Key Considerations When Selecting an Aqueous Cleaning Agent

June 3, 2026 | Adam Klett, Ph.D, KYZEN Corporation

Selecting the appropriate aqueous cleaning agent is one of the most consequential decisions in mitigating contamination risks in high-density designs. Highly dense electronic assemblies have introduced a new level of sensitivity to contamination. Reduced conductor spacing, bottom-terminated components, and elevated power densities significantly increase the risk that even minimal flux residues will lead to electrochemical migration, leakage currents, and long-term reliability failures.

Nolan’s Notes: Cleaning With Smaller Geometries

June 3, 2026 | Nolan Johnson, Nolan's Notes

Cleaning is an under-appreciated, possibly under-considered step in the PCB assembly process. Smaller geometries, combined with increasingly larger bottom-terminated packages for complex components, using ever-smaller pitch sizes, mean that cleaning solutions must drive deeper and rinse out more easily than ever before, and must extract all flux residue and other contaminants.
