IRC's Anotherm Technology Provides Superior Thermal Conductivity to Polymer-Based Insulated Metal Substrates

摘要

TT electronics IRC Advanced Film Division has developed a new substrate technology that offers numerous benefits over conventional polymer-based insulated metal substrates (IMS). Designated Anotherm, IRC's new material-consists of a thermally conductive aluminum alloy substrate insulated by a thin, chemically grown, anodized dielectric layer, with solderable screen-printed conductors applied to the anodized layer. Traditional insulated metal substrate technology (IMS) often relies on a polymer or epoxy material that is mechanically applied to a bare aluminum substrate, which requires extensive surface preparation, as well as a minimum thickness of approximately 75 microns. In addition, traditional IMS technology is subject to delamination at high temperatures.
