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.

What Causes Solder Balls During Hand Soldering?
To many operators believe the old myth that flux is your friend and you can never have to much flux. That is not true as to much flux will outgas at the end of the hand soldering process creating solder balls around the connection. This is one possible explanation as others have stated other causes as well.
