The printed circuit board (PCB) is an electrical circuit with electronic components and a common feature in a wide range of devices, such as radar systems, radios and beeps. It is constructed in several different ways to match the intended use. The good side with PCB is that you can easily find many PCB assembly services.
Here are three main types of printed circuit boards:
On one side
The single side frame is the least complex option and includes a single-sided substrate layer. This plate is built with electrical components and parts attached to one side and, on the other, traces of copper. The use of copper is favored because it is a great electrical conductor. The copper layer is often protected by a special welding mask. In addition, a silkscreen coating is an additional feature to help label the different components on the board. It is a useful board for the most basic electronics and will be used by home enthusiasts in their first electronic projects. The single side plate is relatively inexpensive to manufacture compared to the other types. But this plate, with a simple design, has many limitations and is far from being the most used in the industry.
The double-sided plate is the standard option for a wide range of applications. This plate has conductive layers of metal, components and parts mounted on both sides. In addition, the plate has holes to facilitate the connection of the circuits on each side. The different parts are connected using small cables that pass through the holes in the plate. The cables are welded in place to provide strong and reliable coupling. Another option to connect the two sides is the through hole technology. This method has the ability to create devices that run at faster speeds and with less weight. They use small cables that are permanently welded to the plate instead of using the separate cables.
The multilayer plate is built with two or more layers, each separated by insulation. The standard size is in the range of 4 to 10 layers, although there are plates with up to 42 layers. This is the preferred type of plate for the most complex electronic configurations. The different plates are connected by cables that pass through the individual holes. They are very useful to minimize problems with space and weight. The preferred use will likely include portable devices, space probe equipment, medical machinery, servers and computers.
