1. Insert alignment guide onto socket base using dowel pins.
Place alignment guide + socket base assembly onto target board.
2. Clean the PCB to remove grease, oil, and flux.
3. Align holes on alignment plate with four corner pads on target board,
hold socket base on to board tightly with finger and put a drop of super
glue on each corner. Let it dry, remove the alignment plate,
then run a bead of epoxy around socket base and let it cure until epoxy
is hardened. Recommended epoxy: EPO TEK 730.
Other equivalent epoxies can be substituted. Cure minimum 24 hours at
room temperature.
Note: Do not oven cure.
4. Place elastomer inside the socket base cavity (direction and orientation
are critical) as shown above.
5. Place ball guide inside the socket base cavity.
6. Place BGA package and compression plate into the socket base cavity.
7. Assemble socket lid onto socket base with socket lid screws.
8. Assemble compression screw into socket lid and gradually apply
1 in lb torque.
Primary dimension units are millimeters, Secondary dimension units are [inches], Weight is in grams.
Tolerances: Hole diameters ±0.03mm [±0.001"], Pitches (from true position) ±0.025mm [±0.001"], substrate thickness tolerance ±10%, all
other tolerances ±0.13mm [±0.005"] unless stated otherwise. Materials and specifications are subject to change without notice.
