What is the best way to determine solder joint intermetallic composition? Metallography? XDS of the joint? Any input is appreciated.

Our first choice in determining the composition of metals would be to use Scanning Electron Microscopy (SEM) / Energy Dispersive Spectroscopy (EDS) analysis.

Dave's point is right on the money. This would be a destructive test..needing microsectioning.

Why do you want to do this analysis? There are limited IMC that can form.
