Single Sided PCB Board, Construction, Working, Features & Applications

Hello, friends, I hope all of you are enjoying your life. In today’s tutorial, I am going to explain single-sided PCB boards. PCB stands for printed circuit board; it is also known as a printed wiring board. When it was not common to use circuits, construction was a very difficult and time-consuming process and also costly, because it was done manually. Manually constructed circuits also had a shorter working life, and insulation of these circuits was difficult. After the availability of integrated circuits and different semiconductor materials, circuit construction became easy, and the printed circuit board also developed with time.

This circuit board made the construction of circuits too easy, cost-effective, and more reliable. Now on this board, we can easily make our circuits and projects. Almost all electronic devices are manufactured on this board, like mobile phones, calculators, and computers. There are numerous types of PCBs according to construction and use, like single-sided PCBs, double-sided PCBs, rigid PCBs, etc. In today’s post, we will have a look at single-sided PCBs, their manufacturing, working, uses, and some other related parameters. So let’s get started with what a single-sided PCB board is.

Introduction to Single-Sided PCB Board

• The single-sided printed circuit board is the basic category of a circuit board; on this board only one side is used for the production of different circuits, and there is only one side that has conductive parts for the construction of circuits.

• Due to simple construction, its price is also very low, making it the best option for new engineering students and project constructors to use.

• This category of circuit board was first invented in 1950, but due to its simple design and easy use, it is still used in different electrical and electronic projects.

• In 1956, when some engineers of Japan started to work on this PCB, this was the time it got boosted in electronic industries.

• The manufacturing of this board is very easy; it consists of copper on one side with the substrate over the copper coating for protection of the board’s solder mask wrap.

Construction of a Single-Sided PCB Board

• Due to its simple design, its manufacturing process is very easy, cost-effective, and less time-consuming. The substrate material of this board comprises fiberglass to increase the strength of the board.

• On this substrate material, different paths for current flow and component assembly are manufactured with copper; the use of copper is due to its best conductive power and lower cost.

• The length and diameter of copper paths rely on the manufacturing of the circuit, and users demand it be measured in ounces per square foot.

• Over the copper conductive path, a layer of solder mask is coated; this layer provides safety to copper paths from corrosion due to oxidation and moisture in the environment.

• On both of these two copper and solder masks, there is a third silkscreen layer that is employed for the drawing of different components’ symbols and characters; it makes sure users place components at the proper places and with the right connections.

Difference between Single Layer PCB and Double Layer PCB

• These are some main differences between the single-sided printed circuit board and the double-sided circuit board.

Single-Sided PCB Board

• This circuit board uses only one side for manufacturing o circuits, and on the other side different conductive paths are manufactured.

• On this board, there is only a single layer of conductive substance; the commonly used conductor is copper.

• There are three main layers assembled on this board: the first one is conductor material, the second one is a solder mask that protects the board from outer environmental conditions, and third one is silkscreen.

Double-sided PCB

• In a single-sided PCB board, there is one side used for the production of circuits, but in double-sided boards, both sides are used for the manufacturing of circuits.

• This PCB has conductive paths on both sides, including copper, solder mask, and silkscreen.

Single Layer PCB vs Double Layer PCB

Single-Sided PCBs

• It has conductive layers on a single side of the PCB
• It is best for less complicated circuit designs.
• It is a common part of low-density circuit designs
• Its manufacturing cost is less
• The larger volume of these boards can made in less time
• it does not have traces overlapping
• It can be easily repaired and debugged.

Double-Sided PCBs

• It has conductive layers on two sides.
• it is used for complicated designs
• it used fr high-density circuits
• Its manufacturing is costly
• Take time for larger volume production.
• It is best for advanced technologies.
• it has flexible features for routing and is difficult to repair

Single-sided PCB vs Multilayer PCB

• Single-layer boards are a simple type of PCB that has components on a single side. A single-sided board comes with single copper layers or conductive layers, and some boards have substrate layers.

• A multilayer board comes with components connected on both sides or has more than 3 layers according to design requirements.

Single-Sided PCB Board Advantages

These are some important benefits of a single-sided printed circuit board.

Lower Cost:

• As we discussed above, the physical structure of the PCB is simpler than other types of PCBs and needs less material, time, and practical experience. All these facts make it cost-effective.

Simpler Design

• Its construction and design are so simple that any normal designer can construct it without any special expertise. It is always preferred over other PCBs due to its simple design and production in fewer time intervals.

• Most PCB users prefer it due to its simplicity in design, and it is the best choice for new users of this board.

High Volume:

• Due to their simple design, these circuit boards are manufactured in large numbers, and due to the high quantity, their price automatically decreases.

Short Lead Time: 

• Another benefit of this board is that it can be manufactured in very little time and in large quantities, which makes it an instant option for users of PCBs.

Single-sided PCB Disadvantage

• While it has some advantages, there are some disadvantages that every user should keep in mind.

Simple Design:

• The simple and easy manufacturing design of a single-sided PCB makes it effective for users, but it also has some limitations.

• For such circuits, large numbers of components to be assembled need large space and more connection points that are lacking on the board.

• If we construct circuits on this board with a large number, there is a chance of short circuits and damage to devices if proper insulation is not done.

Slower Speed 

• The minimum number of components joining points also disturbs its speed and power. Due to its lower operating speed, it is not favorable for such applications where a large number of connections are needed.

Large Size:

• For the addition of a large no of components, there is a need to increase its size which also increases its weight and cost.

Single-Sided PCB Board Pros

• Before the implementation of single-sided PCB, you should also study some factors either it fulfills the requirements of your projects or not. And you should also note these pros and cons before choosing this category of printed circuit board.
• Its price should be less.
• Its design should be simple and easy to handle.
• It has a smaller lead time.

Single-Sided PCB Board Cons

• Its design is not suitable for complicated projects so its best for these circuits.
• Its working capacity is also less.
• Its operating speed is also lower.
• Due to its large size, it is expensive.
• Due to large components assembled on a single board, its weight is also large.

Applications of Single-Sided PCB Board

• These are some applications of a single-sided printed circuit board.

• Due to its low price and easy construction, it is mostly used for different engineering projects.

• As other types of PCBs are growing fast, single-sided PCB importance cannot be denied for simple circuits.

• In our home, appliances like coffee makers are constructed with a single-sided circuit board.

• Calculators, mobile phones, radios, and light-emitting diodes consist of these boards.

• The solid-state driver also consists of this PCB, and different sensors are also constructed with a single-sided PCB board.
