ABSTRACT:
An apparatus for facilitating the servicing of a printed circuit board which is removed from a support structure. An extender board is inserted into the space from which the board to be serviced is removed, and the extender board has zero-insertion-force connectors thereon to provide electrical connections to the board to be serviced. A collapsible support is used to support the board being serviced, and additional power connections are supplied to enable the board being serviced to maintain normal board-to-board signal flow while being examined outside of the support structure.
