the video is indeed vary good and has very important information. The way I usually solder SMT components is a mix of the techniques shown for the PLCC and the QFP. I actually use the residual solder that remains in the tip of the iron to allow the existing solder in the PCB and the components terminals to melt, and after some terminals are joined together I use a bit of solder to go ahead with the other terminals. I do not use some techniques shown in the video, like using a big amount of solder them removing the excess with this purpose, but in some previous industrial SMD soldering, the whole PCB with glued components were dipped into liquid, high temperature solder, so... what the heck do we know!
I agree with you, they are using new components and virgin boards, but the new boards seem to come with a coat of material in the soldering tags (terminals?) that I cannot identify. Maybe it has the same properties of the solder and helps soldering.
And yep, I was trying to mention the desoldering braid, or desoldering wick. Thanks.
I think the video gives enough guidance to a successful soldering. Can you find some old, not working PC board or daughter board, like slow modems or audio boards, that you could remove and re-solder SMD´s for the sake of 'skill enhancement'? Chances are that you´ll find your best, successful way of soldering. I'd bet that!
