Removal Procedure
1. Remove processor heatsink retention mechanism.
2. De-solder the WSHS leads using a SMTC 104 tip. Use a small amount of solder to prime the tip
if necessary.
3. Stand the board vertically using jig (Figure 12).
4. Use a soldering iron with an STTC 137 tip to loosen WSHS pins and remove the heatsink.
Gently wiggle each lead loose while applying heat to lead.
5. Apply flux and remove any residual solder from each hole.
6. 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.
