ABSTRACT:
Spacing elements are integrally formed on the constituent surfaces of conductive interfaces of electronic circuit device components for providing uniform thickness solder or other bonding film between the surfaces. The interfaces may be electrically conductive interfaces such as those defined between leads and substrate contact pads as well as thermally conductive interfaces such as those defined between heat sinks and substrates. Any suitable spacers which maintain the constitutent surfaces a selected distance apart when the components are pressed together may be employed such as edge and corner flanges, convex dimples, annular protrusions, tangs, among others. A tool is disclosed for forming the annular protrusions that is advantageously employed with comparatively thick electronic circuit device components and with laminated electronic circuit device components having a comparatively hard layer.
