IMPORTANT ELEMENTS IN FINE PITCH BONDING APPLICATIONS 

BOND PAD PITCH:

The distance between the centers of the bond pads.

BOND PAD SIZE:

May be square, rectangular, or round. The most important dimension is the size along the pitch, as shown above.

LOOP HEIGHT:

The most important aspect of wire loop height is the loop height directly adjacent to the capillary, if the capillary is designed to clear a maximum loop height that occurs away from the capillary, the "T" dimension will be less than required, resulting in a less than ideal second bond.

CLEARANCE:

The designed clearance between the capillary angle bottleneck and the adjacent wire tolerances, capillary manufacturing tolerances, loop control, and desired quality standards can all influence the designed clearance. The following tables were computed using 0.0005in./13 wire to angle bottleneck clearance (critical clearance shown above).

Dimensions in inches unless otherwise specified
