3.1.5 Mounting MCU on the IC Socket

CAUTION

1. Check the location of pin 1 before insertion.

2. Use the screw (M2, 6mm) and screwdriver provided with

the IC socket to mount the MCU in the IC socket.

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

accurate measurement of the applied torque 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.

When mounting the MCU in the IC socket on the user system, confirm that pin 1 of the MCU is in

the correct position and then fasten the cover with screws. Use the cover provided 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. 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.
