CX18 is a no clean flux core wire solder designed to offer excellent soldering results with all alloys and on all surface finishes. Engineered for high operator satisfaction CX18 is a low odor/smoke formula which promotes thermal transfer, and fast wetting without the need for additional flux. CX18 post solder residues are minimal, clear and pass IPC-004A and IPC-004B SIR and corrosion requirements. With excellent wetting characteristics, it is compatible with all flux types.
