Hi Everyone.
I have an iphone 7 in repair. someone already change the screen.
I try also with an original screen, but problem is same.
Touch ID, doesn’t work, and when i simply touch home button, its vibrate continuously and very hot.
I have Schematic and ZXW.
Can i direct putout u10 ic, or its better check all voltage??
I dont have home button schematic.

The U10 IC on the HB flex is for the “click” functions. This doesn’t have anything to do with the TouchID per se but it is possible that some damage to the flex in that area may also cause some issues elsewhere, I haven’t really looked at the wiring diagram that closely.
As Eigirdas suggests, I would closely inspect the flex for damage. If it is damaged near the connector end, you could look at the iMesa repair kit. Otherwise, only Apple can solve HB Touch ID issues.

Hot - short circuit. During screen repair most likely your HB flex cable/connector got damaged and makes short circuit that heats up copper traces. If you have microscope. Please run through your actual HB flex cable.
