5.2 Glossary of Terms:
Backup
(or Support)
Pallet
A simple fixture used to locate and support a printed circuit while a compliant
pin connector is being pressed into the pc board. Considerable force is required
to press one of these connectors into a pc board, thus the pc board must be
adequately supported to avoid being damaged. It must have adequate clearance
for the terminals when they protrude through the pc board.
Compliant Pin
Connector
A connector which has terminals that are designed to give slightly when pressed
into a hole in a pc board so that the terminal (pin) makes solid electrical contact
with the printed circuit board, alleviating the need for soldering.
Flat Platen Press
A press in which the upper tooling or die set is not attached to the press ram.
The ram has a simple flat plate (or platen) attached to it. For this application, the
upper tooling is positioned in the connector(s). The press ram comes down on
top this tooling and presses on it. When the press ram goes back up, the upper
tooling stays with the connector.
PCB
Abbreviation for printed circuit board
Upper Tooling
The tooling that goes on top of the connector. It contains the mounting block
and dies (or tools) necessary to properly apply pressure where required to push
the connector’s compliant terminals and locking posts into the holes in the printed
circuit board.
