Coatings and methods, especially for circuit boards

摘要

A coating composition for use in protecting metal, and for use as a soldering flux, and methods involving the same, especially for circuit boards. One coating material can serve as a metal corrosion inhibitor, a no-clean soldering flux, and/or a protective coating in replacement of a conformal coating. In its most preferred form, this invention serves all three functions in the manufacture of an electrical circuit board.;The principal ingredient of the coating is an N - fatty acyl derivative of an amino acid.
