THICK-FILM RESISTOR COMPOSITION FOR FORMING THERMAL TRANSFER TAPE, THERMAL TRANSFER TAPE WHERE IT IS PASTED TO BASE FILM, AND METHOD FOR MANUFACTURING THICK-FILM RESISTOR USING THE THERMAL TRANSFER TAPE

摘要

PROBLEM TO BE SOLVED: To provide a technology, wherein a thick-film resistor of arbitrary resistance value and shape is obtained without trimming being required as such resistance value as decided according to the length, width, and thickness the resistor can be corrected and selected. ;SOLUTION: A thick-film resistor composition for forming a thermal transfer tape comprising an organic vehicle which comprises mixed inorganic powder of 54-76 wt.% comprising glass powder, whose conductive component is ruthenium oxide and/or ruthenium pyrochlore oxide powder with main component being Pbo, SiO₂, and Al₂O₃, a resin binder of 14-23 wt.%, and organic solvent 10-23 wt.%, is coated on a base film of polyethylene terephthalate, then a contained organic solvent is dried and removed for manufacturing a thermal transfer tape for forming a thick-film resistor with a thick-film resistor layer of a specified thickness being stuck. For an obtained transfer tape, a base film part corresponding to a thick-film resistor shape selected with respect to an insulating substrate is heated to melt a part of a thick-film resistor layer, which is thermally transferred to the insulating substrate for sticking, and is sintered so as to form a thick-film resistor.;COPYRIGHT: (C)1999,JPO
