Tab tape, tab tape package and method of bonding same.

摘要

A TAB tape 10 comprises an insulating tape having a multiplicity of openings 12 (Figure 2), each surrounded by metallic leads 14 having inner lead portions 18 projecting into the opening 12. In the corners of the opening 12 on the tape are formed metallic chip pressure members 30 having tips 32 projecting into the opening 12 between groups of inner lead portions 18. A chip 24 is positioned in each opening 12 in turn with chip pads 26 aligned with the inner lead portions 18. A bonding tool 34 is moved downwardly into engagement with the inner lead portions 18 to force them into contact with the chip pads 26 and to thermocompressively attach them thereto. The corners of the tool 34 engage and bend the tips 32 into engagement with the surface of the chip 24, so that when the tool is lifted tie chip is prevented from following due to adhesion of the tool and leads.
