Packaging structure and method for automotive components

摘要

The invention provides a packaging structure applied to an automotive component having semiconductors and electronic parts mounted on a ceramic base, characterized in that the semiconductors and electronic parts are partly or entirely sealed with a thixotropic silicone gel which has a thixotropy index of about 1.5-3.6 and a penetration depth of about 6-10 mm and a rate of change in viscosity of less than 10% of the initial value.
