• Conforms to J-STD-004B Flux Type ORM1

WF-1098 is an alcohol-based, halogen-containing, water-wash wave soldering flux developed to comply with the latest J-STD-004, version B, for soldering through-hole, bottom-side surface mount, and mixed-technology circuit boards. It performs well with both Pb-free and SnPb soldering processes and is compatible in both wave soldering and selective soldering applications. WF-1098 contains halogens which give the flux additional activity and heat stability. The residue left by WF-1098 is highly water-soluble, allowing easy post-soldering removal in both batch and in-line cleaning processes.
