This is a type of printed circuit board that only contains a layer of conductive material on one side and the other side is used to incorporate different electronic components. I will try to cover all aspects of the unilateral PCB so that it does not have to go anywhere and find all the information in one place. We analyze and explore what it is and what its main applications are.

Construction of Single-sided PCBs

The base material, also called a substrate, is made of insulating glass fiber that gives it strength and a compact appearance. The nature and type of base material determine whether the plate will be a flexible printed circuit board or a rigid printed circuit board.

On the substrate, there is a copper layer that provides a guide path for different components on the board. The thickness of the copper is different for the different tables depending on the needs and requirements and is defined in ounces per square foot.

At the top of the copper sheet, there is a welding mask layer. This layer is mainly used for protection purposes and makes the copper sheet insulating, which avoids driving in the event of direct contact with a conductive material.

At the top of all levels, there is a screen layer that is used primarily to add symbols and characters to the board, so that a normal person can anticipate a clear understanding of the board.

Single Sided PCB or Double Sided PCB?

The PCB you choose will depend on your needs and requirements. Sometimes single-sided PCBs are more suitable for design than double-sided PCBs and vice-versa.

Before choosing a type of PCB for your project, you should keep in mind that unilateral PCB designs are more difficult to route than double-sided PCBs, but here are the reasons why you should strive to and select circuit boards on one side on the other.

  1. If you are an amateur or a student and want to do PCBs at home, it is much easier to develop one-way PCBs at home than to develop them at home.
  2. Since you are a manufacturer and you really want to reduce costs and produce a single-sided PCB, this is a cheaper process. In terms of costs, the production of printed circuit boards on one side is cheaper than the production of two-sided printed circuit boards.
  3. Almost all HVAC systems use unilateral printed circuit boards because they are more reliable and economical and do not compromise the overall quality of the product.
  4. The use of through-hole technology in single-sided PCBs still has its drawbacks and limitations, because the conductive layers, lines and pads remain on one side of the PCB, but still an inexpensive process. Multi-layer printed circuit boards are also used in many applications where single-sided and double-sided circuit boards do not meet the requirements.

Advantages of the one-sided circuit

  • This is an ideal option for low-density projects.
  • Extremely economical in nature.
  • It’s just a production process and has very few manufacturing problems, making it an ideal option for most professionals.
  • You can also work online with PCB design services. Here are the best PCB design services online


Printed circuit boards on one side are widely used in many electronic applications, from simple circuits to intermediate circuits to complex circuits. The following are some applications that you can use:

  • Camera systems
  • Calculators
  • Coffee makers
  • LED lighting
  • Sensor products
  • Power supplies
  • Radio and stereo equipment
  • Timing circuits
