Pallet conveyor systems require efficient methods to interface back to test systems and ECC fixtures are designed for that purpose. Pallet fixtures will consist of two mating fixtures, one affixed to each pallet and one attached to a slide or actuator that engages the pallet fixture when it indexes to the test station. The pallet fixture will have a set of solid contacts. The slide/Test Side fixture will incorporate spring probes that engage the solid contacts on the pallet fixture.
