Abstract:
1. Apparatus for testing a circuit on a substrate, comprising: a support frame; a transfer chuck to hold a first substrate; a thermal conditioning chuck capable of heating or cooling the first substrate while held by the transfer chuck; a test chuck located on the frame and being movable relative to the transfer chuck so that a surface thereof moves into contact with the first substrate, the first substrate being securable to the test chuck, the test chuck being movable relative to the transfer chuck so that the first substrate moves off the transfer chuck and to the test chuck, and the test chuck including a lower portion and an upper portion, wherein the upper portion is disengageably secured to the lower portion and wherein the first substrate is secured to the upper portion; an image recordation device located in a position over the substrate as it moves off the transfer chuck so as to record an image of a surface of the first substrate while it moves off the transfer chuck; and a plurality of contacts secured to the support frame, the test chuck and the contacts being movable relative to one another so that the contacts contact terminals on the first substrate; and an electric tester connected to the contacts so that signals can be relayed through the terminals and the contacts between the electric tester and the circuit.
