Among the three kinds of experimental fluxes the water soluble YH-61 flux is the best flux for Ni-P alloy film, but rosin fluxes of nonactive and modified by bromo-salicylic acid are not suitable for soldering of Ni-P alloy film.

• 在试验的三种助焊剂中；普通松香和溴化水杨酸改性松香焊剂(SD)不适于Ni-P层的焊接；只有YH-61水溶性焊剂才适于化学镀Ni-P层的焊接.
