Rosin flux removers are an important tool for the general sub-set of electronics and PCB cleaning. Rosin fluxes come in grades of activation, from plain rosin fluxes, rosin activated fluxes, rosin mildly activated fluxes, and synthetic or SA fluxes. These traditional RMA, RA and SA fluxes are seeing a resurgence in the marketplace as no-clean fluxes have not proven to be the economic panacea they were originally proclaimed. Traditional rosin-based formulas are higher in organics but lower in salts, resulting in strong, bright solder joints. They actually are easier to clean than no clean flux and paste formulations, and white residues rarely are a problem. These materials deliver PCBs with exceptional performance and proven longevity.
MicroCare offers a variety of formulations for the cleaning R, RA, RMA and SA fluxes.
Special feature: MicroCare Case Study #15 deals with the cleaning problems associated with mixed flux and solder paste residues, which can result in white residues.
