As a follow-up to the article “Jet Printed Solder Paste an Cleaning Challenges”, this study tests a conventional no-clean flux chemistry with increasingly finer SAC305 solder powders using a variety of cleaning chemicals and methods to try to quantify the impact of finer mesh powder on flux removal.
In this white paper, you will learn what impact the finer solder powder paste deposits have on the cleaning process and materials using surface insulation resistance measure (SIR) and ion chromatography analyses.
