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-120 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 the screwdriver provided for tightening screws.
2. The tightening torque must be 0.098 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-120 package on the user
system with the four screws (M2
x 12 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.
