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?

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

        “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”.
