FINE PITCH BONDING TOOL FOR CONSTRAINED BONDING |
| 摘要 |
<p>PURPOSE: A fine pitch capillary bonding tool is provided to make ball bonds having a consistent bonded ball size even though the air balls may vary in diameter. CONSTITUTION: A fine pitch capillary bonding tool for constrained bonding comprises a novel ball constraining recess (24) in the working tip (16). The ball being bonded extrudes vertically into the constraining recess without lateral extrusion which would create mashed balls of varying diameter. When an air ball is bonded it is forced into the constraining recess which has a shoulder portion (26) for exerting a downward bonding force.</p> |
