This apparatus provides a means for automatically controlled removal of integrated circuit assemblies from a testing board or other surface where they have been undergoing quality control tests during the IC manufacturing process. The preferred procedure involves passing an inverted standard test board containing a plurality of standard IC assemblies attached thereto, in parallel rows, over a matching array of spring loaded, wedge shaped extraction fingers, which slide into parallel matching slots between the test board sockets and the attached IC assemblies to disengage and separate the IC assemblies from the test board. The loosened assemblies then drop into parallel, matching, down sloping storage reservoirs for transfer to carrier tubes. Misaligned or jammed assemblies displace the spring loaded extraction fingers axially, causing the particular fingers to activate an extraction finger position sensor which then stops the standard mechanical means that moves the test board over the extraction fingers. The displaced fingers are located by visual or other means, the defective assemblies are removed, the fingers return to their original positions and the test board assembly removal process continues to completion.

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.
