In one aspect, a method of establishing thermal contact between a first semiconductor chip and a heat spreader is provided. When a micro-type base station receives an EVDO access request containing an IMSI of the requesting access terminal, the micro-type base station will use the included IMSI to establish and identify a data connection to a PDSN. , melts at lower temperatures compared to conventional glass, and can safely form the cover without damaging the LED element.
