186 Flux Pen®, Copper Material

Kester Flux-Pen® is a unique tool for rework and touch-up soldering. It allows controlled application of flux, eliminating the mess from flux bottles. The chisel point allows for work in very confined spaces. The flux pen is ideally suited for tab assembly no-clean and surface mount rework application because it can deliver flux to a specific area.
Kester 186 Flux Pen® is specifically designed for leaded and lead-free rework of conventional and surface mount circuit board assemblies. Kester 186 under MIL-F-14256, was QPL approved as Type RMA. Although the fluxing ability approaches that of Type RA flux, residues after soldering are non-corrosive and non-conductive. Kester 186 has been developed for use in critical applications where difficult assemblies are to be soldered, but process requirements stipulate use of Type RMA flux. Kester 186 possess high thermal stability for soldering multi-layer assemblies which require higher temperatures.
