I don’t know from hot air soldering, so I can’t judge the details of this homemade rig, but it’s certainly a thorough Instructable. Hot air work/SMD soldering is something I need to break down and learn. Maybe you too? SparkFun has a decent tutorial .

    All hail the overheated chip ?

    Thats what I thought. I’ve overheated several QFN chips with my digital adjustable hot air station. This would be like soldering with a blow torch.

    I just dont get it. A hot air station is a great tool. Its not very pricey, great 3-in-1 stations can be had for around $100 and hot-air-only for less than $60 (x-mas and birthday territory for the poor kids among us…). It makes a great first purchase after you’ve made a few boards and decide to continue. At $100, my Auyoe is my the most expensive electronics TOOL, but half as $$$$ as my cheapest (purchased) microcontroller programmer or DEV-board!

    With something that does such delicate work, in the 200-600 degree C range, why not just get the real deal and save the hacking for the electronics? I do everything myself, but I cant justify a DIY hot air station to save $60 (not including your parts cost).

    Cost…. $10 Australian $$$ …. My wallet …. empty …. cost for these units in Australia … don’t go there. Adjusting the amount of hot air and it’s temperature by using a power voltage regulator and numerous nozzle tips has worked for me…fried chips? None that I know about. Say’s a lot about the shop brought version mentioned here…lol. If I can desolder parts by the way I describe and not cook my finger (especially when desoldering mosfets), I must have done something right here

    Perhaps the knockers who reckon this a blow torch should check this guy out…
