Abstract

Official abstract text for this publication.

A resin composition having an adhesive property in a high temperature range that is estimated during soldering, and flux using this resin composition, a flux residue of which is washable. The resin composition contains a hydroxyl carboxylic acid having two or more carboxyl groups and a hydroxyl group in its molecule and a thermosetting resin in a ratio of 1:3 or more and 1:7 or less. Further, the flux contains the hydroxyl carboxylic acid having two or more carboxyl groups and a hydroxyl group in its molecule in an amount of 8.5% by mass or more and 16% by mass or less, and a thermosetting resin in an amount of 50% by mass or more and 60% by mass or less, wherein a ratio between the hydroxyl carboxylic acid and the thermosetting resin is 1:7 or less.

First claim

Opening claim text (preview).

The invention claimed is: 1. A resin composition, consisting of: a hydroxyl carboxylic acid having two or more carboxyl groups and a hydroxyl group in its molecule; and an epoxy resin in a mass ratio of 1:3 through 1:7, wherein the epoxy resin is contained in an amount of 75% by mass through 87.5% by mass based on the total mass of the resin composition. 2. A flux, consisting of: a hydroxyl carboxylic acid having two or more carboxyl groups and a hydroxyl group in its molecule in an amount of 8.5% by mass through 16% by mass based on the total mass of the flux; an epoxy resin in an amount of 50% by mass through 60% by mass based on the total mass of the flux; a hardening accelerator; and a solvent, wherein a mass ratio between the hydroxyl carboxylic acid and the epoxy resin is 1:3.75 through 1:7. 3. The flux according to claim 2 , wherein the hydroxyl carboxylic acid is any of tartaric acid, malic acid, citric acid and hydroxymalonic acid. 4. The flux according to claim 3 , wherein the epoxy resin is tris-(2,3-epoxypropyl)-isocyanurate. 5. The flux according to claim 2 , wherein the epoxy resin is tris-(2,3-epoxypropyl)-isocyanurate.
