Abstract
A power resistor assembly includes an anodizable metal substrate, preferably an aluminum alloy, having an insulating anodized coating on at least one flat side. A resistive or partially conductive ink is screen printed on the anodized coating in a pattern to provide one or more resistors. The ink has a curing temperature below 660.degree. C. which is below the melting point of aluminum. The resistor assembly is a vehicular fan motor controller or an interior dimmer switch. The fan motor controller has resistor ends which are soldered with tin-lead solder.
