Achieved in mounting φ30μm solder balls on
φ12 Wafer for the first time in the world

For the first time in the world, we have achieved in mounting a solder ball under the conditions of φ30 μm diameter / 50 μm pitch for φ12 wafer.

With the spread of remote work and the rise of big data / AI technology,
the amount of data processing has increased explosively.

And as processing speeds are required more than ever, it is expected to be used for increasing cutting-edge CPUs and for ultra-fine, high-density mounting of advanced logic such as graphics / AI chips
