In a method of manufacturing an ink jet print head that includes a number of aligned modules, an alignment mark is foamed on a first and a second adjacent module, wherein the alignment mark is positioned on a boundary between the first and the second adjacent module along which the wafer is to be separated. In a separating step the wafer is separated into separate modules such that the alignment mark is divided over said first and second adjacent module. At least one of said first and second module is aligned by reference to the divided alignment mark The method improves the accuracy, with which the modules can be aligned.
