resultant laminated IMC material can be processed to produce a single layer PCB with built-in thermal management.

It is also possible to produce multi-layer constructions by applying several alternate layers of copper and dielectric to the metal base plate. The use of thru-holes and blind and buried vias creates more complex circuit layouts with greater component densities and therefore flexibility in design.
