Design for cleaning is a laudable goal; it is often unachievable. Nearly all high-value electronics assemblies require post-reflow cleaning to remove flux and the residue of an assortment of thin film and particulate manufacturing residue. We will explain why “no-clean flux” must be removed and how soil and soil residue differ. Topics include increased assembly complexity, miniaturization, increased product performance requirements, and the impact of safety/environmental regulations.
To meet upcoming challenges, electronics assemblers must get strategic about cleaning. We will outline the range of cleaning choices and explain the inherent physical and chemical limitations of water. We will explain the importance of the collaboration between components suppliers and final assemblers. Cleaning techniques that expand the horizons of soil removal include high frequency ultrasonics, cyclic cavitation (cyclic nucleation), and non-chemical cleaning options such as CO2, steam, and laser cleaning. We will discuss the potential and limitations of newer techniques as well as testing requirements.
