3.1.4 Installing to the IC Socket

CAUTION

1. Check the location of pin 1 before insertion.

2. Use the provided screwdriver to tighten screws. Do not

use the screw (M2, 10mm) that are provided with the

cover for connecting the emulator.

3. The tightening torque must be 0.054 N⋅m or less. If

accurate measurement of the applied torgue is not

possible, stop tightening when the force required to turn

the screw becomes significantly greater than for the

initial tightening. If a screw is tightened too much, the

screw head may break or a faulty contact may be caused

by cracks in the IC socket solder.

4. If the MCU does not operate correctly, the solder might

have been cracked. Check conduction with a tester and

re-solder the IC socket if this is required.

Use the provided cover for connecting the emulator to fasten the user-system interface converter

board to the IC socket for a PLQP0176KB-A package on the user system. Apply vertical force to

fasten the parts together. Take particular care to align the positions of pin 1 and the guide pin and

to avoid the application of twisting force that might damage the soldered IC socket.
