Method for use of preflux, printed wiring board, and method for production thereof

摘要

A method for the production of a printed wiring board according to this invention includes applying a preflux represented by the following general formula (1): (1) (wherein R1 stands of H or an alkyl group of one to 17 carbon atoms, R2 for H or an alkyl group of one to six carbon atoms, and n for an integer in the range between 0 and 3) or the following general formula (2): (2) (wherein R3 stands for H or an alkyl group of one to six carbon atoms, R4 for H or an alkyl group of one to six carbon atoms, R5 for an alkyl group of zero to seven carbon atoms, and n for an integer in the range between 0 and 3) to a printed wiring board on which circuits have been formed and then performing an oxidizing treatment on the printed wiring board.
