Thread: lead-free vs leaded solder?

  1. #1

    Default lead-free vs leaded solder?

    Ahoy from Seattle!

    Any preferences between leaded (60/40) vs. lead-free solder?
    I hear leaded solder works better, but haven't looked into it.

    Parents ask that I don't use leaded solder around my students, so I don't, but for my own projects, I was wondering if there's a discernible advantage.

    It's all preference really, I use lead free in my engineering classes bc they supply it, but I use leaded at home. I feel like I get better heat transfer and solder flow resulting in nice joints from the leaded flow so thats my go to. But realistically either would be fine

    As mentioned, leaded flows much better and is much easier to work with. If the fumes make you nervous you can get an extractor fan or get creative and make one from a cheap computer case fan and charcoal filter.

    Thanks, Light Bringer! I appreciate your advice!
    And please look for a new post from me - soon, I hope - with student questions on wiring strategy ... your input would be invaluable.

    Thanks, Darth Chasm! Excellent point - the extractor fan is a must.
    And as I mentioned in my post to Light Bringer, please look for a new post from me - soon, I hope - with student questions on wiring strategy ... your input would be invaluable.

    You値l find that tin/lead with a little silver will likely work the best. It痴 what the pros use. 😉🤫

    One problem with tin based solder is whiskers. Over time the solder joints may grow whiskers that can cause shorts if they impinge on a nearby joint. My company has spent years working on processes to reduce the risk in our manufacturing process as we make DAL A aerospace products and have RoHS obligations to meet. For a lightsaber build, the solder joints made by hobby soldering is probably far enough apart to negate the risk, but for very dense SMT boards, this can be a problem.
