Installing Cable Head
Check the location of pin 1 before inserting.
Align pin 1 on the IC socket for a PLQP0100KB-A package on the user system with pin 1 on the
user system interface board, and insert the user system interface board into the IC socket on the
user system, as shown in figure 4.

Fastening Cable Head
1. Use a Phillip-type screwdriver whose head matches the
screw head.
2. The tightening torque must be 0.054 N•m or less.
If the applied torque cannot be accurately measured,
stop tightening when the force required to turn the screw
becomes significantly greater than that needed when first
tightening. If a screw is tightened too much, the screw
head may break or an IC socket contact error may be
caused by a crack in the IC socket solder.
3. If the emulator does not operate correctly, cracks might
have occurred in the solder. Check conduction with
a tester and re-solder the IC socket if necessary.
Fasten the user system interface board to the IC socket for a PLQP0100KB-A package on the user
system with the four screws (M2.0
a time, alternating between screws on opposing corners. Take special care, such as manually
securing the IC socket soldered area, to prevent the soldered IC socket from being damaged by
overtightening the screws or twisting the components.
