2.1.4 Fastening IC Socket Connector
CAUTION
1. Use the screwdriver provided for tightening screws.
2. The tightening torque must be 0.294 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 on the user system with four screws
(M2
×
12 mm) provided.
Take special care, such as manually securing the IC socket soldered area, to prevent the soldered
IC socket from being damaged by twisting the components.
