I am designing a PCB that has will hold an Arduino Micro, as well as other components. One of the electrical engineer mentors that are overseeing the board development has told me to increase the copper pad size/decrease the hole size for the pin headers in order to have an overall larger pad surface area. He told me to do this because it lowers the risk of the pads coming off in the event that we have to desolder the Arduino from the PCB (dead board, etc.).
Currently, the holes and pads are circular, with the total edge-to-edge exposed copper diameter at 2mm, and the hole size diameter at 1mm (picture below).
Is there a need to make the copper pads larger in the case of a desolder, or will keeping the pads their current size be fine after a desoldering?
NOTE: I cannot make the pin header hole much smaller, as they are square headers with a 0.65mm side length (corner to corner length is just under .92mm), but I can make the pads slightly larger if absolutely needed.
