Note:
Be sure to set up foot patterns for the
holders. Make the thickness and the
area of the solder-print screen thicker
and larger than the foot patterns
recommended so as to secure a
sufficient amount of solder applied.
(In carrying out manual soldering,
an amount of solder sufficient for
forming a larger fillet than that formed
at the time of reflow is required.)

: Pin number of the M3T-DUMMY80
: Pin number of the upper connectors
As the contacts of the IC
socket body touch the PC
board, thus be sure to give
special consideration to the
patterns of traces so that no
other pins touch the PC
board.
(Through-hole mounting is
not permitted.)
