DESIGN AND CONSTRUCTION
The connector shall be a multi-piece assembly having two rows of contacts with surface mount
solder tail terminations and solderable surface mount retention devices for installation on surface
mount printed wiring boards or flexible circuits.
5.4.1
Mating. The connector shall be capable of mating and unmating manually without the
