METHOD OF MAKING A MATRIX PRINT HEAD

摘要

The method for fabricating a matrix print head for use in nonimpact electrolytic printers involved stacking and laminating green ceramic sheets (11) having holes (12) filled with conductive paste to form electrodes (13) then embossing the top ceramic sheet (11) with insulators (14) and screening the same with a layer (15, 16) of ruthenium dioxide. The assembiy is then sintered at less than 1000 DEG C and the resulting structure smoothed by lapping and finished in a convention fashion.
