Section 3 Installing the MCU to the User System

1. Check the location of pin 1 before inserting.
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 a socket contact error may be caused
by a crack in the socket solder.
3. If the MCU does not operate correctly, cracks might have
occurred in the solder. Check conduction with a tester
and re-solder the IC socket if necessary.
Check the location of pin 1 before inserting the MCU into the IC socket on the user system, as
shown in figure 8. After inserting the MCU, put the socket cover on the MCU and the IC socket and
fasten it with the four corner tabs.
