How to add a new frame to iPhone lcd assembly?

So I am trying to refurbish screens my removing broken glass from an lcd and then replacing the glass using loca glue and everything and that has been going well, but the new issue is that I don't know how to apply the new frame. I am buying brand new frames from mentor.com but it's just not working out for me because I try using the double sided tape but that's super difficult to align and it doesn't work good at all. I tried using adhesive tape but that's even worse. I've done a few with super glue but that is just a risk because a lot of the time the glue squeezes out of the frame and makes the screen look like garbage considering I have t scrape it off so I have a working screen, but I can't sell it because it doesn't look new at all. If anyone has experience and knows what I can do please let me know. Thanks.
