3.6  About Evaluation Board 
When the evaluation board does not start operation after supplied power, check the following 
points. 
 
3.6.1  Contact failure of IC Socket 
Oscillation or thermal expansion may cause a poor connection between microcomputers and IC 
socket on the Evaluation Board.    Follow the steps below. 
 
Screw down the top cover of IC socket with setscrews at four corners. 
  
The tightening torque shall be 0.054 N.m. 
  
Note that only one tight setscrew may cause a poor connection. 
 
The IC socket included in the evaluation board uses NQPACK and HQPACK by TOKYO 
ELETECH CORPORATION.
