No explanations at all? What’s the yellow film? Is that a heated surface or a heat gun off camera?

The yellow stuff is presumably Kapton (heat-resistant) tape, and it looks like there’s a heat gun off to the right. I’ve never seen Kapton tape used like this—my guess is that the technician is attempting to blow hot air between the connector and the flex without melting the plastic on either. But if the hot air is correctly applied (which takes practice), the heat will go to the metal and solder and not the plastic, and the plastic won’t melt.

One other comment: unless the SE is different, it’s an understatement to say “you don’t need to use a new home button.” If you DO use a new home button, fingerprint sensing won’t work. It relies on hardware that is underneath the home button itself, and is paired to the motherboard (the CPU, I think). If you can splice flex cables, you can cut the home button away from its original flex and splice it on to a new flex, retaining fingerprint sensing (at least I’ve seen this done on YouTube). Otherwise I think you’re out of luck.

That’s a lousy clip, or at least, not helpful for anyone who never did microscopic soldering before. At any rate, the “guide” is focusing on just showing the soldering part - but no background whatsoever. Show how the part looks before and after - how that thingy is related to the home-button at all —- something! you can’t expect anyone to use this movie, I think
