Braid works the other way - it keeps drawing as long as you hold it there, and it gets into places a nozzle cannot reach.\u003c\/p\u003e\n\u003cp\u003eFlat copper braid loaded with flux, 2.5 mm wide, 1.5 m on the spool.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eCopper wicks molten solder by capillary action - the same reason a paper towel pulls up water. The flux is what makes it happen: it strips the oxide off both the braid and the joint so the solder actually wets the copper instead of sitting on it as a bead.\u003c\/p\u003e\n\u003cp\u003eLay the braid on the joint, put the iron on top of the braid, and wait. You are heating the joint through the braid. The moment the solder melts it climbs into the copper and the braid darkens. Lift both together. If you lift the iron first, the solder freezes and now the braid is soldered to the board.\u003c\/p\u003e\n\u003cp\u003eCut off the used length. Loaded braid does not wick.\u003c\/p\u003e\n\u003ch3\u003eWhere it stops\u003c\/h3\u003e\n\u003cp\u003eBraid takes heat. It is a heatsink sitting on the pad, so the iron has to be hot enough and big enough to get through it. On a fine pad with a small tip you can end up holding heat on a pad for several seconds, and pads lift. Wider braid is worse for this, which is why 2.5 mm rather than 4.\u003c\/p\u003e\n\u003cp\u003eIt will not clear a plated through-hole completely. It takes the surface solder; getting a lead free in a through-hole usually needs heat and a pull, or a sucker.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCalifornia Proposition 65 warning:\u003c\/strong\u003e this product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.
