ABSTRACT:
Disclosed are a method for manufacturing a laminated lead frame and a laminated lead frame manufactured thereby, wherein lead frame single plates to be laminated one on top of the other can be reliably bonded together with a relatively light load. Under the method for manufacturing a laminated lead frame by means of stacking and bonding lead frame single plates10and11, each of which has been processed into a predetermined shape, a plurality of protuberance sections12are formed in at least one of mutually-opposing surfaces of the lead frame single plates10and11that vertically pair up with each other. The mutually-opposing lead frame single plates11, 12are bonded together via the protuberance sections12.
