Bed of Nails Fixture

Bed of Nails Fixture

This bed of nails fixture allows the 7-up panelized PCB assembly (not shown) to be installed with open access.  The PCBA is installed and aligned via 2 tooling pins.  With a single hand, the operator flips the lid down, lowers the entire carriage into the bed of nails, and locks the carriage in place (the reverse can also be done with a single hand).  This design permits easy access for PCBA installation/removal while avoiding “scrubbing” of the pogo pins against the PCB test pads. Pin landing is repeatable to within an 0.008” diameter region.

Surya Design handled the mechanical design of this fixture.
