Interflux PacIFic 2009MLF has been developed to minimize micro solder ball formation. It is an adapted version of the interflux PacIFic 2009M. Conventional VOC-free fluxes may give more solder balling than alcohol based fluxes on micro ball sensitive solder masks.interflux PacIFic 2009MLF minimises micro solder balling on these solder masks. Interflux PacIFic 2009MLF is absolutely halogen free. The flux allows a change over from alcohol based fluxes to water based fluxes with absolutely no disadvantages. Interflux PacIFic 2009MLF is perfectly suitable for lead-free soldering and is typically applied by sprayfluxing.
