Certain components or package configurations were observed to exhibit more entrainment and/or entrapment of cleaning residues.   This paper will discuss the “physics” of liquid entrainment / entrapment and their effects on component materials with experiments performed to determine the minimum amount of component vent area required to adequately rinse components of their cleaning residues resulting in a “Design for Rinse-ability” specifications or guidelines to deploy.  In addition, accelerated humidity testing with electrical testing will be discussed, that was performed to determine the degree of degradation / corrosion or electrical reliability of components exposed to controlled or known amounts of cleaning solutions entrained.
