Abstract
The present disclosure relates to a molded radiofrequency, ‘RF’, power package. The present disclosure further relates to a method for manufacturing such package. According to example embodiments, weakening structures are provided in the leads to allow the leads to be bent without causing delamination in the body of solidified molding compound
Claims24
A molded radiofrequency, ‘RF’, power package, comprising:
- a heat-conducting substrate having a first surface and an opposing second surface, wherein the second surface of the heat-conducting substrate is exposed on a backside of the package;
- a semiconductor die having a first side and a second side, the semiconductor die being arranged with its first side on the first surface of the heat-conducting substrate, said semiconductor die having an RF power transistor integrated on its second side;
- a plurality of leads;
- a body of solidified molding compound that fixedly connects the heat-conducting substrate to the plurality of leads by directly adhering to the plurality of leads and the heat-conducting substrate;
- a lid fixedly connected to the body of solidified molding compound;
- wherein each lead comprises a first lead end, an opposing second lead end, a first segment connected directly to the first lead end, and a second segment connected directly on one end to the second lead end and on an opposing end to the first segment;
- wherein the RF power transistor is connected to the first lead ends of the plurality of leads using a plurality of bondwires;
- wherein, for each lead, the first and second segment fully extend inside and outside the body of solidified molding compound, respectively;
- wherein the second segments of the plurality of leads are bent or configured to be bent thereby dividing each second segment in:
- a first sub-segment extending substantially parallel to the heat-conducting substrate and away from the body of solidified molding compound;
- a curved sub-segment;
- and
- a second sub-segment extending obliquely relative to the first sub-segment and connected to the first sub-segment through the curved sub-segment;
- wherein the leads each further comprise a weakening structure arranged at least partially in the curved sub-segment, the weakening structure comprising at least one of a recess in or hole through the lead.
