We believe panel is a way to solving the large area AI chip, right, packaging with HBM together. So all the wafer level is a lot of, I call the area. So with the efficiency of the using the area. So panel packaging, one key is plating technology, right? I should say a lot of people in the copper plating for panel is a vertical style. And we are probably the first one to propose the horizontal and cover plating for the panel, which also we got the 3D Insight award, Innovation Technology award from USA. We believe we really have a good solution and they can play their panel uniformly and there will be a fill requirement of all this either 310×310 or 515×510.

By the way, we’re going to ship one of the panel plating tool in the fourth quarter. And also, we’re engaging with multiple customers for the panel packaging business in Taiwan and U.S. and also in China — Mainland China.”
