About to replace screen/digitzier - sleep/wake sensor

I'm about to replace my wife's iPad Mini 4 LTE's LCD/digitizer (fused). The guide says to remove the connector with 6 solder pads on it, the home button, and some posts talk about a component that affects the sleep/wake function of the iPad.

Appreciate any help with some concerns:

1.) The 6 pads that need to be desoldered and resoldered, is it better to release it with a heat gun or use a soldering iron and peel it slowly away?

2.) How do I know if the replacement screen/digitizer has the component needed for the sleep/wake function

3.) Should the replacement not have it, what does the component look like and how do we remove it? Soldering Iron? Heat Gun?

Thank you all! (m _ _ m) (kneeling)

You want to remove it using a soldering iron with a small hoof tip, at the lowest temperature your solder can handle. Using leaded solder here will make your job a lot easier. Pop a small amount of flux paste on the existing joints before desoldering, too.

I'd recommend against using a heat gun - the kind of heat needed to melt the solder would destroy the plastic flex - or desoldering wick/braid, for a similar reason.

It'd be pretty obvious if the new display assembly doesn't already have the sensor, as there will be an exposed copper pad array in that location, ready for a sensor to be soldered onto it.

This is what the part looks like:

Any idea on where I could buy a replacement sensor?

Where in the world are you, Ryan? I'm based in the UK, so can only really make recommendations for here.
