A method of brazing which includes deposition of brazing material by electrophoresis. Deposition is performed with a low viscosity, low surface tension bath comprising an alcohol, a nitroalkane, and a complex ionic solute. Brazing powder is added to this bath in the quantity of about 0.02 to about 0.04 kilograms per liter. A nonconductive coating is applied to areas where a brazing material should not be deposited, such as small passageways. This method is shown to be useful in applying brazing material adjacent small passageways, such that the brazing material is accurately deposited and does not flow into and interfere with the passageway after the braze joint is formed.
