Different Types of Printed Circuit Board PCBs

A printed circuit board (PCB) is a standard component in many different electronic devices. They are made from a variety of materials with the most common laminate, composite and fiberglass. In addition, the type of circuit board may vary with intended use.

Let’s take a look at the different types of PCBs:

Single side: This is the most typical circuit board and is built with a single layer or base material. The single layer is coated with a conductive material such as copper. They may also have a silk screen coating or a protective welding mask on top of the copper layer. A major advantage of this type of PCB assembly is the low cost of production and they are often used in mass produced items.

Front and back: there is the conductive material on both sides. There are many holes in the double sided plate to facilitate fastening of metal parts from the top to the bottom. This type of circuit board increases operational flexibility and is a practical option to build the most dense circuit designs. This board is also relatively cheap. However, it is still not a practical option for the more complex circuits and is unable to work with technology that reduces electromagnetic interference.

Different Types of Printed Circuit Board PCBs

Multi-layer: built with extra layers of conductive materials. The number of 30 layers or more means that it is possible to create a circuit design with very high flexibility. The individual layers are separated by special insulation materials and substrate plate. A major benefit of this type of PCB is the compact size, which helps save space and weight on a relatively small product. They are mainly used when it is necessary to use a high speed circuit.

Flexible: Designed with a flexible layer, but also available in single, double or multilayer boards. Flexible circuit boards are a great choice when you need to save space and weight when building a particular device. In addition, the flexible nature of the board can make them more difficult to use.

Rigid: built with a solid material and not flexible for its layers. This rigid circuit board is typically compact in size and capable of handling complex circuit designs. Signal paths are easy to organize and the ability to maintain and repair is quite simple.
