Small Bernoulli chuck for 5mm square wafers compatible with clean rooms.
Adopts a mechanism that discharges exhaust upward. It picks up and transfers surrounding chips non-contact without blowing them away with the ejected gas.
At Solar Research Institute, we have developed a "cleanroom-compatible small Bernoulli chuck" that non-contactly chucks and transports micro-work chips measuring 5.0 mm square and smaller. This device generates negative pressure through the ejector effect and Bernoulli effect by ejecting gas, as well as positive pressure through a pressure-type air cushion effect, allowing small cut wafer chips to be chucked in a non-contact state, floating in the air, and transported to a designated location. As part of this new mechanism, we have established a circuit to change the exhaust path around the suction pad, allowing for the alteration of the exhaust direction. Therefore, the exhaust does not blow away surrounding chips.
