Choosing the Right PCB for Your Project: Single Sided vs Double Sided


Different types of PCBs vary depending on their complexity, cost and uses. Each PCB has its own specifications, which are applicable for certain uses. Among those PCB types, two PCBs are widely known and utilized in different electronic devices, equipment, and services. These two are known as the single-sided PCB and the double-sided PCB. Both are manufactured and produced for their own application. And now, with your project in mind, have fun learning as we explore the difference between single sided PCB and double sided PCB!


Let’s first discuss the importance of determining and choosing the right PCB type for your project. Sit back and take a look at the overview of both PCBs. Enjoy learning the difference between the two and the factors to consider when selecting between them!

Importance of Selecting the Right PCB for a Project

When doing a project, it is not enough that you are only doing it for the sake of accomplishing it. Since you already spend time doing it, put your best effort into it. Dig some information and background check what kind of materials you will use. These will help you attain the best result, giving your client a lot of satisfaction and fulfillment.

It is vital to learn selection when it comes to PCBs. Printed circuit board determination draws many advantages and benefits for your project. One of which includes fewer mistakes and repetition. When doing an electronic project, we always have that mindset that the best outcome will come out after a few trials, which is wrong. Trial and error methods will only put you in a hassle where the time spent doing it, the materials you used, the cost, and the effort you made will only come to waste. That’s why it is crucial to plan and choose suitable materials to use, especially in selecting the right PCB material for your project.

Overview of Single-Sided and Double-Sided PCBs

The two commonly known PCBs, single-sided and double-sided, are both beneficial for many uses. Single-sided PCBs are the easiest to produce among the other types of PCBs. It has a non-complex structure circuitry, which is why many people utilize this for simple and even large equipment types of electronic devices. The single sided PCB manufacturing process is the most convenient and straightforward one because it only has one conductive layer on one side and wiring on the other side. This type of printed circuit board can be used for different electronic applications needed for everyday life, which include printers, drives, vending machines, calculators, timers, radios, cameras, and supplies.

On the other hand, double sided PCB is a PCB type where there are two conductive layers on both sides. Having both sides covered with a conductive layer gives more space for circuitry. Different components can be properly allocated and aligned in the circuit board alongside the wiring connections. This type of printed circuit board is widely used in different sectors like automotive, aerospace, electronics, and medical. Double sided pcb applications come in different forms, like glass, ceramics, and metal

Difference between Single Sided PCB and Double Sided PCB

Difference between Single Sided PCB and Double Sided PCB

After learning its definition, let us now differentiate single sided vs double sided printing. Since these two are utilized in a wide selection of electronic devices, we might as well closely inspect the difference between the two to properly select what kind of PCB suits your project.

Conductive Layering

Single-sided PCB, from the word itself, only has a single layer of conductive material on its one face. On the other side, this is where its circuits or the aligned wiring are located. Double-sided PCB, however, has two conductive layers on both sides of its face. This allows for more space for wiring and other components.


Since the single-sided has only a simple design and layout, it is much more applicable also for basic electronic wiring design. In contrast, the double-sided can be applied to the most complex ones.


When it comes to density, the single sided PCB application is made for only low-density ones, while the double-sided PCBs are for high-density wiring layouts.

Production Rate

Since single-sided has a basic circuit design, it has a high production rate and can be produced in a short period. The double-sided, on the other hand, since it has complex circuitry, the production rate is not as high as single-sided PCBs.


When it comes to size, the single-sided occupies more space than the double-sided. Double-sided is more compact than single-sided because it has both faces with conductive material. Thus, wiring is compacted in both areas. Single-sided, however, only has one side for wiring; thus, it needs to be bigger in size.

Factors to Consider in PCB Selection

PCB Selection

There are different factors to consider when selecting between single sided PCB vs double sided, in which it includes the following:

Project Requirements and Specifications

The first factor to take into account when deciding between the two types of PCB is what is needed for your project. Picking a PCB just because you want it, because it’s inexpensive and affordable, or because it’s simple for you to work on is not wise. Naturally, you should rely on and base it on what is necessary and precisely required in your project. Enumerate all the requirements and specifications needed for your project and think about what will be the best and most suitable PCB type for it.

Circuit Complexity and Component Density

After considering the requirements and specifications, you will have to weigh the complexity and density of the circuit and components. Basically, in terms of less complex and low density, it is the single-sided PCBs, while the double-sided is on the contrary. If you think that after internalizing all requirements and specifications, either of the two can be used for the project, consider the complexity and density because this is what you will work on. You should weigh whether to use the less complex and the low dense or to use the much complex and high dense. Just always keep in mind that less complex circuits are easy to work on, but they can’t be used for more advanced technology and electronic devices. On the other hand, the more complex the circuit board, the more it is hard to work on, but it can be applied to more advanced devices.

Cost Considerations

Having both PCBs in your hand can be challenging to decide which one to use. Especially when you think about it, they both meet and pass the requirements and specifications. With this, you can consider which one will cost you more or will cost less for your project. Since it is quite obvious that the single sided PCB price is much less than the double-sided because of the materials needed for each PCB. Single-sided PCB only has one layer of conductive material while double-sided has both sides. Both PCB components comprise substrate, conductive, and solder masks. And since the double-sided has two substrate layers, it also changes the holes, and that will change the tracing. The higher number of tracings also equates to more cost value.


We cannot hide the fact that both single-sided and double-sided PCBs are greatly needed in the electronic and industrial sectors, especially with the advancement of technology. Whatever your choice will be, whether a single-sided printed circuit board or a double-sided PCB is to be used for your project, always take into account the best PCB you can work on.

Whether it will cost you more or it will cost you less, whether it is much more complex or less complex, still the choice is in your hand. The only thing you can do is select the best and work on your best to attain the greatest result.
