Do I really need a microscope to solder SMD parts?

June 1, 2017 | 08:00
Where SMD parts are involved in assembling new boards or to repair damaged boards, the drag soldering method is now common place. With a little practice, this rather unrefined soldering technique actually gives brilliant results, especially with terrifying quad flat packages. This video shows how to drag solder SMD parts with a high density VQFP 64 pin package, where V stands for very thin or very fine pitch! Sure, a microscope can help (especially when you’re done soldering and checking for bridges), but as the demo clearly shows the magic word is flux.
There is a certain level of skill involved, if you have never tried it before don’t expect results this good. In reply to the viewer’s question: Do I need anything more than a flux pen and a soldering iron? The answer is no, just some practice… and courage
