IMPROVING RELIABILITY OF ELECTRONIC HYBRIDS WITH NEW SILICONE MATERIALS
Silicone coating and encapsulating materials are well established products used in environmental protection of car electronic systems. After a brief review of the basic features of silicones, this presentation will describe an entirely new family of silicone products. These new materials have been specifically designed to meet the increasingly stringent requirements imposed upon electronic systems for the automobiles of the eighties especially for under bonnet mounting. The new HIPEC self priming silicone elastomer range includes high strength flexible adhesives for the assembly of dissimilar materials like Plastic to metal, a thermally conductive adhesive for compliant bonding of hybrid circuit substrates to their heat sinks and a high purity thixotropic coating for the protection of naked semiconductor chips and their bonding wires by a "blob" deposition. Comparisons with existing rigid products are discussed as well as dispensing techniques and application cases.
