Safe-T-Flow demo, part deux

Arduino Technology

In this video, Limor of Adafruit Industries shows how she laser-cuts masks for PCBs for easier application of solder paste (think: silk-screen inking) and then uses her reflow robo-skillet, controlled by her new Safe-T-Flow controller, to solder an SMT chip onto one of her Boarduino clone kits.

    Any tips on doing lead-free reflow soldering? I think the only difference is the reflow temperature, 235°C instead of 220°C, but I’d like to know if someone actually did it successfully.

    Also, Teflon is known to emit noxious fumes at or above 260°C, so be careful (look up “teflon flu”). It’s extremely hard to find cooking instruments not coated with teflon these days. An oven might be a safer choice.

    @vivi: good point. it kills birds too if I recall. you can probably sand off the teflon, as circuit boards are non-stick.

    It’s worth pointing out that the reflow fumes themselves aren’t a good thing either…

    It’s SOLDER woman not SODER, SOLDER Dyou hear?

      @Queens Inglish

      Sounded right to me. I’ve never heard anyone ever pronounce the “L” when they talk about soldering.

      1. Michael C says:

        “Soder” seems to be a North American thing. In Australia we pronounce the “L” and I know some English people who do too. I know of at least one Canadian who does not pronounce the “L”. It seems like a strangely inconsistent pronunciation decision, given that no-one skips the “L” in “soldier”.
