2.1.3 Installing the IC Socket
CAUTION
Check the location of pin 1 before inserting.
After checking the location of pin 1 on the user system interface board and pin 1 on the IC socket
connector, align the guide pins on the IC socket connector with the guide holes on the user system
interface board, and insert the IC socket connector into the IC socket (figure 3).
2.1.4 Fastening the Cable Head
CAUTION
1. Use a 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 cable head to the IC socket for an PLQP0120LA-A package on
the user system with the four screws (M2.0 x 10 mm) provided. Each screw should be tightened a
little at a time, alternating between screws on opposing corners. Take special care, such as by
manually securing the IC socket soldered area, to prevent the soldered IC socket from being
damaged by overtightening the screws or twisting the components.
