The 836-P No Clean Flux Pen contains a homogenous mixture of halogen-free, low-solids organic flux. It exhibits excellent wetting and fluxing activities, and it leaves essentially no residue on the assembly after soldering. The 836-P No Clean Flux Pen may be used for both leaded and lead-free applications. A chiseled tip provides exact delivery of the flux to the surface. The 836-P pen is designed to dispense flux precisely. It is excellent for prototyping and rework/repair of printed circuit boards. It works well on switches, sockets, heat sinks, chip carriers, and surface mounted device pads.
