Fastening Cable Head
1. Use a Phillips-type screwdriver whose head matches
the screw head.
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 cable head to the IC socket for an TFP-80C package on the user
system with the four screws (M2.6
be tightened a little at 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.
