ABSTRACT:
A hold-down finger for holding a circuit board in a test fixture. The hold-down finger includes an attachment portion and a finger. The attachment portion is for attaching the hold-down finger to the test fixture. The attachment portion has a central axis. The finger is coupled to the attachment portion at a location displaced from the central axis of the attachment portion. Displacing the finger from the central axis allows for the tip of the finger to be located more precisely in a radial manner about the center point of the device to hold a circuit board down against the extreme pressures of test probe springs.
