2.2.3 Inserting Cable Head

CAUTION

Check the location of pin 1 before inserting.

Align pin 1 on the IC socket for an TFP-144 package on the user system with pin 1 on the user

system interface cable head, and insert the user system interface cable head into the IC socket on the

user system, as shown in figure 4.

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.
