We use this solder paste for middle layer reballing on the iPhone X, Xs, and Xs Max. It’s a little stronger than the 138°C low melt solder, but doesn’t require as much heat to melt as the 183°C solder paste. It’s perfect for middle layer reballing. You really just need a dabble of this stuff on the end of your soldering tip to touch up any corroded pads. This stuff is perfect for that.
You’ll get 42g of solder paste.
