| titleOfInvention | Soldering flux |
| abstract | An object of the present invention is to have high drying property in a heat treatment, good solderability, good wetting and spreading on a soldering surface, and no flash point, and uniform properties even when water is contained. Providing soldering flux with high electrical reliability. SOLUTION: An azeotropic mixture (A) containing a glycol compound (a1) having a boiling point of 120 to 200 ° C under normal pressure and water (a2) represented by the formula (1), and an activator (B) And the azeotropic point under normal pressure of the component (A) is 90 to 100 ° C. R 1 -O-[-CH 2 -CH 2 -O] n -R 2 (1) (n is 1 or 2; when n = 1, R 1 is H, R 2 is a C 1-4 alkyl group; When n = 2, R 1 is a C 1-3 alkyl group, R 2 is a C 1-3 alkyl group) 【Selection chart】 None |
