Indium Sn96.5 Ag3.5 Flux CW807 1.8-2.5% 0.020" (0.5mm) - " Reel

CW-807 is Indium Corporation’s best-selling flux-cored wire, primarily because it is compatible with all Indium Corporationno-clean solder pastes, wave fluxes, and all common soft solder alloys. It also solders very well while still meeting the mostrecent requirements of J-STD-004B type ROL0. CW-807 contains less than 500ppm total halogen, so it can be consideredhalogen-free by both J-STD-004B and JEITA ET-7304. CW-807 passes the more stringent Surface Insulation Resistance (SIR)and Electromigration (ECM) requirements of J-STD-004 revision B; therefore, the no-clean residue will be electronically safefor virtually all applications. Also when properly configured, cored wire with CW-807 yields superior results in automatedsoldering operations, including laser soldering.• Halogen-free per J-STD-004BTo be halogen-free per J-STD-004B, the formula mustcontain less than 500ppm of any kind of halogen, ionicor nonionically bonded chlorine, bromine, or fluorine.This is new to J-STD-004B since fluxes that conformto the original J-STD-004 or J-STD-004A may stillcontain halogens that only disassociate at solderingtemperatures, but leave a residue that contains ionichalogen.• Light-colored, low-smoking, rosin-containing fluxRosin, modified rosins, and resins contribute toenhanced heat stability and reliability; however, insome cases, rosins and resins may interfere withprobe-testability.• Tested compatibility with Hot Air Solder Leveled(HASL), Immersion Silver, Electroless NickelImmersion Gold (ENIG), and Organically SolderPreserved (OSP) Copper surfaces.• Tested for use with all common lead-free, low- orno-silver lead-free, tin-lead alloys, and many others.In the core, CW-807 has a clear, colorless appearance. Uponsoldering, CW-807 smokes very little and has a mild, sweetodor. CW-807 contains no added volatile solvents or waterabsorbent materials to limit spattering. The flux residue isclear and slightly shiny. It typically blends in well with epoxyglass circuit boards and does not detract from the board’sappearance.
