Soldering Question


#1

Below in this tutorial for buttons LB and RB it says, has anyone just soldered onto those points without cutting back the plastic to? or do i need to cut off the plastic to reveal the copper?

The only 2 buttons you do not need to scrape any rubber away from are the Right/Left bumper buttons. They have metal exposed already you can solder directly to, and you can see that from the picture.
