Abstract

This apparatus removes the module substrate from its packaging without causing damage to its mechanical or electrical properties. The apparatus 5 is mounted on a vertical slide 6 that is moved up and down by an air cylinder 7. It comprises a horizontally mounted vacuum chuck 8 with a center opening 9 for vacuum and with four small air cylinders (1, 2, 3 shown) positioned at each corner aligned with corner tabs 10 on the module cover 11. As the lifter assembly 12 is lowered, extended plastic piston tips 13 come in contact with the tabs 10 and slow the decent of the lifter 12. Since their cylinder pressure is less than that of the vertical slide cylinder 7, the piston rods of the four cylinders are forced to retract as the lifter 12 comes in contact with the substrate 20.

Module Disassembly Tool

This apparatus removes the module substrate from its packaging without causing damage to its mechanical or electrical properties. The apparatus 5 is mounted on a vertical slide 6 that is moved up and down by an air cylinder 7. It comprises a horizontally mounted vacuum chuck 8 with a center opening 9 for vacuum and with four small air cylinders (1, 2, 3 shown) positioned at each corner aligned with corner tabs 10 on the module cover 11. As the lifter assembly 12 is lowered, extended plastic piston tips 13 come in contact with the tabs 10 and slow the decent of the lifter 12. Since their cylinder pressure is less than that of the vertical slide cylinder 7, the piston rods of the four cylinders are forced to retract as the lifter 12 comes in contact with the substrate 20. After contact, vacuum is applied which draws the lifter 12 to the substrate 20. The fixture 14 is rotated, and the module screws removed. The fixture is then rotated back to its original position. The substrate 20 and base plate 21 are raised as the four cylinders push down against the module cover tabs, leaving the hat assembly behind. The operator removes the cover and replaces it with a tray. The lifter 12 lowers and deposits the substrate onto the tray and then moves up out of the way. The substrate now in the tray can be safely removed by the operator.
