NOTES
1. Cautions regarding printed circuit
board fabrication
1) Appropriate dimensions for the board
insertion width should be provided for the
connector connection section of the
printed circuit board. If the clearance
between the printed circuit board
insertion width and that of the connector
is large, defective contact or short circuit
can be caused. The drawing for the
printed circuit board pattern design
should provide reference to the clearance
as being small.
2) The pattern shift of the front and back
connector connection section of the
printed circuit board should be within
0.2mm.
3) Bevelling should be provided without
fail for the insertion width of the
connector connection section. When the
printed circuit board is inserted in the
connector, the bevelling will keep
distortion of the contacts and insertion
force small, improving the insertion
capability along with preventing defective
contact due to dropping out of the printed
circuit board end surface.

4) The proper thickness of printed circuit
board should be used.
5) Care must be taken with printed circuit
board “warp.” The extent of the warpage
may be exacerbated when the electronic
components are mounted on the printed
circuit board due to the contraction of the
solder on the board. For this reason,
ensure that the maximum warp of the
area where the connector is mated is
0.1mm.
2. Regarding insertion of printed
circuit board
1) Care should be taken to avoid having
any oil, flux, or other foreign matter
adhere to the insertion section contact
surface of the printed circuit board.
Foreign matter can lead to defective
contact. If such a condition exists, the
adhering matter should be removed with
alcohol, freon, or other suitable solvent.
2) Insert into connector at least 8.2 mm
from the insertion edge of the PC board.
3) By means of a groove fabricated at a
designated position, a key (special
accessory part) is inserted for the
prevention of reverse insertion or
incorrect insertion of a similarly
appearing printed circuit board.
