How much wattage do you need? How does this relate to temperature? Just how hot are the cheap RadioShack irons?

  • At 1:20 how could solder melt if the temperatire is below 500°F?

  • 63/37 melts at 361 F, see our howtosolder guide for an explanation of why iron temps are so much hotter than that. CuriousInventor / HowToSolder

  • are the 15 watt irons betr for smt

    or is a tempture regulator station beter??

  • because many smt parts draw little heat, you can get away with a 15 watt iron in many cases. But in general, a regulated iron will be better since it will be able to compensate if you are soldering many pins in quick succession. Also if you need to solder a heat sink connected to a ground plane, the extra wattage and regulation will be helpful.

  • Well done. Informative and a very clean presentation of information.

    Everyone who wants to make an information or how-to video needs to watch this one.

  • Awesome, professional, and informative video. Thank you for taking the time to share. I've learned what I wanted to know about temp vs. wattage of soldering irons, and how it applies to various soldering work. I have no more questions regarding this issue after watching. Thanks so much!

  • Solder is pronounced SOL-DER not SOD-ER..... Don't forget the 'L' as it could lead to misinterpretation! Hi Hi!!

  • I meant it gets to the point without rambling.

  • Good video, gives me what i want.

  • Great video.

  • Thank you!

  • Thank you so much!!! This was exactly what I was looking for and was very informative.

  • It's that shitty RoHS lead free crap foisted upon the world. I didn't know there was an epidemic of lead poisoning caused by solid solders in the landfills enough to legislate the good stuff (60/40) out of existence. I've screwed a number of good boards cause of the shit that has a 1,000,000 degree melting point.

  • @Shockszzbyyous google it

  • Great vid. It answers the Great Temperature-Wattage Question. Thanks!

  • uh what is 1F in c' degrees (Celsius) ???
