Abstract

An assembling mechanism locates and clamps a heatsink/cap assembly to a substrate in the following manner. The heatsink/cap holding fixture 1 is mounted on the surface of a movable table 2. The fixture is provided with locating pins 3 that properly orient the heatsink/cap 4 when pins 3 contact machined edges 5 of cap 4. A ram 6 is loaded with a holding band 7 and secured by means of pins (not shown) in groove 8 that are forced together by turning knob 9 of threaded screw 10. The ram 6 is lowered over cap 4, and jaws 11 of ram 6 grasp cap 4 when threaded screw 12 is turned by means of knob 13. The ram 6 is raised with holding band 7 and secured cap 4. The table 2 is indexed to the right after securing pin 14 is removed. When fully indexed to the right, securing pin 14 is re-inserted to hold indexing table 2 in correct position.

Heatsink/Cap Assembly Clamping Tool

An assembling mechanism locates and clamps a heatsink/cap assembly to a substrate in the following manner. The heatsink/cap holding fixture 1 is mounted on the surface of a movable table 2.

The fixture is provided with locating pins 3 that properly orient the heatsink/cap 4 when pins 3 contact machined edges 5 of cap 4. A ram 6 is loaded with a holding band 7 and secured by means of pins (not shown) in groove 8 that are forced together by turning knob 9 of threaded screw 10. The ram 6 is lowered over cap 4, and jaws 11 of ram 6 grasp cap 4 when threaded screw 12 is turned by means of knob
13. The ram 6 is raised with holding band 7 and secured cap 4. The table 2 is indexed to the right after securing pin 14 is removed.

When fully indexed to the right, securing pin 14 is re-inserted to hold indexing table 2 in correct position. The ram 6 is positioned over substrate 15 which is held by a substrate-locating fixture 16.

The fixture 16 properly orients substrate 15 in the desired position by means of locating posts 12 which engage tabs (not seen) on substrate 15 on two sides. The ram 6 actuates downward on a Z axis, rapidly at first and then at a controlled rate to accommodate different sized substrates. The traverse is controlled by a microprocessor. When ram 6 comes to a rest, spring-loaded screws 17 of holding band 7 line up with threaded holes 18 and are assembled. After the heatsink/cap assembly is secured to the holding fixtu...
