2.2.4 Fastening 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 a TFP-100G package on the user

system with the four screws (M2

x 10 mm; with flat washers) provided. Each screw should 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.
