How AI can Accelerate R&D for Solder Paste Formulations
In this study, AI was used to predict the results of the key characteristics to better select the choice of formulas, to understand the relationship between molecules and to spend time on other aspects of the developments. To be able to exploit AI data in a relevant way, we highlight that the input database itself is crucial to generating reliable output data.
