Drilling the board
All those dots in the copper areas are guide spots for drilling 1mm holes for the component leads. Some parts will fit in 0.8mm holes, but when drilling by hand, a little bit of extra clearance is useful. I'm using a tungsten-carbide drill bit which was designed for PCB use. If this was a fibreglass PCB, an ordinary drill would soon be blunted.
