Title:
BASE RESIN FOR SOLDERING FLUX, SOLDERING FLUX AND SOLDER PASTE
Document Type and Number:
WIPO Patent Application WO/2013/172295
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a novel base resin for a soldering flux, said novel base resin being capable of improving the fluidity of a flux, the viscosity stability and tackiness of a solder paste, and the color tone and crack resistance of a flux residue. This novel base resin comprises a rosin (A) containing: at least 15wt% of a pimarane-type resin acid (a-1); at least 1wt% of a labdane-type resin acid (a-2); and at least 50wt% of an abietane-type resin acid (a-3) that does not have any conjugated double bond.
