The printed circuit board (PCB) is an electric circuit with electronic components and a common feature in a wide range of devices, such as radar systems, radios and beepers. It is constructed in several different ways to match its intended use. Here are three main types of printed circuit boards:
The single side board is the least complex option and includes a one-sided layer of substrate. This board is built with the electrical components and parts attached to one side and on the other are the copper traces. The use of copper is favored because it is a great electrical conductor. The copper layer is often protected by a special solder mask. Also, a silkscreen coating is a further feature to help mark the different components on the board. It is a useful board for the most basic electronics and will be used by the at-home hobbyists in their first electronics projects. The single side board is relatively low-cost to manufacture compared to the other types. But, this board with its simple design means it has plenty of limitations and is far from being the most used in the industry.
