Heating bed thermistor broken?

[Desedi]

English as second language user here.

I got a Rostock Max V2, everything went well until I saw the temperature reading for heating bed. Nuzzle temp was around 28c but heating bed temp was 7c. Even when preheat, it defiantly feel like 40c but still LCD showing around 15c.
I thought the cause was my first time crappy soldering skill mess up something, since I remember there was a wire or metal strip coming out from the ONXY. I then remove the Kapton tape, and this happens.
The metal thing separated from the ONXY, and still showing 7c.

Is there a fix for this? Or do i need to but a new ONXY?
Thanks!

Looks like you over-temped the pad and it broke off. What temperature is your soldering iron at? It looks like its either way to hot or you're holding it on there for way too long. You can solve the problem by soldering the loose wire to the same pad as the thermistor lead that is now disconnected.

Thanks! Due to my soldering skill, I couldn't connect it. But solve it with lots of Kapton tape.
