Single-Sided PCB Circuit Board

The Most Important Things You Need To Know About Single-layer PCB


In this article, we will elaborate on the definition, type, cost components, structure, advantages and disadvantages, manufacturing process, and raw materials of single-sided PCB. Finally, we will introduce the application of single-sided PCB and the differences between single-sided PCB and double-sided PCB. And how to choose between single-sided PCB and double-sided PCB.


What Is Single-Sided PCB Circuit Board ?

For Single-sided PCB, also called Single Layer PCB, One Layer PCB, 1 Layer PCB, the components are on one side, conducting wires are, on the other hand, single-sided PCB is the most simple and basic PCB board. Because the wires only appear on the one side of them so, we called Single-sided PCB. Because the single-sided PCB has many strict restrictions on the design circuit (because only one hand, the wiring cannot cross and must move around the individual path), so it only used on earlier channels.

The History of The Single-sided Printed Circuit Boards

With the appearance of the electronic transistor, single-sided PCB was developed in early 1950, which is mainly manufactured in the USA. Single-sided PCB was manufactured by copper etching directly at that time. From 1953 to 1955, Japan uses imported copper to make out paper phenolic aldehyde copper substrate, and apply mainly on radio products. In 1956, single-sided PCB technology was made significant progress with the appearance of professional PCB manufacturers from Japan. In the early stage, copper substrate mainly used paper phenolic aldehyde, but because paper phenolic aldehyde with the factors of low electric insulation, bad solder thermal stability, twist issue, etc., paper epoxide resin and glass fiber epoxy resin was developed soon after. Currently, paper epoxide resin is widely used in consumer electronics.

Characteristics of the Single-sided Circuit Board

Single-sided PCB diagram mainly used Network Printing(Screen Printing), that is, resist on the copper surface, After etching, mark the welding resistance, and then finish the hole and the shape of the part by punching.

Fundamentally, single-sided and double-sided Printed Circuit Boards serve the same purpose. Both serve as catalysts for electrical connections between components. However, some key differences set them apart from each other. More specifically, they differ in the costs associated with production and development processes, as well as ampacity differences.

The Production of Single-sided PCBs is not a Challenge.

There is no challenge for PCB manufacturers to produce single-sided PCB, and the technology is quite mature nowadays. The main focus of PCB manufacturers is how to control production costs and save more value for customers.

Types of Single Layer PCB

Single-layer Rigid PCB Board

It is the type of a single layer PCB that is made up a rigid material such as fiberglass. These PCBs are inflexible and prevent the circuit from bending and breaking. Currently, these are used in different types of devices, such as in calculators and power supplies, etc.

single-layer Flexible PCB Manufacturing

It is the type of a single layer PCB, which is mode out a flexible material instead of a rigid material, and for this purpose, plastic materials are used. It has so many advantages over a single layer rigid pub, but its fabrication cost is so much high.

It is the type of a single layer PCBs which is used for high-frequency circuits, usually in gigahertz. These PCBs are made out a Teflon or polyphenylene oxide (PPO) material. During choosing high-frequency single layer PCB, many aspects are kept in mind, such as dielectric loss, thermal expansion, and water absorption, etc.

Single-sided High-frequency PCB production

Single Layer High-Frequency PCB

It the type of single-layer PCBs which is made out of the combination of plastic and fiberglass. Both materials are combined into a single layer. It has so many advantages over single layer rigid and flexible PCB, such as it reduces the weight and size of the overall PCB.

Single-sided Aluminum PCB Manufacturing

It the type of single layer PCB which is made out with aluminum material substrate. The design of this PCB is almost the same as copper backed PCB, but the only difference is that in these PCBs, aluminum substrate is used instead of copper. Aluminum backed is used with thermally insulating material for transferring the heat from insulating material to back.

Advantages and disadvantages of single-sided PCB

Advantages of Single-Sided PCB

Single-sided circuit boards are considered to be one of the best choices for a wide range of applications due to the advantages that it provides. Here are a few benefits of single-sided printed circuit boards:

  • Simple and easy to design and install
  • Lower cost, especially for high volume orders
  • Easy drilling, soldering, de-soldering, and components inserting process
  • Lower probability of manufacturing issues, such as short-circuiting and producing noise
  • Parts are installed at only one side, require the lower jumper to compensate the circuit
  • Widespread, universal, and easily understood by most PCB manufacturers
  • Less time for fault tracing and repairing

Single Layer PCB Disadvantages

Despite their cost advantages and other perks, single-layer boards are not the right choice for every project due to the limitations they have, which include:

  • Simplistic Design: The simplicity of single-layer boards’ is one of their most significant benefits, but it’s also a substantial limitation. For more sophisticated devices that require a higher number of components and connections, a single layer does not provide enough space or power. If wires cross each other, the device won’t function properly, so the board must have enough space to accommodate everything. More elaborate designs just can’t fit on single-sided PCBs.
  • Slower Speed and Lower Operating Capacity: The limited number of connections on these boards also affects their power and speed. These less-dense designs are not as robust as those with more circuits and have a lower operating capacity. They might not have enough energy for some applications.
  • Larger Size and Higher Weight: To add capabilities to a single-sided board, you need to expand its dimensions rather than add another layer, as you could with you a multi-layer PCB. You could use multiple separate boards, but one multi-layer board could likely handle the same requirements. Increasing the size or number of boards in a device also increases your final product’s weight.

Single layer PCB Raw Material

The base material, which is also named as substrate, is composed of insulating fiberglass which gives PCB strength and compact look. The nature and type of base material define if the board is going to be Flexible PCB or Rigid PCB.

The single-sided printed circuit board substrate as follows.

  • Fr4 Grade Fiberglass Laminates
  • Aluminum
  • Copper base
  • Cem 1
  • Cem 3

Construction of Single Sided PCB

Above substrate, there lies a copper layer which provides conducting path for various components on the board. The copper thickness is different for different councils, depending on your needs and requirements, and is defined in ounces per square foot.

On the top of copper foil, there exists a solder mask layer. This layer is mainly used for protection and makes the copper foil insulating, which helps in avoiding the conduction in case direct contact happens with some conducting material.

On the top of all layers, there exists a silkscreen layer that is mainly used for adding symbols and characters on the board so an ordinary person can anticipate a clear understanding of the board.

What Goes Into Determining single-sided PCB Costs and price

No matter whether manufacturing a single-sided PCB, double-sided PCB, or multilayer PCB, three main cost categories exist Primary production costs, dependent costs, and overhead costs.

Often, single layer PCBs are used for simple devices and usually cheaper than multilayer PCBs.

Multilayer PCB has one or multiple conductor patterns inside the board; this increases the area available for wiring. Multilayer PCB, such as 4 Layer PCB, 6 Layer PCB, and 8 Layer PCB is usually used for more complicated devices. For example, smartphones use 12 layers due to the various demands of the circuit. As a result, multilayer PCB circuit boards are more expensive.

You can break them down into the following categories:

Primary or Fixed Production CostsSecondary or Dependent CostsOverhead Costs
Board SizeToolingFacility
Number of PCBs produced in a production runLayout – trace design, hole size, and hole countLabor – salaries and benefits
Number of layers beyond double-sidedLaminationEquipment
