  • Method of influencing the contact angle of the nozzle surface of inkjet printheads
    Patent number: 5633664
    Abstract: Molded inkjet modules having still closed nozzles are coated with a polymer solution, preferably a PEEK solution. By means of Eximer laser radiation of a definite wavelength the nozzle ports extending through the PEEK layer and the layer of channel formation material (14 and 16) are formed by application of the laser ablation mask process. Then the surface of the PEEK layer is irradiated with a considerably reduced laser intensity (11) using the same wavelength as in the ablation process. The desired contact angle can be set in response to the irradiation.
