What does wetted mean? Why are "one sided pad not fully covered" and "too little solder" bad things? The image on the left at 1:45, why is it wrong? The joints that have seen too much heat, is that a major issue? Is it fixable? Thank you.
Wetted means no sufficient flux has been added to make the solder flow nicely. One sided or too little: sooner or later when being used in challenging environments (with vibrations for example) these will break because of the bad physical connection. Image on the left: this has a dull look, it can mean that you have a cold solder joint where solder is above the pin and pad as a "cap" rather than being actually connected to the pin and the pad. Too much heat: the biggest risk that you have there, is that your tracks might start to separate from your PCB. That's bad 🙂 Hope this helps!
Finally I understand the topic, thanks
