If you are involved with anything electronics, then you must understand what printed circuit board or PCB is because every piece of electronics have these boards inside for them to work. PCB is a basic part of electronic gadgets and equipment like radars, computer, cellphone, and so on. PCBs come in different type of materials such as fiberglass, composite, and laminate. Understanding the types of printed circuit board can help you understand more about PCB design as well. Here are the different types of printed circuit boards:
The single sided is the most common type of PCB. It is built with a single base material, which is usually coated with copper, a conductive material. On top of the copper layer is a solder mask or a silkscreen coat that protects it. This type of PCB has cheaper production cost, which makes it great for items that can be mass-produced.
From its name, the double sided PCB is pretty much the same as the single sided, only that you can find on its both sides the conductive material is placed. You’ll find that the board has many holes, to easily attach metal parts. This type of PCB is more flexible. If you want to create circuit designs that are dense, the double sided PCB is a good option for you. However, this board may not be the best option if you will have complex circuits. The double sided PCB does not work also with electromagnetic interference-reducing technologies. Testing equipment, amplifiers, and power monitoring systems are examples of electronics that use double sided PCB.
This circuit board comes with more layers of conductive materials that could reach for up to over thirty layers. This allows the creation of a very flexible circuit design. You’ll find in between each layer substrate board and special insulating materials. What’s great about this PCB is its compact size, which makes it suitable for small products. Multi-layer PCBs are also used when high-speed circuit is required.
This circuit board offers great versatility with a flexible layer. It is also designed in single, double or multi-layer circuit boards. When building a certain device that requires small space and weight, the flexible PCB is a great option. Furthermore, this type of circuit board has low mass and high ductility. However, this board is also difficult to use because of its highly flexible nature.
This type of circuit board has layers with materials that are solid and non-flexible. Rigid boards have sizes that are compact. When it comes to complex circuit designs, rigid boards are best suitable to use. Moreover, it is easy to organize the signal paths of these circuit boards. They are also easy to repair and maintain.
