Automatic sealing is enabled through the use of an integrated annular-plate stiction valve which greatly reduces device footprint over in-plane configurations. We achieve automatic wafer-level liquid … WebbThe theoretical plate number (N) usually is expressed by one of two equations [9]: (Equation 8-2)N = 16⋅(tRwb)2 or (Equation 8-3)N = 5.545⋅(tRwh)2 where tRrefers to the … mckennon wimberly married
