a. Thermal reliability
b. Temperature reliability
c. Heat transfer
d. Signal performance
e. Mechanical properties
- PCB size: the size of the PCB in terms of the number of circuit boards required to make it up will affect the price.
A single-sided PCB will therefore be slightly cheaper as compared to other kinds of PCBs due to its components.
- The number of layers: the number of layers affects the price of a PCB thus PCBs with more than one layer will tend to be more expensive as compared to single-sided PCB.
- Finish: the costs incurred to obtain the final finish of a single-sided PCB will determine the price. Single-sided PCBs with high-grade finishes tend to be more expensive as they are more durable.
- Size of hole: the sizes of holes in a single-sided PCB are a determinant of the final cost. More holes are challenging to drill due to the thickness and tinniness of the circuit board thereby causing the price to increase.
- Minimum trace and space: single sided PCBs that are free from the threat of overheating and have sufficient trace width in the board design are relatively expensive.
- The thickness of the PCB and Aspect ratio: the thicker the material used the costlier the PCB.
A PCB with a larger aspect ration is also costlier than that with a lower aspect ratio.
- Custom or unique specifications: customization of the PCB also means higher customization expenses because of the special skills and tools that will be required in production.
- Some of the customizations of PCBs include contoured edges, side plating, solder mask clearance among other specifications.
Which Conductor Materials can you use on Single-Sided PCB?
The various components of PCBs are made from different materials. These may include:

- Lack of component mounting holes.
- Components on the PCB are not reinforced.
- Poor assembling strength of the components.
- Poor solder joint work and cracking.
- Heat capacity is unbalanced.
- The maintainability of the pads is poor.
- When the pad spacing is too large affecting the placement accuracy of the components.
- When the width of the pad is too large affecting the component drift range and leads to component deflection.
What is Poor Single-Sided PCB Solder Mask Film Design?
Poor single-sided PCB mask film designs occur when:
- When the pad is connected to the hole and the connecting vias are not soldered leading to solder joint defects.
- When the solder resist pattern is not per the solder joint distribution designs. This leads to the short-circuiting of the PCB.
- When the solder mask pattern size is too large resulting in non-resistive soldering.
- When there are no solder masks under the components. This may lead to a short circuit of components.
What are the available Surface Finish Options for Single-Sided PCB?
PCB surface finish
The surface finish is the metals that protect the copper used in single-sided PCBs from elements.
PCB surface finishes also ensure the copper does not oxidize and corrode.
There are different types of finishes and al; provide different types and levels of protection.
Some of the finishes available include:
- Immersion Gold (ENIG): also known as electroless Nickel immersion Gold and one of the preferred finishes available in the market.
- Immersion Silver (IAg): usually applied to the PCB via chemical displacement. It is a less costly finish compared to ENIG and diffuses easily with copper.
- Immersion Tin (ISn) is preferred because it is applied directly to the base metal of a PCB. It is the most affordable of the available finishes.
- HASL: this finish utilizes tin or lead and creates a thin protective covering on a PCB. HASL is less used in PCB production because of not meeting RoHS standards.
- Pb-Free HASL: are increasing in popularity because of their environmentally-friendly capabilities. They use copper that is mixed with nickel to create a protective coating.
- OSP: also known as Organic Solderability Preservative is an environmentally friendly finish. Uses an organic compound to bond with copper naturally.

Does Single Layered PCB have a Single Loop?
The single-layered PCB has the power and ground layer on the same side of the PCB board.
Together with form a large distributed capacitor which enhances high frequency for the power supply.
The independence of the power and ground layer minimizes the area of signal loops.
What Track Layering PCB has Signal Loop?
Signal loops generate noise in electric circuits as a result of large currents in ground planes.
Some of the factors that lead to signal loop include:
- Signal degradation due to uncontrolled line impedances such as encountering changes in impedance of the line.
- Signal degradation due to other impedance discontinuities such as encountering a via in its path.
- Signal degradation due to propagation delay. Signal line lengths and inversely proportional signal speed cause signal loops.
- Signal degradation due to signal attenuation caused by conducting trace resistance.
- Signal degradation due to crosstalk noise that occurs when there’s a fast voltage on a signal line.
- Signal degradation due to power and ground distribution network. When output signals and internal gates switch states, currents through power and ground rails/paths/planes change.
This causes a voltage drop in power and ground paths.
- Signal degradation due to EMI/EMC. This occurs as a result of faster signal rise times.
- Signal integrity issues due to via stub and trace stub.
- Signal integrity issues due to ground bounce. This occurs when excessive current makes the ground levels shift from the original.
What is Track Layering in Single Layered PCB?
Track layering in single-sided PCBs is the process of putting copper layers on a PCB board in a well-defined sequence.
Tracks connect holes where component leads and wires are soldered on.
Single-sided PCBs have components placed on one side while the copper tracks are placed on the opposite side of the PCB board.
Tracks run in any direction but cannot crisscross one another.
If tracks require to Crisscross one another, a bridge is used on the component side of the board.
Where is Power and Ground Pane in Single Layer PCB?
You will find the power and ground plane on the top side of the single-sided PCB.
It is much simpler connecting components to the plane to route the power and ground trees with traces thus much better installing the power and ground planes on the top side of the PCB.
Solid power and ground planes are known to be good in reducing EMI emissions and thus enhance the quality of the signal on the traces.
What are the Performance Features of Single-Sided PCBs?
Some of the performance features of single-sided PCBs include:
- Dielectric constant: this indicates the electrical performance.
- Flame retardance: important for underwriters laboratories flame suppression standards.
- Higher glass transition temperature (Tg): critical in high-speed applications.
- Mechanical strength includes shear and tensile and other components that are determined before testing a PCB.
- Thermal performance: tested in various working environments of the PCB.
- Dimensional stability: testing the material how it moves, consistency, manufacturing, thermal circles, and how it works under humidity.
What is the Best Material for Single-Sided PCB?
Some of the materials used in the fabrication of single-sided PCBs include but are not limited to the following:
- FR4 epoxy laminate and prepreg: these materials are the most used in the fabrication of PCBs. They have good thermal, electrical, and mechanical characteristics.
Some of the materials that make FR4 include glass cloth and epoxy resin.
- Polyimide laminates and prepreg: they have high temperature and electrical performance properties.
They have fewer expansion capabilities and are stable during thermal cycling.
- Teflon laminates and bonding plies: are ideal for fast circuitry applications.
They can be coated on glass fabric and used as an additive to improve mechanical properties.
- Flexible laminates: can easily be folded without losing electrical continuity. They are made from high-temperature materials such as polyimide, liquid crystal polymer, polyester, and PEN.
- Others: these include BT, cyanate ester, ceramics, and blended systems. They combine resins to get distinct electrical and/or mechanical performance characteristics.
Apart from Single-Sided PCBs, What other Types of PCBs are there?
Some of the other types of PCB available include:
These PCBs have a series of more than three layers.
They come in a variety of sizes, as small as four layers to as large as ten or twelve.
The circuits and components are usually connected either by utilizing vias or by using a surface mount.
Mult layer PCB
These are made of a solid substrate of printed circuit boards that enables the board not to bend.
To find a good example of a rigid PCB you need to open up your computer.
The motherboard inside your computer is a good example of a rigid PCB.
This type of PCBs makes up the largest number of PCBs manufactured because of their use in most electronic devices.
These are made of movable materials that can flex and move.
Such materials may include plastic or reinforced rubber.
They come in single, double, or multilayer formats and cost more for fabrication.l
These use a combination of multiple layers of flexible PCBs attached to several rigid PCB layers.
They combine the best of both.
Rigid –Flexi PCBs are advantageous in that they have a lower parts count compared to traditional rigid or Flexi boards.
They also allow for a more streamlined design and reduced board size and weight.
This refers generally to a PCB design element rather than a constructed PCB model.
They are circuit boards designed to transfer electrical currents and signals over one gigahertz.
The high-frequency PCB materials may include but not limited to:
- FR4- grade glass-reinforced epoxy laminate
- Polyphenylene oxide (PPO) resin
Aluminum Backed PCBs
It is also referred to as metal base PCB, it consists of copper and a thin thermally conductive and electrically 4insulating layer that covers the copper foil and metal base.
The aluminum backed PCB is usually divided into three layers which are the circuit layer, insulating layer, and base layer.
The main use of aluminum-backed PCB is providing heat dissipation solutions, especially where high temperature is involved.
Why does Single Layered PCB have Reduced Noise on Power Cord?
Single layered PCB signals are of superior quality; this is achieved by the reduction of propagation and distortion levels.
The method of laying components on the PCB board enhances higher levels of signal integrity.
Also, it reduces interference levels by reducing the inductance of the power wire and ground wire, thus reducing the noise voltage.
Do you need Vias in Single Layer PCBs?
Yes, you will need a via in single layer PCB especially if you need to bridge tracks on a single layer PCB.
Vias are the copper cylinders on a single-layered PCB that are used to electrically join traces on the board of a PCB.
You will mainly find them in holes drilled in a PCB.
Because components tend to be clustered together and have to be routed on the other layers, they need vias.
Vias connect all components for all the signals to go from the component to the signal layer.
How do you Test Single Layer PCB?
You can use the capacitance test to test a single-layered PCB.
A capacitance test is used to check if a PCB is working.
It tests for opens and shorts by sending a charge on the trace or plane and measures the induced capacity.
The induced capacity is the resistance that occurs as the current flows through a trace.
What are the Quality Standards for Single Layer PCBs?
Some of the quality standards for single-layered PCBs include:
- Underwriters Laboratories (UL) ratings.
- European Union’s Restriction of Hazardous Substances (RoHS) standards.
- Military performance certification: Mil-PRF-31032
- UL certified for flexible and rigid-flex constructions

How does Single Layer PCB compare to Multilayer PCB?
Some of the factors that distinguish single-layered PCBs and Multilayered PCBs include:
- Maximum dimension: you have to consider what will be the maximum dimension of the PCB. A multilayered PCB has more functionality than a single layer PCB.
- Level of functionality: this refers to the level of functionality you need. If you have a more complex level of functionality you will need a multi-layered PCB.
- Durability: a multilayered PCB is more durable than a single-layered PCB.
- Budget: if you go for a lower budget PCB the single layer PCB is for you. Due to the more complex nature of a multilayered PCB, it tends to attract a higher price tag.
- Turnover time: this refers to how quickly you need your PCB boards from the manufacturer. A single layer PCB has a fast production lead time compared to a multilayered PCB.
- Layers: a single-layered PCB has just a single layer while a multi-layer can have two or more layers stacked together to form a single PCB.
Does Cheap Single-Sided PCB Imply Low Quality?
Not really, several factors bring the price of single-sided PCBs down.
- Technology: Investing in modern technology reduces manufacturing cost hence cheap single-sided PCBs.
- Mass production: single-sided PCBs are mostly mass-produced thus saving on production costs and reducing the cost of the PCBs.
- The product design cycle has shortened thus reducing the costs involved in the production.
- Simple designs mean less cost of the single-sided PCBs compared to the more complex ones that cost much more.
- One-stop PCB manufacturer means there are no added costs associated with outsourcing and intermediate links. This reduces the cost of the single-sided PCBs
- All PCBs manufactured pas through vigorous testing and quality standards before sending them to the market.
- Low labor costs also lead to low PCB prices.
- The availability of technical and engineering support ensures that you save costs from the design process to the end of production.
- The various discounts offered by manufactures also reduce the costs of the single-layered PCBs.
Which Industries use Single-Sided PCB?
Single-sided PCBs are used in simple electronics that do not require complex circuits.
Some of its applications include cameras, stereo components, printers, coffee makers, relays, and radio equipment among others.
These include electronics, manufacturing, automotive, medical, aerospace, and robotics industries, amongst others.
Basically, any industry that uses any form of electronics requires a single-sided PCB.
Are there Rules that Guide Single-Sided PCB Manufacturing?
Yes, some rules guide the production and manufacturing of single-sided PCBs. They include:
- Minimizing the number of parts in a design.
- Developing a modular design.
- Using standard components.
- Depend more on multifunctional components.
- Design modules for use in multiple products.
- Design for ease of fabrication.
- Reduce and avoid fasteners.
- Minimize assembly directions.
