Cleaning with pH Neutral Chemistry - Background, Applications, and Benefits

May 23rd, 1:30 PM EDT

The greater use of lead-free solder paste and the required higher reflow profiles have resulted in more difficult to remove burnt-in flux residues. Coupled with increases in component density, larger component packages, higher lead counts, finer lead spacing, and lower standoff distances, effective cleaning is greatly challenged. Newly developed pH neutral formulations have proven to be capable not only of removing these difficult post-reflow residues from complex board geometries, but do so without affecting material compatibility of sensitive components. Additionally, they perform at low concentration levels. This ZESTRON Academy webinar provides an overview of pH neutral cleaning agent development as well as reviews the performance of pH neutral cleaning agents demonstrating their effectiveness with regard to material compatibility and cleaning performance.
