Does digitizer replacement require soldering?

Hello,

I cracked the digitizer on my iPad mini 3 recently and am looking at replacing it myself using ifixit's front panel digitizer and their iOpener kit. I was wondering if this process will include any type of soldering? I have researched and watched numerous repair videos and some say you do need to solder and some say you don't. The digitizer appears to have all the connectors pre-installed, so I'm really hoping that no soldering is involved. Can anyone confirm this?

Also any tips and advice for a successful repair would be greatly appreciated.

Thank you in advance!
