Abstract

A solder flux that is useful in applications such as surface mounting of components on printed circuit boards has been found. After soldering, the residue from the flux is either removable by water cleaning or requires no cleaning at all. The achievement of these desirable properties is accomplished by employing a solder flux vehicle including a removing agent, a low vapor pressure component, a high temperature component, and a rheological properties promoter.
