摘要

Silicones have been used in the electronics industry as protective/assembly materials for operations that will have a wide temperature variation. A large variety of silicone products are available to satisfy the needs for the majority of these operations, including: coatings, adhesives and encapsulants. Special kinds of encapsulants, subject matter of this study, are the gels. Silicone gels are a special kind of encapsulating materials with unique characteristics. They are extremely soft elastomers (solids with liquid characteristics) that are used to provide high levels of stress relief to sensitive circuitry when operating at adverse environments. They provide protection by functioning as dielectric insulators, forming environmental barriers and relieving mechanical and thermal stress on components. Advances in miniaturization technologies have had dramatic impacts on our lives. Radios, computers, and telephones that once occupied large volumes now fit in the palm of a hand. This miniaturization has brought the need to use more delicate components/circuits that have to work in harsh environments and withstand exposures to high or low temperatures. Silicone gels are products that gather many of the special requirements to protect these sensitive assemblies working in a highly demanding environment. The purpose of this paper is to explore the performance of silicones gels when operating at high or low temperature to better establish the reliability temperature limits for these kinds of products.
