Renesas H8/3644 Series - Manual (Page 13)

Fasten the user system interface cable head to the IC socket for an TFP-80C package on the user
system with the four screws (M2.6
x 12 mm; with four 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.
