[Analysis Case] Component Analysis of Flux in Cream Solder

Comprehensively qualitatively analyzes the rosin, thixotropic agents, surfactants, and other components in cream solder.

Cream solder (solder paste) is a paste-like solder made by mixing metal powder with flux, such as rosin, and is used when mounting electronic components on a substrate. The solder flux contains various organic components ranging from low molecular to medium and high molecular weight, including solvents, activators, rosin, and thixotropic agents. Here, we present examples of a wide-ranging qualitative analysis of these components using GC/MS and LC/MS.
