Here's a quick guide showing how to desolder a WiFi module with TYWE3S footprint from a smart device. The guide covers usage of flux, extra leaded solder and IPA PCB cleaner for a reliable WiFi module replacement process. Soldering the WiFi module back in it's place is also shown in the video. Our tutorial can be very useful for anyone willing to swap one WiFi module with another, or just needing to desolder module temporarily to program it or to check the pad markings on the bottom silk screen. No pads were ripped in making of this guide.
Futhermore, the same approach can be of course used for any other, non-IoT device. You can desolder ICs the same way, but here we'll focus on IoT application of the method.
The same method can be used to create a WB3S/CB3S dev boards from ESP dev boards - just replace the module.
Of course, for the shown method the hot air station is required.
If you want to see a tricky method for desoldering such module without hot air, please see here:

@pepedombo the video is on the English-language channel Elektroda and is aimed primarily at users from abroad (although viewers and subscribers from our country are also 100% welcome!), who have been active on our international website Elektroda.com for some time now , here: https://www.elektroda.com/ It is thanks to their activity that our list of interiors of devices with WiFi (and not only ...) slowly reaches 300 entries (at the moment there are 295): https://openbekeniot.github.io/webapp/devicesList.html The topic itself was originally uploaded to the English website, as evidenced by this bar above its title:
Of course, the Polish version would also be very useful, I'll talk to the assistant and maybe she'll record it, we'll see, but the fact is that if the video is in English, some of our compatriots will watch it, and if the video is in Polish (and only English subtitles) ), so no one from abroad will be interested...
The subject of hotair can be rocked to the limit, because it seems simple and it seems to work, but in practice you have to burn a few records to understand the basics and then with something we care about, a question mark will always light up. In terms of viewership, it seems ok, such a hot why not, but it would have to be some powerful series that treats everything. For example, xbox discs are such heat sinks that I regret learning on them
