The coplanarity of the SMT solder area lead is
maintained at the high accuracy of less than 0.1mm.
The very small and guide rib is provided, and secures
±0.6mm self-alignment, considering the mating
operativity into accounts. ( fig.1 )

Mis-insertion Prevention
q
Two-piece Connection Product
The boss prevents mis-insertion in the board to cause
due to the boss position and boss diameter.
In order to enhance the mating reliability for fine pitch
connector using two-pieces, the two-pieces of
connectors are combined by our unique method, and
can secure the mount position accuracy. In such a
new concept, the two-piece connected product is
prepared at every number of contacts ( The standard
mating pitch for the two-piece interconnected product
in two rows is 11mm. )

To match 100 ohm differential impedance and to reduce crosstalk, a staggered GSGSG pin assignment is recommended for
FX8C of 5mm to 9mm height, and a staggered GSSG pin assignment is recommended for 10mm to 16mm height. (G=ground
and S=signal)
