Method and apparatus to evaluate effectiveness of cleaning systems for high density electronics

摘要

An apparatus and method for a cleaning process control is disclosed. The apparatus includes two parallel plates of glass that have a plurality of shims positioned therebetween and a means for clamping these plates of glass firmly against the shims. A contaminant is positioned between the plates of glass and the apparatus is cleaned using a selected cleaning process. The apparatus can then be inspected to determine the effectiveness of a particular cleaning process by peering through the transparent glass plates to inspect for any remaining contaminant. The apparatus can then be cleaned more extensively and used again to check a different cleaning process.
