Dear All
I start to try to design simple shield.
It' a shield with shift register on it.
I try to use an Eagle library for the shield, from Adafruit and Sparkfun ... to make sure that the pinheader is at the right place.
Any thing went good until I realize that all the pin-header pad is located at the bottom layer.
It means that all pin header will facing "UP".
As a shield, the male pin-header need to be faced "DOWN", and it means that the pads will have to be at the Top-layer.
My question , how to move the pads to TOP-Layer ?
Alternatively , how to make the pads exist in both layer ?
Sincerely
