Abstract

A test for determining the ionic contaminants on printed-wiring assemblies was proposed, defined, and found feasible. The basis of the test is the change in electrical resistivity of the solvent with which the chemist washed the printed-wiring assembly. The solvent was 75% by volume, ACS Reagant Grade isopropyl alcohol. The resistivity is lowered when contaminants, such as flux residues, are dissolved. Establishing acceptance criteria for clean printed-wiring assemblies was beyond he scope of this investigation. (Author)<br />Revision of report dated 25 May 72.
