Cutting a motherboard can become tricky.
A motherboard, essentially a large PCB board, is manufactured of a very hard fiber resin material. It can be very difficult to cut. If you break the shell on a piece of equipment and you decide to place the motherboard into a different sized casing you may need to cut down the size of a motherboard to fit it inside the casing. If this is the case, you have a couple of options to try.
Instructions
Straight Line Cut
1. Draw a straight line onto the motherboard with a marker and a ruler.
2. Inspect the copper contacts on the bottom of the PCB board to ensure you will not cut into the copper contacts. If your line runs over any copper contacts, you must move the line.
3. Place the ruler back over the line you drew and hold it in place with one hand.
4. Score a line into the motherboard with a very sharp utility knife. Be careful; do not cut the hand holding the ruler. Run the line along the ruler several times until you cut through approximately 25 percent of the PCB board. Grip the motherboard on both sides of the scored line and then break the excess portion of the board off.
Curved Cuts
5. Draw the outline of the area you need to remove from the motherboard with a marker.
6. Inspect the bottom of the motherboard to ensure your line does not run over any copper surface. If it does, you must move the line.
7. Position the motherboard flat onto the surface of your band saw table and then turn on the band saw.
8. Cut along the outline you drew onto the motherboard with the band saw blade. Cut slowly and grip the motherboard firmly to ensure the blade does not rip the PCB board out of your hands.
