Hi, my ipad mini gold plate for touch connector on logic board got missing. how to fix it? thanks Edited: my ipad mini gold pins on logic board missing

IPad mini digitizer connector gets damaged from unplugging the screen by grabbing the long side of the connector. Grab it by the short side and you’ll never have this problem. once the connector is damaged, it is a straightforward job for mail in logic board repair or your local microsolderer. It is not a beginner job. once the pads are gone then it is a complex job that is quite challenging, but still doable for experienced microsolderers—although perhaps only for data recovery

Are you talking about the gold pins on the digitizer FPC connector on the logic board? If yes these are fragile and can pretty much break if you are unlucky. You’ll need to replace that connector through micro-soldering if it is damaged.
