Hi All- I've built a 100 pin BGA library part, A1 thru A11, B1 thru B11 and so on. In the F row, I have F20, F21 and F22 terminal numbers that have randomly appeared. No terminal that I can see, but just the number. I can delete them but they don't go away. They show up in my Part Type as unused pins. Any suggestions on getting rid of these?
