What are general current limitations when using PCB line width of 10, 12, 16 and 24mils? I'm not really sure of the thickness of material used by my PCB manufacturer, but it looks like this (if it's helpful):

Default copper is 1oz/ft^2, try a pcb trace calculator:
If that's the case, 10mils seems fine to drive 8x6 button matrix, 8x4 LED matrix (220ohms resistors + ULN2803) and couple of multiplexers.
