Vertical-mount Miniature Ribbon connectors provide I/O directly from printed circuit boards, where the mating face of
the connector is in a plane parallel to that of the board.
Compliant-pin connectors terminate without solder to plated-through holes in printed circuit boards. The tail conforms
to the hole, providing a gas-tight termination without damaging the plating in the printed circuit board.
The seating cover acts as an insertion tool fixture, and must be left in place until the connector is installed on the
PCB. It may also be left on after insertion to serve as a dust cover to protect the connector from contamination.
See pages 6-51 through 6-53 for accessories such as bent bail latches and mounting screws that make the use of
Cinch Miniature Ribbon connectors even more cost-effective in board-mount applications.
