Abstract

A conformal coating control method includes arranging at least one conformal control surface feature on a surface of a printed circuit board proximate perimeter pads of an integrated circuit. The method also includes soldering, to the printed circuit board, the integrated circuit. The method also includes applying a conformal coating material to the printed circuit board, wherein the conformal coating material is at least partially restricted from flowing between the integrated circuit and the printed circuit board by solder flux residue accumulated proximate the conformal control surface feature.
