Tabbing fluxes are commonly sprayed and dipped in automated processes, but flux pen application is best for hand soldering. Flux pens are small plastic containers with a spring loaded felt tip at one end. With a slight amount of pressure, the tip allows flux to wick through the felt and onto the cell.
- Since the tip valve closes between uses, evaporation is kept to a minimum.
- The unit is disposable; there are no needles or micro valves to keep clean.
- Application is uniform so there is less chance of flux inconsistencies.
I use flux pens for non-automated testing of fluxes.
