Abstract

In many programs, it is critical to have the ability to quickly and reliably probe various Input/Output (I/O) points on a card. It is often necessary to probe these points while in the card's actual environment. Currently, the only way to access these signals is to attach an expensive high density permanent connector. This is a large overhead expense for any high volume program because only a small percentage of the card will require this type of testing. This interface provides a quick and reliable, mechanical and electrical connection. It is removable and completely reusable. It eliminates the need for an expensive high-density permanent connector.

Removable High-Density Connector Interface

      In many programs, it is critical to have the ability to quickly
and reliably probe various Input/Output (I/O) points on a card.  It
is often necessary to probe these points while in the card's actual
environment.  Currently, the only way to access these signals is to
attach an expensive high density permanent connector.  This is a
large overhead expense for any high volume program because only a
small percentage of the card will require this type of testing.  This
interface provides a quick and reliable, mechanical and electrical
connection.  It is removable and completely reusable.  It eliminates
the need for an expensive high-density permanent connector.

      The Removable High-Density Card Test Interface electrically and
mechanically connects any type of test equipment to the card edge.
It provides a solid high density connection for high frequency
signals.  It can be installed onto the edge of a card in a matter of
seconds.  It is self aligning and uses spring loaded probes to
contact the vias.  It can be customized to each individual
application using various connectors and any configuration of vias.
The example used is a 4 x 20 via configuration and a right angle
connector.
