ABSTRACT:
In a method for bonding bumps to leads by pressing leads installed on a carrier tape against bumps formed on a substrate, corresponding lead-bump pairs are individually bonded; particularly, one lead on the carrier and one bump on the substrate are first aligned, and then other pairs of leads and bumps are successively and individually bonded, thus performing a secure and uniform bonding action without necessity of alterations to the bumps.
