A system for double sided integrated circuit device testing includes: (i) a picking section including: (a) a plurality of picking-section pockets; (b) a picking-section plate including: one or more picking-section pocket openings, and first and second picking-section plate pins; (ii) a placing section including: (a) a plurality of placing-section contactors; (b) a placing-section member including: one or more placing-section contactor openings, and first and second placing-section member pins; and (iii) a pick-and-place section including: (a) a pick-and-place device including: a plurality of pick-and-place head contactors, and one or more sets of actuators; and (b) a pick-and-place head plate including: one or more pick-and-place head contactor openings, each pick-and-place head contactor opening corresponding to a pick-and-place head contactor, and first and second spring-loaded bushings configured to engage with the first and second picking-section plate pins, and the first and second placing-section member pins.

Group vision alignment for double sided IC device testing

An apparatus comprises a cavity coupled to a pneumatic controller configured to control pressure in the cavity; a piston configured to be pulled into the cavity when pressure in the cavity is below atmospheric pressure and to be pushed outward when pressure in the cavity is greater than atmospheric pressure; and a gripper arm mechanically coupled to the piston. The gripper arm may be configured to support a device under test. The gripper arm may be coupled to the piston through a pusher bar. The apparatus may further comprise a pneumatic control port; and a pneumatic bleed port. The pneumatic control port is coupled to the cavity, and the pneumatic bleed port is configured to bleed pneumatic pressure to atmosphere if the piston over-travels a predetermined position.

Side gripping mechanism and device handlers having same

A method for sorting devices in automated handling equipment, including placing a plurality of input trays containing a plurality of devices and a plurality of empty trays into a handler; sorting the plurality of devices in the plurality of input trays into the plurality of empty trays according to a category of each of the plurality of devices, dynamically assigning categories to each of the plurality of empty trays for each category of the plurality of devices, dynamically assigning categories to the plurality of input trays and placing the sorted plurality of devices into the plurality of input trays, removing the empty trays housing the plurality of sorted devices from the handler and determining whether the sorting is completed.

Process for handling semiconductor devices and transport media in automated sorting equipment

A LED lighting system for reading multiple data matrix codes on device populated transport media with a line scan camera, includes a light housing, a plurality of LED circuit bars, having a plurality of LEDs, mounted to an inner surface of the light housing arranged to provide high angle lighting and low angle lighting and a light controller operatively connected to the light housing to selectively control the light intensity, the light distribution and the angle of the LEDs on each of the plurality of LED array bars, whereby the LED lighting system can reduce texture noise and detect contrast in color or contrast in texture on the device populated transport media. The LED lighting system includes a device cooling system having an air compressor for cooling the LEDs such that they can operate at an optimal level.
