Finish
5.3.1 The finish for applicable components shall be as specified herein or equivalent. The plug and
receptacle terminals shall be plated in the contact area to the minimum gold or palladium
nickel with gold flash plating thickness specified on product prints (over 1,27um/50u”
minimum nickel underplate). The plug and receptacle terminal soldertail section shall be
plated with 1,27um/50u” minimum tin as specified on product print (over 1,27um/50u” nickel
minimum underplate). The plug and receptacle press fit area shall be plated with 0,5um/20u”
minimum – 1,5um/60u” maximum tin (over 1,27um/50u” nickel minimum underplate). No
plating at cut-off point.
5.3.2 The metal hold down terminals for the plug and receptacle connectors shall be plated with
1,27um/50u” minimum tin as specified on product prints (over 1,27um/50um minimum nickel
underplate). No plating at cut-off point.
5.4
Design and Construction
Connectors shall be of the design, construction, and physical dimensions specified on the applicable
product drawing. The plug connector shall be a multi-piece assembly having single row of contacts in
the mating area which dividing into two signal segments (S1-S7, S8-S14) and power segment (P1-
P15) or either one which transition out to either surface mount style or solder style soldertail to
accommodate various P.C. board thickness. The contact pattern in the mating area will have short and
long terminals in a specific pattern that results in a 0.5mm (0,020’) differential between contact points
in the long and short terminals. (This allows for first mate-last break capability - see respective product
prints for location of short and long terminals.)
The receptacle connector shall be a multi-piece assembly having single row of contacts in the mating
area which dividing into two signal segments (S1-S7, S8-S14) and a power segment (P1-P15) which
transit out to a in-line or stagger through hole pattern or surface mount pad. The contact pattern in the
mating area will have short and long terminals in a specific pattern that results in a 0.5mm (0.020”)
differential between contact points in the long and short terminals. (This allows for first mate-last break
capability – see respective product prints for location of short and long terminals.) The receptacle hold
down terminal has the board retention features that secures the connector to the board in preparation
for solder reflow (through-hole) or board termination (press-fit or SMT).
A polarization peg (optional) on the bottom of the connector housing assures proper connector
orientation during board mounting. The receptacle through hole connector and press fit connector are
designed to terminate to board thickness of 1.57mm (0.062”), 2.36mm (0.093”) and 3.18mm (0.125”).
Visual examinations of connectors are to be done per EIA 364-18.
5.4.1 Mating. The connectors shall be capable of mating and unmating manually without
the use of special tools.
5.4.2 Workmanship. Connectors shall be uniform in quality and shall be free from burrs,
scratches, cracks, voids, chips, blisters, pin holes, sharp edges, and other defects that will
adversely affect product’s life or serviceability.
