New-Generation, Low-Temperature Lead-Free Solder
In this paper, the roles of additive and bismuth content will be discussed. Eutectic SnBi and three newly designed SnBi-based alloys were experimented upon.
Technical Paper
Vapor Phase and Backward Compatibility
We use lead-free solder paste with a melting point of 217 degrees C, along with 230 degree C Galden. We have a new project that uses tin-lead solder. The Assembly Brothers, Phil Zarrow and Jim Hall, offer their suggestions.

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.
