the molecular weight assessment of residues for over two dozen channels. This capability is critical to our failure analysis work at Foresite, as it allows for identification of specific organic acids and flux activators

. Martin Wickham of NPL will present research on coating systems for organic PCBs that are designed to operate at 250°C. The research finds that there is a reduction in oxidation rates to exposed metals in both the inner and outer layers within multilayer structures

with metal oxide [19,20]. Organic flux residues trapped within solder can outgas and create voids [21], and this is minimized when using a fluxless process with formic acid. For this study, formic acid concentration was a key variable that was explored

. We are using a lead-free organic rosin core solder and apply additional liquid rosin flux when soldering fine pitch components. We are running the soldering irons between 750 and 800 F
