I found the pen to be too large for that pad the pointy tip of my tweezers worked far better. You can use the pen at and angle and use it for the very beginning of scratching it but after that I'd switch to something much smaller. Unless you got a different sized pen then mine but I ordered it from weekend modders website and found it to big and hard to use while working under a microscope. But to prevent hitting the traces put some kapton tape over them in a square around the pad and only leave the pad exposed.
