Abstract:
A package structure comprising:a ceramic base having a top surface; an electronic component mounted on said top surface; a thixotropic silicone gel overlying said component; said component being connected by a conductive line to external terminal leads of a connector; and said gel having a thixotropy index of about 1.5-3.6, a penetration depth of about 6-10 mm, a viscosity of 1000-5000 mPaÂ·s at 25Â° C., a light transmittance greater than 60%, an exothermic peak at 100-140Â° C., a one-pack form of uniform mixture, and a rate of change in viscosity of no more than 10% of the initial value after standing for 7 days at 40Â° C.
