What is Single-Sided PCB?

Single Sided PCB

Single-Sided PCB

A single-sided PCB is the simplest form of a printed circuit board. It has one layer with all circuit components mounted on one side of its layer.

It is also called a single-layer PCB. Single-sided PCB is mostly used for simple electronic applications.

It is made up of one substrate layer that forms the main structure or framework of the board.

On top of the substrate layer is a copper conductive layer. The board’s design circuit is done on the copper conductive layer. The circuit is then soldered on the copper layer.

A silkscreen is applied to the board to mark important details and values of the board.

A solder mask is applied to the copper layer to ensure smooth transmission of current through the circuit. The solder mask also protects the solder from corroding. It also prevents harmful materials from getting to the board.

What Is The Manufacturing Process of Single-Sided PCB?

Design the Compressor PCB.

The first step in the single-sided PCB manufacturing process is to design the board. You need to use excellent designing software to design the board to get a precise and accurate blueprint.

This will serve as a guide or roadmap in the manufacturing process. Remember, the quality of the board’s design is crucial to the success of the board.

 Design for Single Layer PCB

Design for Single Layer PCB

Print the Design

Once the design is complete, print the design with a plotter printer. In this process, the design is printed into a film capturing all the specifications of the board.

Produce Substrate

At this stage, the substrate that forms the base foundation or main structure of the board is produced.

Once this is done, you need to cover the substrate with a conductive copper layer and precure it in an oven. After this, etch the copper to create a very neat design of the laminate.

Remove Excess Layers

Here, unwanted copper layers are removed by passing them through a chemical solution. After this, use the optical punch machine to see if the layers are well aligned.

Drill the Board

With the aid of a computer-guided drill, drill holes in the single-sided PCB substrate. All excess copper should be removed afterward.

Plate the Board

The board is plated with thin copper and layered with tin materials. By doing this, you protect all outward layers of the single-sided board.

Etch the Board

After plating the board, you need to etch the board to take away unwanted copper. Once this is complete, a solder mask is applied to the board to give it a green color.

After this, you cure and coat the board before applying a surface finish to the single-sided board.


What Are The Components Of The Single Side PCB?

There are four main components of the single-sided PCB. They are substrate, a copper layer, solder mask, silkscreen.


The substrate is mostly made of fiberglass and forms the base foundation of the single-sided PCB. It provides massive strength to the board. All other layers are built on the substrate. You can call the substrate the main structure of the single-sided PCB.

Copper Layer

The copper conductive layer is applied to the substrate. The board’s circuit design is crafted on the copper layer. It also serves as a medium that transmits signals to other parts of the board. This functions like the nervous system of the human brain that transmits signals to all body parts.

Solder Mask

This polymer material covers the copper layer and soldered sections of the board. The covering of the copper layer with solder masks ensures the board’s system is not short-circuited as a result of copper layers touching each other.

Silk Screen

The silkscreen is applied on the single-sided PCB circuit to serve as a platform on which part details, manufacturer’s information, and other vital information are marked on the board.

You can see the part numbers, part references, test points, and symbol switch settings of the board on the silkscreen.

What Materials Are Used For Single-Sided PCB?

Single-sided PCB Manufacturers mostly use foil-clad and copper-clad laminates to produce single-sided PCBs.

Copper clad, copper-clad phenolic paper, copper-clad epoxy paper laminates are typical examples of materials used for manufacturing single-sided PCB.

When choosing the materials for your board, you need to consider key factors like electrical performance, feasibility, and processing specifications of the board. You need to also take note of the economic features of the board.

How Are Single-Sided PCB Maintained?

Manufacturers employ various techniques and steps in maintaining single-sided PCB.

In this section, we will look at some of the most important and popular steps in maintaining aboard.

Observe the board

For effective maintenance of the board, you need to first observe and understand the board. Critically study the board to understand how it works, its input and output interfaces, the functions it executes, and how its different control components are distributed.

Perform a Circuit Test on the Board

Right after critically observing and analyzing the board, you need to do an initial inspection and test on the board.

Even though this initial test may not help you find the real fault of the board, it is super important in providing you with good information that will help you repair the board.

Inspect the Components

Here, you remove the parts of the single-sided board from the circuit with a soldering iron and inspect them with standard inspection equipment.

It is important to note that it is not advisable to dismantle and remove the board’s components under normal circumstances. This is because dismantling the components may lead to damages to the board’s external integrity.

Fix the Fault

This is where you do the real maintenance work once you’ve discovered the board’s fault from the first steps. Here, you can repair the lines and replace faulty parts.

Test the board.

After maintaining the board, you need to test it on a computer to make sure it functions as expected.

How Long Does It Take To Produce Single-Sided PCB?

Production time for single-sided PCB is influenced by several factors. So, because of this manufacturers have different production times.

With that said, on average, it takes 3-5 to produce samples and 5-7 days for mass-producing single-sided boards.

To massively reduce production and delivery time, you need to produce the board in stock. The manufacturer needs to negotiate and agree with you on the delivery time.

What Procedures Should Be Followed When Ordering Single-Sided PCB?

Below are the processes you need to follow when ordering your single-sided PCB:

  • Determine the specifications of your single-sided board. Depending on the application of your board, you need to decide on the specifications of the board before attempting to order for your board.
  • Search for a reliable single-sided PCB. To do this, you can do a quick research on Google or Bingo by entering the keyword “single-sided PCB manufacturers”. Pick a Manufacturer with massive experience, at least 10 years. The supplier should use highly advanced equipment for their manufacturing.
  • Browse the website of your chosen supplier and select your preferred single-sided board that meets your application specifications. You can do this in the product catalog section of the supplier.
  • Connect with the supplier to make a former order request using the order form on their website.
  • Contact the customer services of the supplier for further instructions for your order.

What Software Is Used for Designing Single-Sided PCB?

Manufacturers employ various designing software to design single-sided PCBs depending on preference and quality of software.

Let’s have a look at some of the industry’s designing software:

What Qualities Do You Need To Look For When Choosing a Professional Single-Sided Manufacturer?

You must look out for these important qualities when choosing a single-sided manufacturer.


The first thing to look out for in a manufacturer is their professionalism. Your ideal single-sided PCB supplier should be professional in their operations.

One way to check if a manufacturer is professional is their certifications. Ensure you only order from a manufacturer with recognized industry certifications.


Experience is key in selecting a good single-sided manufacturer. Get to know the experience of the manufacturer in the board manufacturing industry. An ideal manufacturer should have at least 10 years of experience under their belt.

Experienced manufacturers employ experts, an experienced workforce, and the best technology in their board’s manufacturing thereby ensuring they offer quality single-sided boards.

Manufacturing technology

Due to the complexity of the manufacturing process of PCB, manufacturers need to use advanced technology and equipment to produce the quality board.

This is why you need to find out from the manufacturer’s website the kind of technology, equipment, and processes they use.

A reliable single-sided manufacturer should use cutting-edge technologies and test equipment for their production.


Again, the complexity of the PCB manufacturing process exposes it to unexpected failure and breakdown. This is why it is always safe to purchase from a supplier that offers at least a 1-year warranty for their board.

Suppliers who offer warranties for their board show they have massive faith in the capabilities of their board. It also proves they’re willing to replace or maintain your board for you for free when it breaks down during the warranty period.

After Sales Service

An ideal supplier should offer classic after-sales like training, repairs, etc. They should have good customer service you can contact quickly when you face a problem with your board.

You can read reviews of other clients on the supplier’s website to have a feel of the supplier’s customer and after-sale service.

What Causes Single-Sided PCB Failure?


Poor design happens to be a major reason why single-sided PCB fails. When you don’t fully understand the specifications of the board and design it to suit these specifications, the board may end up failing.

This means you need to spend time understanding the board’s specifications and its working environment. This will help you to create a quality board to meet its operational requirement.

It will also help you to choose the right materials for the board.

With this said, quality and industry-standard design software should be used for designing for excellent results.

After designing, the design should be checked and verified by an expert before fabrication begins.


Another common cause of single-sided PCB failure is its working environment. If the board is exposed to dust, high humidity, and extensive heat, it can fail.

The board should only be used in a suitable environment that aligns with its specifications. It should be periodically checked, cleaned, and maintained.

Manufacturing Defects

When there are poor or low-quality joints on the board, it can easily fail. Exposure to contaminants during manufacturing can lead to board failure.

Also, when the various layers or components of the single-sided board are not well aligned, it can cause it to fail.

Ensure that soldering is done perfectly to make the joints strong. Do not expose the board to various contaminants when assembling the parts.

The parts should be well aligned. Ensure there is structural integrity when assembling. Strictly follow standard industry fabrication standards to produce quality and lasting single-sided boards.
