Abstract
A method of fabricating a battery protection circuit package according to one aspect of the present invention includes forming a first mounting structure by mounting battery protection circuit elements on a printed circuit board (PCB), forming a second mounting structure by mounting the first mounting structure on a lead frame which comprises an input/output terminal portion for external connection and at least one metal tab for battery cell connection, forming an encapsulation structure by encapsulating the second mounting structure with a molding material to encapsulate at least a part of the battery protection circuit elements while exposing the input/output terminal portion and the at least one metal tab of the lead frame, and bonding at least one flexible printed circuit board (FPCB) to the input/output terminal portion of the encapsulation structure.
