ABSTRACT:
Integrated circuits (IC's) are stored for a time interval in a set of elongated guideways to bring them to a preselected temperature prior to testing. The guideways each hold a line of IC's in a loose end-to-end array. A frame carries the guideways. The frame and guideways rotate about a central shaft that is generally aligned with the guideways. The guideways are rotatably mounted in the frame and a gear system, preferably one carried on the frame and the guideways, ensures that as the frame rotates the guideways maintain the same angular orientation with respect to the horizontal. In the preferred form the guideways are generally tubular members with an upwardly facing open channel and an opposed, spaced apart rail that retain and guide the IC's. The entire frame and the guideways carried in the frame are inclined from the horizontal to provide a gravity feed of the IC's from one of the guideways located at an "unloading" position.
