Flux for soldering electronic components on circuit substrates, and mounted or unmounted circuit substrate |
摘要 |
The invention provides a soldering flux for mounting circuit substrates, which is free from any organic solvent attributable to air pollution and dispenses with any washing step. The soldering flux is obtained by dissolving a rosin modified by an unsaturated organic acid according to the Diels-Alder reaction in an aqueous solvent. A volatile basic agent may further be contained in the flux.
