Home button doesn't click after repairing lightningconnector / battery

Hey there ifixit'ers

I just replaced the battery and lightning connector in my iphone 5 using the ifixit guides and tools.

When I tighten the left side pentalobe screw in, the home button stops working.

If I leave it loose and pry it up a little bit, it works fine.

I imagine it has to do with those gold terminals on the left side, but I can't understand why tightening the connection makes it fail and loosening it makes it work fine again.

In the meantime, to avoid dust, I enabled assistive touch and tightened the left side of the screen.

What should I do when re-assembling the phone to ensure the home button connects properly and works?

It worked fine before doing the repair.
