A Laser Focus World article covers the key process parameters for laser welding of Nitinol, including shielding gas delivery, heat control and post-weld treatment, along with methods for evaluating weld quality.
Focuslight addresses Mini and Micro LED process challenges through laser mass transfer, mass welding and chip repair, with key factors being spot control, energy uniformity and closed-loop temperature control. The Flux H system for mass welding uses a 4000-10000W, 976nm light source, with spot length and width adjustable in segments from 2 mm to 200 mm and energy uniformity above 97%. The Flux H system for chip repair uses a 30-150W, 976nm light source, with a 365um×105um spot and energy uniformity above 90%.
Why we recommend it: Mapping mass transfer, welding and repair to spot and thermal management requirements provides a concrete method for working backward from display manufacturing bottlenecks to laser system design parameters.
