Residues remaining on surfaces can adversely affect the functional reliability of electronic assemblies, which in turn, can be very costly for the manufacturer and the end user.  To evaluate cleanliness, ZESTRON offers Basic and Advanced Analytics.

Surface Analysis
Adequate cleanliness level assessments of your electronic assemblies can be performed using methods such as the ZESTRON® Flux and Resin Test, surface tension analysis, Ionic Contamination measurements and Ion Chromatography.

Climatic Reliability / Long-term analysis
Assembly surface analysis prior to conformal coating or wire bonding can be performed using contact angle measurement methods as well as the ZESTRON® Ink Test.  For failure analysis assessments of electronic assemblies, methods such as the Water Stress Test and copper related surface deficiencies are readily available.
