Why ‘No-Clean’ Flux Still Requires Cleaning in Modern Electronics
Dr. Adam Klett, Director of Science for KYZEN Corporation, explains why “no-clean” flux in electronics often still needs cleaning. This flux was created in the late ’80s to avoid cleaning after certain solvents were banned. It worked well for older, larger electronics. However, modern devices are much smaller and more tightly packed, which can trap residues and contaminants. This increases the risk of electrical problems and failures, especially in critical equipment. Dr. Adam points out that while “no-clean” flux reduces cleaning needs, many modern electronics still require cleaning for optimal performance. The good news is that new cleaning solutions have been developed to handle these advanced, compact designs effectively.
