Science Channel Is Fake?

Today there was an image of a Bloke using a soldering pencil on a surface mount board. The tip of the soldering pencil was on one leg of an IC.

Sad, no one responding seems to know fake from real. No answer award given.

    If you don't understand something, that means that you don't understand it. Not that it's "fake".

    What's fake about that? I routinely use a soldering iron on surface mount parts. 0.5mm pitch ICs is quite doable with the right tip & technique. When shooting videos like this, it is often a staged scene (i.e. not real work) to make the shoot clearer or the company doesn't want to show what's in their product. Think of this a stock video footage.

    On the ridiculous side, I use a toaster oven to solder surface mount parts when the pads aren't accessible to a soldering iron tip.

    I don't see the problem?

    It's not unusual to use a soldering iron to reflow a joint that does not look too good, or remove excess solder after repairing or reworking a board, including on surface mount.

    Example - see the photo below.

    We had to fit the larger IC near the centre of the photo by hand in a batch of PCBs, as the surface mount assembly company did not have stock when we needed the boards.

    They were initially soldered with a hot air tool, then any bridges or joints that did not look to have flowed properly fixed with a temperature controlled iron.
