With the technology, obtained through the $25M acquisition of Uniqarta last February, K&S hopes to secure its roadmap and leadership in the back-end equipment market for LED-enabled backlighting. That speed is expected four years from now and is needed to cost-effectively produce a 4K television screen with 24 million self-emissive LEDs – the equivalent of filling an area the size of a soccer field with euro coins in 40 minutes. With parallelization, the laser technology even has the promise to gear up to 10,000 placements per second. This machine, the Luminex, uses laser-enabled advanced placement (LEAP) to shoot a thousand micro LEDs per second on a substrate. That’s the road taken by the first super-high-speed micro-LED assembly machine that was shipped by Kulicke & Soffa, most probably to Samsung. Researched at the University of North Dakota, engineered in Eindhoven. The company even expects that transfer speeds of 10,000 micro LEDs a second will be able to compete with lithography processes. With the first shipment of its Luminex platform, building on former Assembleon systems, Kulicke & Soffa underlines its commitment to the equipment market for advanced displays.
