Abstract
A device to access and/or verify connections between a chip package and a printed circuit board ('PCB'), specifically within packages lacking back-side measurement access, includes a housing for insertion between the chip package and PCB. A passageway in the housing connects an entrance and an exit from the housing. The entrance is disposed on an end of the housing facing away from the chip package. The exit is disposed on a side of the housing below the chip package such that the passageway is directed at a signal path between the chip package and the PCB. A conductor disposed in the passageway is movable between a retracted position in which a contact end of the conductor is disposed within the passageway of the housing and an extended position in which the contact end of the conductor is disposed outside of the housing and in contact with the signal path.
