Soldering flux preventing agent for printed wiring board and soldering method using the same |
| abstract |
(57) [Summary] [Purpose] Development of a flux bleed preventive agent that does not require cleaning with a solvent after the completion of soldering, and a bleed preventive method performed using the agent. [Structure] A water- and oil-repellent fluorine-containing polymer containing a perfluoroalkyl group, the main chain of which is CF 3 (CF 2 ) 5-10 , and the film to be formed has a critical surface tension of 22 dyne / cm or less. Is a hydrocarbon having 5 to 10 carbon atoms, an ether having 1 to 6 carbon atoms, a ketone having 1 to 6 carbon atoms and 1 to 6 carbon atoms Is dissolved in an organic solvent composed of one or more selected from the group consisting of [Effect] It eliminates the use of halogenated hydrocarbon solvents such as CFCs. |
