Impressive! Silly question, perhaps, but will such packages be available for PCB assembly by "retail" companies like PBCway, JLCPCB etc?
Also, is it even safe/practical to use WCSP on a PCB if the bare die is exposed to the environment? Or do they require conformal coating (or even epoxy potting?) after assembly to avoid premature faults?
