Align pin 1 on the IC socket for a PRQP0064GB-A (former code: FP-64AV) 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.
3.1.3 Fastening Cable Head
CAUTION
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.
