Elpor steel metal core printed circuit boards (MCPCBs) from Heatron are said to offer the unique advantage of a porcelain ceramic coating. The coating provides the primary electrical insulation between the printed circuit and the steel core. It is applied in a proprietary dip process that allows coating of both sides, edges and holes. The high temperature glass-like coating also helps the circuit board resist moisture and corrosion. Elpor steel can be fabricated to accommodate custom board designs with what is said to be far greater resistance to mechanical shock than standard PCBs.
