Hi there, I'm using a semi-professional desoldering iron from Ersa (https://www.kurtzersa.de/electronics-production-equipment/loetwerkzeuge-zubehoer/loetstationen-entloetstationen/produkt-details/digital-2000-a-5.html), The 3rd picture is pretty close to my setup. It can be seen in action here on a SB Classic: 'https://youtu.be/XDod-obw6Iw ' (https://youtu.be/XDod-obw6Iw) The video illustrates how the entire solder around the pin becomes liquid on both sides of the pad before getting extracted by vacuum. Some pins always remain stuck and require a second pass but overall this makes it really easy to non-destructively remove almost any component with low risk of damaging the board or the extracted part. If you are wondering why the vacuum pump starts running *after* the solder was sucked away, that is because vacuum is immediately available and when I trigger it, it does not need to build up first because the entire system is under low pressure already. When the upper threshold of the pressure level is reached (i.e. vacuum gets too low), the pump restores it automatically. It's pretty noisy though so I cannot do any desoldering at night without disturbing the neighbors. PN me if your Boom / Classic / Transporter display has issues!
