Measuring coating adhesion to electronic boards using tape peel testing GPG117

A new test method (tape peel method) to evaluate conformal coating adhesion on electronic
assemblies has been developed. The approach directly measures the peel force needed to
remove a conformal coating. This is the only quantitative method to assess conformal coating
adhesion force. This document describes equipment, material, parameter and the procedure to
assess conformal coating adhesion.
