Can you explain a bit better, the top case keyboard doesn't have a daughter board as you can see here
Are you thinking of the trackpad?
@Sami Rahman - Thats the back of the trackpad
Here's the guide to replace the trackpad MacBook Air 13" Anfang 2020 Trackpad tauschen and if yours needs replacement here's the needed part MacBook Air 13" (A2179, Early 2020) Trackpad
Be careful here! the Early 2020 (Intel) is different from the M based Late 2020 model
The M series daughter board is glued to the uppercase using double sided tape which is quite tight. Using some Ethanol alcohol dripping a little around the boards edge should help is loosing it. You don't want to pry the board up with too much force as that will damage it. You appear to have found the board so it maybe easier to replace it.
War diese Antwort hilfreich?
I have finally done it during replacement of one liquid damaged top case. Beware of very strong black adhesive underneath and be extra careful while prying it to not bend it rendering it useless
Is there any tutorial about how to remove the keyboard connection board?
@eygjpefiy4yex2q - Its just glued down, but quite well! Using a solvent to help loosen the grip is all you need and patience lifting slowly.

Ah! You picked the wrong system! You are looking for the newer M series which is different! I've altered the model identifier so its set for the late 2020 not the early 2020.
