GAISER CAPILLARY INFORMATION

20. IMPORTANT ELEMENTS PAGE 2 (2)

PITCH, PAD, SIZE, LOOP HEIGHT, WIRE DIAMETER 

The following tables show the maximum wire loop height that may be used with a known Capillary "T" size at a known bond pad pitch. The tables have been calculated for 0.0005in./13 micron clearance between a 10 angle bottleneck and the adjacent wire loop for 0.0010in./25 micron and 0.0013in./33 micron wire.
Bonding with higher loop heights (or larger T sizes) may be attempted with highly accurate bonders, or if minor touching of the loops by the capillary is acceptable.

A helpful ratio to use in planning in conjunction with the clearance tables is that for each additional 0.0010in./25 micron of loop height, the distance between the 10 angle bottleneck and the wire closes by 0.0001in./2.5 micron.
Example: Per the table a 10 angle bottleneck capillary with a T=0.0060in. used in 0.0050in. pitch, 0.0010in. wire bonding situation will have 0.0005in. clearance with a 0.011in. loop. If the loop height were increased to 0.014in. the wire to capillary clearance would be reduced to 0.0002in.
