JOINT MATERIAL AND JOINT METHOD USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a joint material easily printing on a material to be jointed and capable of suppressing generation of non-sintered part in a joint part of materials to be jointed, and to provide a joint method using the same.SOLUTION: A joint material consists of a silver paste containing a silver fine particle which is coated by an organic compound having 8 or less carbon atoms such as hexanoic acid and has an average primary particle diameter of 1 to 50 nm, a silver particle which is coated by an organic compound such as oleic acid and has the average primary particle diameter of 0.5 to 4 μm, a solvent consisting of a primary alcohol solvent and a terpene alcohol solvent and a dispersant consisting of a phosphorous ester-based dispersant (or the phosphorous ester-based dispersant and an acrylic resin-based dispersant) with the content of the silver fine particle of 5 to 30 mass%, the content of the silver particle of 60 to 90 mass%, the total content of the silver fine particle and the silver particle of 90 mass% or more and a monocarboxylic acid-based sintering assistant having an ether bond is added.
