Resin Test Exposes Residues to the Naked Eye
February 7, 2007 |Estimated reading time: Less than a minute
MANASSAS, Va. ZESTRON America introduced the Resin Test, an analytical service that exposes residues on assemblies prior to conformal coating. Contaminant distribution can be quantified under a microscope.
When the test is applied to a board, present residues react, discoloring from yellow to brown, depending on contamination. This effect is visible to the naked eye; however, under a microscope, discolored areas appear as a thin film, allowing users to determine level of contamination and areas affected. The portable test enables on-site analysis during production.
