 For the effective removal of flux and associated contamination from printed circuit boards, Layton Technologies recently developed a precision cleaning and drying process. The technology is based on the application of the latest high solvency cleaning chemistries for removing residues from PCBs (polychlorinated biphenyls) produced using ‘no-clean’ and ‘no-lead fluxes’.Layton worked with DuPont and used its new generation defluxing solvent-Vertrel SFR-to provide a complete boardcleaning process. This will provide a more effective solution to manufacturers of high-value electronic components destined for critical applications where cleanliness standards and validation are paramount. In their north Staffordshire manufacturing base, Layton has an entire demonstration and testing facility. It offers complete cleaning trials and evaluation services for companies wishing to test the cleaning process on their products. They provide a range of cleaning technologies for electronics, semiconductor and precision components industries. These technologies include PCB cleaners and a range of solvents, flammable solvent cleaners, wet-benches, vapour driers and aqueous ultrasonic cleaning systems. |
