Abstract

A method of screen printing on low temperature co-fired ceramic (LTCC) is disclosed that comprises the steps of (i) aligning tape position on the printer table of a screen printer machine for precisely positioning the tape relative to the screen mesh of the screen having a plurality of pattern openings; (ii) adjusting screen printing parameter for setting a printing condition, wherein the squeegee speed is adjusted to 50-100 mm/s; squeegee pressure is 0.05-0.wopa15 MPa; and a gap between the screen and the tape is 0.8-1.0 mm; and (iii) optimizing the screen mesh parameter with stainless steel screen mesh, wherein the screen mesh of the screen is optimized at mesh tension of 22-28 N/cm; mesh angle of 22.5°; thickness of an emulsion of 0.044 mm; mesh wire diameter of 0.028 mm; and screen mesh count of 325 apertures per inch.
