Printed Circuit Board Fabrication

Sprays that meet too far away from the board lose energy, and will not develop as well. If the sprays do not overlap at all, those areas that they do not touch will not get the spray pressure required for good developing. Note that this spray pattern issue is also very important in the first rinse, to assist in removing the resist foot.

Circuit Science Projects for Elementary and Science Lesson

A circuit is a path that electricity flows along. If the path is broken, it is called an open circuit and the electrons can't flow all the way around. If the circuit is complete, it is a closed circuit and electrons can flow all the way around from one end of a power source (like a battery), through a wire, to the other end of the power source.

Stripboard is used to make up permanent, soldered circuits. It is ideal for small circuits with one or two ICs (chips) but with the large number of holes it is very easy to connect a component in the wrong place. For large, complex circuits it is usually best to use a printed circuit board (PCB) if
