A printed circuit board (PCB) is a standard component in a variety of electronic devices, such as computers, radar, beeper, etc. The most diverse materials are laminate, composite and fiberglass. Additionally, the type of circuit board may vary depending on the intended use. Let's take a look at the five different types:
One-sided – this is the most common circuit board and is built with a single layer or base material. It is coated with a single layer copper coated, conductive material. There may be silk paint or protective soldering masks on top of the copper layer. These advantages of PCBs of this type are low manufacturing costs and are often used in bulk products
Two-sided – this is very similar to a one-sided but conductive material on both sides. There are many holes on the deck to make it easy to fasten the metal parts up and down. This kind of circuit board increases operational flexibility and is a practical option for denser circuits. This forum is also relatively low-cost. However, this is still not a practical option for the most complex circuits and can not cooperate with electromagnetic interference suppression technology. Usually used in Amplifiers, Performance Monitoring Systems and Test Equipment
Multilayer – Multi-Layer Circuit Board is equipped with separate layered conductive materials. The large number of layers that can be 30 or shorter allows to create a very flexible circuit. Each layer is separated by separate insulating materials and substrate sheet. The great advantage of this type of board is the compact size that helps save space and weight in a relatively small product. In addition, they are mostly used when high speed circuits are required.
Flexible – this is a very versatile circuit board. This is not only designed with a flexible layer, but also available in single, double or multilayer boards. It is a great choice to save space and weight when building a particular device. Furthermore, they are evaluated for high ductility and low weight. However, the flexibility of the board makes it more difficult to use.
Rigid – rigid circuit board is built with solid, non-elastic material for its layers. They are typically compact in size and able to handle complex circuits. In addition, signal paths are easy to organize and maintenance and repair capabilities are quite simple.
