Claim 0:
1. A robotic integrated circuit placement system, comprising:
a test board comprising a socket for holding an integrated circuit;
a tester coupled to said test board;
a chip tray having a plurality of slots for storing respective integrated circuits including said integrated circuit; and
a robotic arm system comprising:
a robotic arm having at least one stepper motor for controlling a position of an end of said robotic arm in X-, Y-, and Z-directions;
a top camera attached to said end of said robotic arm;
a bottom camera positioned between said chip tray and said tester; and
a controller coupled to said robotic arm and adapted to operate said robotic arm automatically, said controller performing image processing on images acquired by said top camera and said bottom camera and moving said integrated circuit between said chip tray and said socket using the robotic arm, determining at least one offset caused by slippage of said at least one stepper motor, and correcting said offset in response to said image processing.
