It is funny to read all these intricate methods for just soldering a package like (QFP, QFN, DFN, ...) when in the end the whole 2nd part of this discussion on the packages started between people defending the DIP and other blaming it. Yes, DIP is old but it still gets the job done for quite a few of us.
The neat thing about Microchip is they still offer this old packages which is easy to prototype with. Once, I was in contact with a Microchip support guy and he told me the DIP variants are being specifically offered, so students, hobbyists and others can play with their chips. They weren't selling high volumes of this package, however the DIP helped in the long run to sell more of the QFP, QFN, ... (much smaller than DIP) packages.
I guess he was right. I followed the same path with one of their chips. I put it on the prototype board and once the module I built around it worked as expected, I integrated with the rest of the modules. Afterwards, I switched to a small PCB and a QFN variant of the same chip. Indeed, the DIP package I played with helped the sale of its QFN variant.
