Yosker 10ml Flux Pen
by Yosker

The Yosker 10ml No-Clean Solder Flux Pen is a precision-engineered liquid flux dispensing instrument designed to achieve high-reliability solder joints during the assembly, touch-up, and localized rework of complex electronic components. Formulated explicitly to satisfy the rigorous performance constraints of high-density printed circuit boards (PCBs) within the sUAS, aerospace defense, and FPV drone markets, this high-activity tool strips away surface oxidation and dramatically lowers surface tension. Equipped with a specially designed, spring-loaded felt tip applicator, the pen provides a highly controlled, mess-free alternative to traditional flux bottles, preventing fluid pooling and ensuring flawless capillary wetting across both leaded (Sn/Pb) and modern lead-free alloy configurations.
