You want joints that look like you actually know what you're doing – bright, smooth, shiny. Not the dull, pitted mess that happens when your flux isn't up to the job. This 10g resin-based gel is mildly activated and built for a wide range of soldering work. The wetting ability is noticeably better than what you'd get from a generic tin, so the molten solder spreads clean across the pad. Residue stays very low and crystal clear, even at the higher temperatures lead-free alloys demand. It also cuts down on voiding and handles high humidity well. Supplied in a syringe for controlled application. Works with lead-free solders. Chemistry is developed for air reflow
