Basic Components and Structure
A breadboard consists of a grid of holes arranged in rows and columns.
The holes are connected internally in a pattern that allows electronic components to be inserted and interconnected without soldering.
These typically have two main areas: the terminal strips, where most components are placed, and the bus strips, which provide power and ground connections.
This structure makes them flexible and easy to use for various circuit designs.
PCBs, on the other hand, are made of a non-conductive substrate, usually fibreglass, with copper traces etched onto the surface to create pathways for electrical signals.
Components are soldered onto the PCB, creating permanent connections. The structure of a PCB includes layers for different functions, such as power, ground, and signal routing.
PCBs come in various sizes and configurations, including single-layer, double-layer, and multi-layer boards, allowing for more complex and compact designs.

Adjustments can be made easily, facilitating iterative design processes.
Compared to the time-consuming process of designing and manufacturing a PCB, these boards offer immediate setup and flexibility, ideal for early-stage development and troubleshooting.
University students can rapidly assemble and adjust sensor circuits on breadboards, enabling immediate hands-on learning and feedback.
Disadvantages of Breadboards:
Limited Durability
They can suffer from wear and tear over time.
Repeated insertion and removal of components can loosen the connections, leading to unreliable performance.
Unlike the solid connections of a PCB, these board connections may degrade, especially in frequently used areas.
A hobbyist may encounter intermittent faults in complex home automation projects due to loose connections on a breadboard over time.
Higher Risk of Loose Connections
Loose wires and components are common issues with breadboards, causing intermittent connections.
These unstable connections can lead to circuit malfunctions, making them less reliable for long-term use.
Troubleshooting these issues can be time-consuming and may affect the accuracy of your experiments.

They also excel in handling complex and high-density circuit designs.
They can support multiple layers and intricate routing, making them ideal for advanced electronics.
High-frequency and high-power circuits benefit from the precise and stable connections that they provide, which are essential for reliable operation.
For instance, multi-layer versions they are commonly used in sophisticated devices like smartphones and computers.
Disadvantages of PCBs
Higher Initial Cost
The upfront costs of designing and manufacturing these products are higher compared to breadboards.
This includes the expenses for custom design, production, and assembly. For one-off projects or small runs, these costs can be significant.
Longer Development Time
Creating a PCB involves several steps, including design, fabrication, and assembly, which can be time-consuming.
Unlike breadboards, which can be set up immediately, these require careful planning and preparation.
This extended timeline can impact project schedules and deadlines.
Less Flexibility for Changes
Once a PCB is manufactured, making changes can be difficult and costly.
Adjustments often require redesigning and producing a new board, unlike breadboards where modifications can be done easily and quickly.
This lack of flexibility necessitates careful design and consideration before committing to a PCB.
Discovering a design flaw in a PCB during final product development can lead to costly and time-consuming rework, unlike the flexibility of breadboards.
Cost Comparison
