ABSTRACT:
The inventive apparatus is to provide rapid, automatic separation, classification and operator assisted dispensation of integrated circuit assemblies from burn-in and device under test boards to which they are attached. The apparatus is computer controlled, with an electronic control panel, and is assembled to differentiate between and separate physically acceptable and unacceptable integrated circuit assemblies and deliver, by means of a suitable reservoir, the acceptable assemblies to appropriate carrier tubes for further processing or shipping. The system uses an indexing table to move an inverted device under test board across an array of assembly extraction fingers which remove attached integrated circuit assemblies from the sockets of the test board and drop them into a reservoir. The reservoir is slotted to receive the individual assemblies and dispense them into carrier tubes. Several position sensing means are included in the system to provide automatic control of the indexing table, the assembly extraction fingers and the reservoir during the operation of the system.
