Forth Step: Drilling the PCB

        

       At the Electronics Room, only one hand drill was available to use. So we let other groups to finish first and we just waited for our turn. Finally,its our turn, I let Jorrel do the drilling. We patterned the holes from the given design and size of the PCB. The purpose of this holes is where to attach or fix the components (soldering) and where to insert the wires for connecting to other components.

     Drilling with 0.8mm drill bits can be a bit tricky as it's easy to break the drill bits. Always hold the drill straight and do not bend it when the hole has started. Putting a soft block of wood under the PCB provides a good base to drill into.

Fifth Step:  Placing the Components on the PCB

    Jessica placed the components [consist of four diodes, two capacitors and a resistor ]according to the given pattern or design forthe printed circuit board.
