Abstract
Disclosed is a method for making a solder joint without flux, in the presence of an inert gas. A pair of articles having solder-coated surfaces are heated to melt the solder, pressure is applied to the joint region, and the articles are cooled. During the heating step, inert gas is flowed over the articles.
