Abstract: A test fixture for testing a head gimbal assembly having a flex circuit with a plurality of circuit pads, prior to installation of the head gimbal assembly into a disc drive. The fixture comprises a contact board having a plurality of electrically conductive contact points on a surface thereof, the contact points arranged to contact the circuit pads of the flex circuit. The fixture further comprises a clamp assembly connected to the contact board, the clamp assembly having an activation end, an opposite engagement end, and a pivot axis extending orthogonal to an axis defined by the activation end and the engagement end. The engagement end has a non-conductive engagement surface configured to contact the head gimbal assembly on a surface opposite the plurality of circuit pads.
