摘要：A handler for handling semiconductor chips during a testing process includes aloading position at which packaged chips are loaded into a test tray, and an unloading
position at which the packaged chips are unloaded from the test tray. The test trayfollows a path through the handler from the loading position to the unloading position,and from the unloading position to the loading position. By separately performing theloading and unloading operations at these different positions within the handler,malfunctions in loading and unloading pickers that load and unload the chips may bereduced. Further, a malfunction in one picker performing one operation may be
prevented from influencing operations of the other picker performing another operation.Additionally, collision between the loading picker and the unloading picker may beprevented.
