AI Thread Summary
The discussion centers around the challenges of hand soldering small surface-mount devices (SMDs), particularly in the context of a challenge known as "SMD challenge misery edition." The focus is on the difficulties of soldering components like ICs, LEDs, and resistors, with an emphasis on the fragility of the smallest elements when using hot air tools. The conversation also touches on the existence of 01005 components, which are typically used in machine production, highlighting a shift in the discussion from 0603 to 1206 sizes. The participants express a mix of surprise and curiosity regarding the various SMD sizes and their implications for hand soldering.

@berkeman - remember the guy who asked about replacing 0603? Quite accidentally I just found something called "SMD challenge misery edition" (there are several versions, TBH I have no idea which one was first so I just grabbed the best picture I could find).

Yes, the idea is to hand solder the IC (which seems to be the simplest part), LEDs and resistors. Hot air will easily blow the smallest elements away.

Actually up to now I even didn't know 01005 exist :oops: (and yes, I know they are for machine production).

This one is shifted up and starts at 1206.
