So you can weld small SMD devices. The question is, how small is it?

Posted on August 9, 2021 by William

A highlight of Hackaday Remoticon last year was a welding competition. Teams from all over the world gathered online to complete the famous MakersBox SMD Challenge kit, in which a series of reduced-size LED circuits must be welded. The Hackaday staff performed very well. Although the 01005 resistor and LED did push the writer’s welding skills to the limit, it was still very satisfying to see it work. Lest that toolkit becomes too easy, [Arthur Benemann] Came up with something more evil; His uSMD is a 555 LED flash Use BGA 555 and selected 008004 widgets.

The trick to using 01005 is not to heat the solder joints for tinning and flux, but to heat the traces leading to it.If you can master components of this size, then 008004 may not be That Much smaller, so maybe the same technique applies to them. In his reminder email to us, he wrote “Welding 008004 is not much worse than 0201, you just need to zoom in“Although we think he might drag us a little bit, we can see that there is no reason why we shouldn’t. Sadly, he doesn’t seem to let us buy and try it out, so if you want to prove yourself with a soldering iron, you have to buy it yourself. PCB and parts. Nevertheless, we suspect that if you are the kind of person who can solder 008004, then this is hardly a difficult task for you.

At the same time, this is not the first welding challenge kit we bring you, of course, if you want to hone your skills You can find one of MakersBox on Tindie.
