63-OAJ – 63/37 Water Soluble

63-OAJ – 63/37 Water Soluble

63/37 OAJ Flux Cored Leaded Solder Wire has been formulated with an innovative amine neutralized halide- activator system. This novel system offers a high activation level that provides rapid oxide removal and maximum capillary action, resulting in faster wetting on all surface finishes and plating. OAJ flux residues MUST be removed after soldering. IPC flux classification – ORH1.
Post-process residues can remain in place up to 8 hours*. Flux residue can be removed with normal tap water @ 38°C – 60°C (100°F – 140°F) with a DI water final rinse. Use of a pressurised spray cleaning system is suggested, but is not required.
