ABSTRACT:
A system for calibrating the input tray of an integrated circuit handling device for temperature. The system includes a plurality of fixed sensors mounted at locations along the input tray of the handling device. The fixed sensors serve to sense temperatures within defined zones corresponding to the locations at which the fixed sensors are positioned. Various heaters are also included, and these heaters adjust temperature within the defined zones in response to temperature readings sensed by the fixed sensors. Each of a plurality of thermocouple sensors is received within an integrated circuit body. Such an IC body-carried thermocouple sensor is positionable at a location along the input tray of the handling device at a location closely proximate the location of a fixed sensor. Such thermocouple sensors serve to sense the actual temperature to which an IC passing along the input tray would be exposed as it passes through a zone defined by a corresponding fixed sensor. An automatic processor is included, the processor being programmed to receive information from the thermocouple sensors and to adjust the stated sensed temperatures of corresponding fixed sensors to correspond to actual temperatures sensed by the thermocouple sensors.
