4.1.2 Installing Cable Head
CAUTION
Check the location of pin 1 before inserting.
If the IC socket is not connected properly, the power-supply
pins will be shorted as shown below.
180˚ rotation
55 (Vss)
127 (AVref)
Align pin 1 on the IC socket for a PLQP0144KA-A (FP-144LV) 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.
4.1.3 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.
