WSHS Removal and Installation Procedure
Two methods exist for WSHS removal, lead clipping or de-soldering. Re-installation of the heatsink
for rework or metrology purposes includes a single method.

55-degree angle clippers (Figure 10)
•
Solder wicking kit
Figure 10. 55-Degree Angle Clippers
Removal Procedure
1. Remove processor heatsink retention mechanism.
2. Cut the WSHS leads using the 55-degree angle clippers. To reduce potential of damaging board
and components, cut the leads in the order shown in Figure 11.
3. Flip the board over and remove the leads, using tweezers and a soldering iron with a STTC 137
tip.
4. Apply flux and remove any residual solder from each hole.
5. Inspect the board and ensure all holes are clean and completely free of solder. Make sure none
of the adjacent components were damaged during the removal process.
