Abstract

This is apparatus for unplugging the bonding tip 13 of a capillary bonding tool 12. Unplugging punch 9, with punch tip 14 attached thereto, rides axially in v-bearings 15 and 16. Belt 8 holds punch 9 within the V bearings, and in contact with depth adjustment screw 7. Lower slide 2 is mounted to base 1, and its position adjusted by lower lead screw 10 to bring the tip 13 of tool 12, which is held in magnetic mounting pad 11, into partial alignment with punch tip 14. Upper lead screw 5 rotated upper arm 3 with respect to stop 4 about base rod 17 to complete alignment of tips 13 and 14. Lever 6 is actuated to force punch tip 14 into bonding tip 13 to remove the wire or material which plugs the latter.

Capillary Unplugging Tool

This is apparatus for unplugging the bonding tip 13 of a capillary bonding tool 12. Unplugging punch 9, with punch tip 14 attached thereto, rides axially in v-bearings 15 and 16. Belt 8 holds punch 9 within the V bearings, and in contact with depth adjustment screw 7. Lower slide 2 is mounted to base 1, and its position adjusted by lower lead screw 10 to bring the tip 13 of tool 12, which is held in magnetic mounting pad 11, into partial alignment with punch tip 14. Upper lead screw 5 rotated upper arm 3 with respect to stop 4 about base rod 17 to complete alignment of tips 13 and 14. Lever 6 is actuated to force punch tip 14 into bonding tip 13 to remove the wire or material which plugs the latter. The apparatus unplugs the fine hole in a capillary bonding tool used in ultrasonic or thermo-compression methods of connecting a very thin gold or aluminum wire from the tiny chips or dies to the heavier leads of an electronic package.
