MICROINJECTOR NOZZLE PLATE ASSEMBLY AND METHOD FOR ITS MANUFACTURE Russian patent published in 2000 - IPC

FIELD: manufacture of device for jet printing. SUBSTANCE: template with a zone of holes is immersed in electrolyte, in which NiH₂|SO₃|H, NiCl₂, H₃BO₃, C₁₂H₂₅SO₄|NaS and deionized water are mixed in a preset proportion. After that current of a preset density is applied so as to form the nozzle plate, having a great number of holes. The nozzle plate thus obtained has a different degree of roughness on the inner and outer surfaces, which provides for elimination of cross distortions and air bubbling. EFFECT: facilitated procedure. 23 cl, 6 dwg
