white-light-interferometry (WLI) measuring principle
white-light-interferometry (WLI) • measurement uncertainty ~ 1µm: independent from aperture, distance, material • coaxial optics: measurement in deep boreholes possible • all types of surfaces (smooth, rough, volume scatterers, …) • up to 4 Mio data points • Field up to 110 mm advantages
KORAD3D-L • area: 55x55 mm² • lat. Res.: up to 30 µm • camera: up to 3 MPix • uncertainty: ~ 1µm • speed: up to 500µm/sec white-light-interferometry (WLI)
WLI – applications • offline system – production line • FoV 3 x 3 mm² • Ø = 3mm, depth = 45mm • measuring of cone angles • high precision ( = 0.02°) injection nozzle
WLI – applications • inline system – 24/7 • FoV 13 x 13 mm² • dimensions of bumps (coplanarity) • warpage • high-speed (1 sec) bumps and solder paste (electronics)
WLI – applications • inline system • FoV 15 x 15 mm² • flatness <1 µm • measuring time: 5 sec. sealing surfaces
WLI – applications rotary valve • semi-automatic system • Close to the production line • FoV 50 x 50 mm² • flatness 5 µm • step height 15-20 µm
