This is my favorite board holder. This one is specific for the iPhone 6plus and 6s-plus, but they are great for holding the board steady, allowing easy picking of underfill from between chips with tight clearances. I also like the cutout for holding a lifted NAND chip for cleaning it up after lifting. I also have the universal board holder and thought about discontinuing these individual ones--but they are my go to board holders. I will go out of my way to grab one of these when I need a board holder instead of the universal one right in front of me.
