AI to Predict Compatibility Between Solder Paste Residues and Coatings
This paper shows how AI is used to predict compatibility results between solder paste residues and coatings. A physical compatibility study is carried out to benchmark some combinations of solder pastes and coatings of the market. Results between AI prediction and the physical tests are compared to choose the right AI model for a good prediction of the compatibilities.
