Pcb Layout

When planning the layout of a printed circuit board (PCB), it is important to consider who will be using the board once it has been manufactured. If your PCB is a simple one to be used solely by you, then perhaps you needn't be overly thorough in labeling the different systems and sub-circuits. If you follow regular conventions, or if you don't plan to use the board for a long time, there's no need to be disciplined in the layout of your board.

Chances are, however, that it would behoove you to follow some particular guidelines in laying out your PCB designs. The first advantage to following a strict layout guideline is that other people can follow your design and add components to it. If you are creating a circuit board for anything other than the most personal use, it makes sense to follow a logical layout so that other workers will know where to solder resistors, integrated circuits, capacitors and other components.

Logical layout guidelines also aid in troubleshooting procedures. If you have a circuit that is not working properly, a well-laid-out board can allow you to bypass a particular sub-circuit to perform tests. If your layout does not follow a particular plan, it can be difficult to ascertain the problem areas.

Software and PCB Layout

Computer-aided design (CAD) applications can greatly facilitate the proper laying out of printed circuit boards. Most of these programs will automatically lay out a circuit in an efficient and logical manner. By using one of these applications in the design of your PCB, you can be sure to create an effective, thorough and comprehensible layout.
