Ultra Fine Pitch Bumping using e-Ni/Au and Sn Lift-off Processes
Keywords: flip chip, lift off, Electroless nickel
Wafer bumping is often separated into two different categories: flip chip bumping (FC) and wafer level chip scale packaging (WLCSP). This categorization and affiliated nomenclature is partially based on the solder bump size and the type of equipment used to create the bump.
