The PGA Base can accommodate PGA packages up to 15 x 15 pin arrays.
The PGA Base contains a ZIF (zero insertion force) socket to hold the
PGA device and routes the signals from the compliant pins to the correct
socket pins. The PGA Base supports 28-, 44-, 68- 84-, and 88-pin PGAs.
Use the following procedure to insert a PGA device into the PGA Base.
Note: When you insert a PGA device into the PGA Base, pay particular
attention to the orientation and positioning of the device.
1. Install the PGA Base into PinSite. Unlock the PGA socket by lifting up
on the socket lever.
2. Insert the device into the PGA socket. Make sure the PGA device is
bottom justified and that pin 1 of the device is against the left side of
the socket. Figure A-11 shows the proper alignment of a PGA device.
3. Push the socket lever down to lock the PGA device into the PGA
socket.
