ASMR Satisfying Chip Capacitor Solder Reflow
Nice close-up!
Though, it looks like the solder didn't wet to the PCB pads very well, is it? I was expecting the solder to wet the PCB pads, and to flow more on the PCB pads, too, so to to produce a concave solder joint surface. Here, the final solder surface is convex, in the shape of a half small bubble (on the capacitor's pad).
I'm not experienced enough in SMD reflow, isn't it too little solder paste there?
I agree with your observations. I cannot speak for the video or the setup that was used. I think the video is intended for demonstration purposes. I think they used a test jig for this, but I don't know.
It looks like the capacitor is 0402 (imperial) or maybe smaller? It might explain the visible solder balls in the paste. It would be interesting to know the soldering standards for Class 1, 2 and 3, etc.

I don't have photos, kinda obviously, but just something neat. On my walk tonight, saw a train of rather fast moving dots in the sky. Looked like a blur at a distance, but was obviously a train of dots once overhead. Which must've been a new launch of satellites. Probably Starlink then?
And indeed, there was a Group 4-14 launch earlier today, so there you have it.
The sighting was approx. 8:40-8:50 pm CDT, which gives you a pretty good idea where I was at.

I'm confused. One minute they say that nobody really went to the moon, then the next minute they say there are moon bases all over the other side.

These are aliens bases. They were built by aliens. And people from the earth did not fly
