Ususally, electronics solder comes with a built-in flux core. Among the solders I have laying around, I have a silver/tin solder with an "F-SW-21" flux core (ISO 9454-1: 3.1.1, this is zinc chlorid...

Feb 17, 2023 · The problem with those screw terminals as well as soldering directly to the PCB is that any movement or bending of the wires will quickly lead to fatigue failure.

May 17, 2015 · My manager at work told me that the liquid flux we use when reworking SMD circuit boards is electrically conductive, and that is why he INSISTS that we clean every board we work on. …

Aug 25, 2024 · I can't remove the solder from the pads. I want to remove the capacitor and remove all the solder but I can't get it to melt. I've tried going to maximum temp, 480C. I tried using flux and …

Jun 9, 2017 · This is not the stuff to use to solder electronic boards, this is for plumbing fittings, a flux to be used in addition to stick of solder. Electronic boards require either 'flux-cored solder' for hand use, …

Sep 5, 2011 · However, it is widely understood currently and historically that use of tin-lead solder in normal actual soldering applications has essentially no negative health impact. Handling of the lead …

Jun 23, 2024 · Consider using a larger soldering iron tip to improve heat transfer. Most soldering irons come with a "default" conical iron tip, which is not the best for transferring heat. A larger "knife" or …

Sep 20, 2017 · Unfortunately lead free solder makes really bad quality joints when manual soldering. It doesn't flow as well, wetting small pads can be difficult, often joints end up being weak and matte, …

Oct 28, 2009 · The transition to lead-free soldering has reduced strain on the environment, but for the operator, the hand soldering process has become more dangerous. The lead in the solder is gone, …

May 2, 2018 · There seems to be a lot of differing opinions out there on what is best practice. A lot of people seem to be shying away from the wet sponge due to the thermal stress it imposes on the tip. I …
