Abstract:
A semiconductor package includes a leadframe forming a plurality of leads with a die attach site, a semiconductor die including a set of die contacts mounted to the die attach site in a flip chip configuration with each die contact of the set of die contacts electrically connected to leadframe via one of a set of solder joints, a set of solder joint capsules covering each of the set of solder joints against the leadframe, a clip mounted to the leadframe over the semiconductor die with a clip solder joint. The solder joint capsules restrict flow of the solder joints of the semiconductor die contacts in the flip chip configuration such that the solder remains in place if remelted during later clip solder reflow.
