A sliding tray holder is coupled to an IC (integrated circuit) package test system having a plurality of test stations, for holding the trays of IC packages during testing of a high quantity of IC packages through the plurality of test stations. The sliding tray holder includes a platform for holding a first tray of untested IC packages and for holding a second tray of tested IC packages. Each untested IC package from the first tray of untested IC packages is loaded to at least one of the plurality of test stations for testing of the untested IC package such that the untested IC package becomes a tested IC package. The tested IC package is unloaded from one of the plurality of test stations to the second tray of tested IC packages. The platform holds the first tray of untested IC packages and the second tray of tested IC packages such that an operator does not hold the first tray and the second tray during loading of the untested IC packages to the plurality of test stations from the first tray and during unloading of the tested IC packages from the plurality of test stations to the second tray. A linear slide holds the platform and guides the platform holding the first tray and the second tray along the plurality of test stations as the platform is moved along the plurality of test stations during loading of the untested IC packages to the plurality of test stations from the first tray and during unloading of the tested IC packages from the plurality of test stations to the second tray. In this manner, the operator is relieved from constantly holding trays of IC packages during testing of a high quantity of IC packages.

An integrated circuit sorter automatically prevents the binning of a tested integrated circuit into a wrong container, such as a wrong tube, depending on the results of testing the integrated circuit. The automated integrated circuit sorter includes a respective switch for indicating that each output carries one of good or bad integrated circuits. A container identifier at each output identifies the type of container placed at the output. The container is determined to be for carrying good integrated circuits or bad integrated circuits. If the type of container placed at the output does not correspond to the type of integrated circuits at the output, then an integrated circuit stopper automatically blocks the admission of those integrated circuits into that container. The container identifier includes a light emitter and an optical sensor. A data processor determines whether a correct container or a wrong container is at the output. The data processor communicates with the integrated circuit sorter for affecting action of the integrated circuit stopper via the integrated circuit sorter. A data processor disable jumper may be coupled to the integrated circuit sorter to allow manual control of the integrated circuit stopper. Such a data processor disable jumper is especially advantageous in the event any component of the present invention is inoperative when the integrated circuit sorter may advantageously be manually controlled.
