The Wafer Loader mWL 150 / 200t is designed for fully automated loading and unloading of 150 / 200mm(6" / 8")thin - wafers from cassettes onto an external chuck for visual inspection.
The mWL 150 / 200t comes with a dual - arm - robot(with flip box optional),a combination of Bernoulli vacuum - and top grip end - effectors,two cassette stations with scanners,a pre - aligner,an end - effector change station,a transfer station(for storing a wafer while taking a different end - effector for further process)incl.an end - effector cleaner,as well as a touch screen.Optionally it can individually be equipped with a wafer flipping function and a customized external chuck.
The adaptation to OEM tools according to customer requirements is possible.
