WS715M WATER SOLUBLE LIQUID FLUX FEATURES HANDLING & STORAGE Excellent Wetting Parameter Time Temperature Lead-Free and Tin-Lead Compatible Sealed Shelf Life 1 year Room Temperature Easy to Clean with DI Water WS715M has a sealed shelf life of one (1) year when stored at Low Foaming in Wash room temperature. Do not store near fire or flame. Keep away pH-Neutral from sunlight as it may degrade product. WS715M is shipped ready-to-use, no mixing necessary. Do not mix used and unused DESCRIPTION chemicals in the same container. Reseal any opened containers. WS715M is an alcohol based, organically activated, rosin-free, Storage conditions range from 4-40C (40-100F). water soluble liquid flux designed for wave and selective solder APPLICATION applications. WS715M may be applied by spray, foam, dip or WS715M is formulated for application via spray, foam, brush, brushed. WS715M is a buffered pH-neutral flux with a highly or dip. WS715M is ready to use directly from its container, no durable activator providing excellent wetting characteristics thinning required. When spray fluxing, proper flux coverage producing bright, shiny solder joints even on difficult to wet and uniformity are imperative. A dry flux coating of 500-1500 materials. WS715M performs well on all surface finishes including micrograms per square inch is typical. ENIG, OSP and HASL. WS715M residues must be removed after PROCESS GUIDELINES soldering. Using thermocouples attached to the top of the PCB, the topside assembly temperature should be between 85-110C (185- CHARACTERISTICS 230F). It is important that the flux be dry prior to entering the wave regardless of temperature or spattering will occur. Smoking may occur and is considered normal if it is not Wetting excessive. Recommended contact time with the wave is Characteristics dependent on wave configuration, pot temperature, alloy type and thermal mass of the assembly with 3-8 seconds being SIR Reliability typical.
