![]() Evaluation of the bi-material strip bending test method appears not to be effective in the conformal coating selection. Different simplified approaches are compared to help identify desired mechanical profiles for coatings to be used in a harsh environment, focusing on silicone characterized by low rigidity and high deformability compared to alternative chemistries. Coating exposure to thermal shock or temperature cycles may initiate cracks, a common failure mechanism of conformal coatings. The stability of print circuit board (PCB) conformal coating is critical to guarantee the long-term performance of electronic components on PCB boards.
