I tore down my iphone when i removed the logic board a little piece came out .. has the number 160-5f, looks like it conects 2 things together. Update (02/06/2016)
this is what it looks like
This is the NFC signal conductor, hose beside the main camera.
I believe this is non essential unless you use apple pay nfc. I just lost mine replaced everything else and no problems so far. I’d like yo thank the community especially Tom Chai who posted this answer previously on another similar question. Thank you all. I actually lost this piece trying to take a picture yo put on the other post. Irony. Yep thats it.
