Abstract:
1. A method for manufacturing a plastic package base comprising: preparing a first lead frame including at least one first unit body comprising a first pad required for chip bonding and first leads acting as internal terminals, arranged around the first pad and spaced a predetermined distance away from the first pad; preparing a second lead frame including at least one second unit body comprising a second pad and second leads acting as external terminals and bonded to the first lead frame so that the second pad and the second leads correspond to the first pad and first leads of the first lead frame, respectively; attaching the first and second lead frames to each other so as to make the first leads and first pad of the first lead frame correspond to the second leads and second pad of the second lead frame, respectively; completing an integrated body consisting of the first and second lead frames having predetermined electrical and physical functions which a package must have, by removing unnecessary portions of the first lead frame; and forming a plastic body in empty spaces in the integrated body consisting of the first and second lead frames by a mold-shaping process.
