What tools do I need to desolder a WB3S/CB3S/TYWE3S module safely?
You need a hot-air station (4–6 mm nozzle), flux, 0.6 mm leaded solder, stainless tweezers, and 99 % IPA for cleanup [Elektroda, p.kaczmarek2, post #20509125]
[Youtube] Desoldering WiFi module with hot air - WB3S/CB3S/TYWE3S/etc replacement method tutorial
TL;DR
- Shows how to desolder and replace a TYWE3S-footprint WiFi module, including WB3S, CB3S and similar modules on smart-device PCBs.
- Uses flux, extra leaded solder, hot air, and IPA PCB cleaner to lift the module cleanly and solder it back without pad damage.
- The same approach can turn ESP dev boards into WB3S/CB3S dev boards, and it also works for temporarily removing a module for programming or pad inspection.
- The demonstration ended with no ripped pads, but it requires a hot air station.

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.

The hot air method is more reliable, but it is also possible to use alternate way to remove module without tearing pads.

That’s a realtek chip. Is openbeken for realtek coming soon? [Read more]
Very nice spotting. There is indeed a new branch work in progress, but please note that this is a slightly different Realtek than the one we've been working on in the past. [Read more]
I have one note. Why is this video recorded in a foreign language for the voiceover? Nice theme with the hotel, more. [Read more]
@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... [Read more]
Oh please, I didn't even know there was an English-language electrode channel?! You need to promote it more! https://www.youtube.com/watch?v=VrF9eBJ7TUY [Read more]
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,... [Read more]
