Abstract:

A filament attachment system includes a bond head comprising a de-spooling system with a spool and balanced dancer arm assembly, a clamp having a curved filament entry, a narrower gripping region, and a wider filament exit, and a bond tool comprising a guide portion, a grooving portion, and a staking portion. The grooving portion forms a groove into a bond and the staking portion closes the groove over the filament, securing the filament in the bond. Thus, the filament can be attached with a single pass of the bond head using a single bond.
