Title:
THICK FILM COMPOSITION
Document Type and Number:
Japanese Patent JPH01262690
Kind Code:
A
Abstract:
PURPOSE: To realize a screen print having enhanced drying strength by dispersing a mixture of an electrical function material and pulverized particles of an inorganic binder into an organic medium. CONSTITUTION: A thick film composition for screen print is produced by dispersing a mixture of an electrical function material and pulverized particles of an inorganic binder into an organic medium. The organic medium is composed of 2-30wt.% of phenol based resin, 5-20wt.% or resin ester, 7-10wt.% of cellulose based organic polymer and a solution of organic solvent for dissolving them. The composition is then screen printed on a substrate in an arbitrary pattern and heated at 150-250 deg.C to cure the epoxy resin and evaporate the organic solvent. A thick film of cured epoxy resin is then fired in order to fire the resin and the organic polymer contained therein thus fusing and fluidizing the inorganic binder and compacting the electrical function material. The electrical function material includes resistor oxides (e.g. ruthenium based oxides) and resistor metals (Ag, Rd, etc.).
