Abstract: An in-circuit test fixture loader includes a carrier that is able to receive and support an in-circuit test fixture. The carrier includes a pair of opposing side rails and an end rail between the side rails. The side rails and the end rail are spaced to receive the in-circuit test fixture between the side rails and against the end rail. The loader also includes a fixture lock connected to the carrier to prevent movement of the in-circuit test fixture away from the end rail. A horizontal slider attached between the carrier and a mechanism base includes guide shafts that guide the carrier and the in-circuit test fixture in a first substantially horizontal direction. A vertical slider of the loader is attached between the carrier and the mechanism base. The vertical slider includes an actuator that is operable to slide the carrier and the in-circuit test fixture in a second substantially vertical direction between an upper position and a lower position.
