(1) Align the guides of CSSOCKET and LSPACK, and attach LSPACK to CSSOCKET.
(2) Place the guide plate (included with models released after November 2000) and spacer, in that order, on
LSPACK. Align the guide of the spacer with the component hole of LSPACK and the guide plate.
(3) Noting the position of pin 1 of the IC (BGA), gently place the IC from the top in the opening at the center of the
spacer, aligning it with the connector pin position.
(4) Place the top cover on the spacer. The holes at the four corners of the guide plate, spacer, and top cover must
match. Secure LSPACK and the top cover using the attached screws. Use a dedicated screwdriver to tighten the
screws. Hold LSPACK on the sides with your fingers, so that no stress is applied to the soldered parts of
LSPACK and CSSOCKET, and sequentially tighten the screws at the four corners. The tightening torque should
