pH-Neutral vs. Alkaline Cleaning Agents: ZESTRON to Present Benchmark Study at the SMTAI 2010

Oct 18, 2010

Manassas, VA – October 18, 2010 – ZESTRON, the worldwide leading provider of high precision cleaning products and services for the electronics manufacturing industry, will present “Benchmark Study: pH-Neutral vs. Alkaline Cleaning Agents” during the SMTAI 2010 held at the Walt Disney World Swan and Dolphin Resort, Orlando, FL, October 24 – 28, 2010.

This collaborative study was prompted by recent industry trends and conducted to compare the cleaning effectiveness of pH-neutral and alkaline technologies at low operating concentrations as well as their effects on material compatibility.

During the past few years, significant changes in solder paste formulations and assembly processes have occurred. Post reflow residues of tin-lead and newer lead-free soldering materials are more difficult to remove due to increases in component density, larger component packages, higher lead counts, finer lead spacing and lower standoffs. While modern aqueous alkaline cleaning agents effectively remove these flux residues, achieving satisfactory results often requires an increase in temperature, exposure time, chemical concentration, and mechanical energy. This often presents a new set of challenges in the area of material compatibility.

With the emergence of pH-neutral defluxing technologies in early 2009, these formulations promised to set a new standard for material compatibility, while proving valuable to those who worked toward environmentally sound processes. As a result, potential users are very interested in assessing the differences between alkaline cleaning agents and the newer pH-neutral products, with regard to both, cleaning performance and material compatibility.
