MANUFACTURE OF INK JET PRINTHEADS

摘要

Ink jet printhead (8) components are formed initially by bonding together a grooved base wafer (10) and a suitable cover wafer (12), the area of the bonding wafer assembly being sufficient to provide a 14 x 14 array of components. Using a datum formation, the wafer assembly is divided into strips and linear processing steps are conducted, such as applying nozzle plates (14) and laser ablating nozzles. Each strip can then be divided to form separate printhead components.
