The Seiko Epson NS 6040 is a high-speed IC handler. The NS 6040 automatically transports semiconductor devices and classifies them according to inspection results. The NS 6040 is part of the NS-6000 series of high speed IC handlers from Seiko Epson.[1][2]

The Seiko Epson NS 6040 is a high-speed IC handler, a type of semiconductor test equipment used in the final test stage to automatically transport, position, and sort integrated circuits after electrical testing. Handlers of this class interface with an automated test equipment (ATE) system to move devices from input trays through test sockets and then into output bins based on test results.
IC handlers like the NS 6040 use a series of robotic arms and conveyors to pick devices from input trays, place them onto a shuttle or hot plate for temperature conditioning, then transfer them into test sockets where electrical contact is made with the tester. After testing, the handler unloads the device and sorts it into appropriate output trays based on pass/fail or bin categories. The system includes vacuum pick-and-place mechanisms, index arms, and multiple temperature zones for ambient and high-temperature testing.
