In summary, medical PCBs differ significantly from regular PCBs in areas such as reliability, safety, precisión, electromagnetic compatibility, material selection, application domains, traceability, and documentation requirements. These differences necessitate a more stringent and detailed design and manufacturing process for medical PCBs.

Characteristics, Classification and Applications of Breadboards

02/18/2025 en /por

What is a Breadboard?

A breadboard is one of the fundamental components when learning how to build circuits. It contains numerous small holes designed specifically for solderless experiments with electronic circuits. The breadboard is made of plastic blocks, which include a matrix of electrical sockets sized to hold thin connection wires, component leads, or the pins of transistors and integrated circuits (IM). These sockets are connected internally, usually in rows of five. Since various electronic components can be easily inserted and removed without the need for soldering, the breadboard saves circuit assembly time and allows for the reuse of components, making it ideal for assembling, debugging, and training in electronic circuits.

Why is it called a Breadboard?

The name «breadboard» dates back to the era of vacuum tube circuits. At that time, most electronic components were quite large, and people would often fasten them to wooden boards—similar to those used for cutting bread—using screws and nails to make connections. As components shrank over time, the name remained, even though the components themselves became much smaller. The most commonly used breadboards today are typically made of white plastic and are a type of plug-in (solderless) breadboard, designed by Ronald J. Portugal in 1971.
The breadboard serves as a way to validate ideas by creating initial prototypes. If you’re uncertain how a circuit will behave under certain conditions, it’s best to build a prototype for testing. For those unfamiliar with electronic circuits, a breadboard is an excellent starting point. Its main advantage lies in its ability to accommodate both simple and complex circuits. If your circuit can’t fit on the current breadboard, you can easily connect additional boards to handle circuits of various sizes and complexities, such as integrated circuits (IM). If you’re trying to master the operation of a module and need to rewire it multiple times, you certainly wouldn’t want to solder the connections each time. Once an issue is identified, you can disassemble the parts for troubleshooting.

What does a Breadboard look like?

A breadboard typically has a rectangular shape, with varying sizes. It generally consists of two layers: the upper layer is a grid, and it is often covered with double-sided tape (which can be peeled off to fix the breadboard in a specific position). The top layer is composed of rows and columns, with no conductivity between the rows.
The entire board is made from heat-resistant phenolic resin, and metallic strips run along the bottom. Holes are drilled at specific locations on the board, allowing components to make contact with the metallic strips when inserted, ensuring electrical conductivity. Típicamente, every five holes are connected by a metal strip. On both sides of the board, there are two vertical rows of five connected holes, used to supply power to the components on the board.

Characteristics and Advantages of Breadboards

Rapid Prototyping:
Breadboards allow designers to quickly build circuit prototypes for initial testing and validation. This helps to identify and address issues early in the design phase.

Flexibility:
Since soldering is not required, circuits can be easily modified and adjusted. This means designers can iterate multiple times during the prototyping process to optimize the circuit’s performance and functionality.

Rentabilidad:
Compared to custom PCBs, using a breadboard for prototyping is generally more affordable. This makes it an ideal choice for beginners and electronics enthusiasts to experiment with circuits and learn.

Ease of Use:
The design of the breadboard makes inserting electronic components and wires simple and intuitive. Even users with no prior experience can quickly get started.

Types of Breadboards

  • Solderless Breadboard
    A solderless breadboard is a basic, non-permanent platform that does not have soldered power outlets but allows for expansion of individual breadboards. The power supply’s two poles are connected to the slots on either side of the breadboard, and components can be inserted for experimentation (make sure to disconnect the power before inserting components). When more than five components or a set of sockets cannot fit, breadboard cables are used to connect multiple sets of sockets.
    The advantage of a solderless breadboard is its compact size and portability. Sin embargo, its simplicity means it lacks convenient power connections and has a small footprint, making it unsuitable for large-scale circuit experiments. For large-scale experiments, several breadboards need to be fixed to a large wooden board with screws and connected by wires.

Solderless Breadboard

  • Single Breadboard
    A single breadboard uses a main board as the base with dedicated power access terminals, and some breadboards for high-voltage experiments even include ground terminals. This type is more convenient, as the power can be directly connected to the terminals, and components can be inserted for experimentation (again, make sure to disconnect the power before inserting components). If more than five components or a set of sockets cannot fit, breadboard wires are used to connect multiple sets of sockets.
    The advantages of a single breadboard are its small size, portability, and easy power switching. Sin embargo, due to its limited area, it is not suitable for large-scale circuit experiments.

Single Breadboard

  • Composite Breadboard
    A composite breadboard consists of several solderless breadboards fixed to a main board. Típicamente, 2-4 solderless breadboards are fixed onto the main board, with each board’s power lines connected to copper foil on the main board. This type of breadboard is designed to control power for different circuit units, allowing each section to handle varying voltages. The use of composite breadboards is similar to that of single breadboards.
    The advantage of composite breadboards is that they allow for easy power switching, large-scale experiments, mobility, and versatile applications. Sin embargo, they are larger and heavier, making them more suited for laboratory or electronics enthusiast use.

Basic Principles of Breadboard Wiring

When assembling circuits on a breadboard, different individuals may have their own styles. Sin embargo, regardless of style or habits, the following basic principles must be observed:

  1. Minimize Connection Points
    The fewer the connection points, the better. Each additional connection point increases the likelihood of failure. Common issues include poor contact in breadboard holes, loose wires, and internal disconnections.

  2. Avoid «Bridges»
    A «bridge» refers to components or wires that rest on other components or wires. This is a common mistake among beginners and can complicate component replacement later. Additionally, when a failure occurs, tangled wires can easily lead to frustration and loss of confidence.

  3. Ensure Reliability
    Two issues require attention:
    ① Integrated circuits on the breadboard tend to become loose. For components like operational amplifiers, apply pressure to secure them. If the connection is unstable, change the position.
    ② Some component pins on the breadboard may be too thin. Handle them carefully when moving. If they feel insecure, reposition them to ensure a more reliable connection.

Applications of Protoboards

Protoboards have a wide range of applications, primarily in the following areas:

Circuit Prototyping:
Protoboards are ideal tools for circuit prototyping. Designers can quickly assemble circuit prototypes on a protoboard for initial functional validation and debugging. This flexibility makes protoboards especially valuable during the early stages of electronic product development.

Educational Experiments:
In electronics engineering and related disciplines, protoboards are commonly used as experimental tools. Students can build circuits on protoboards to deepen their understanding of electronic principles and enhance their practical skills.

DIY Electronics and Maker Projects:
For electronics DIY enthusiasts and makers, protoboards are indispensable tools. They can use protoboards to create various creative circuits, such as LED strips, small robots, Dispositivos para el hogar inteligente, y más.

Electronics Competitions:
In electronics design competitions, participants are often required to build and debug circuits within a limited time frame. The ease of use and flexibility of protoboards make them the preferred tool in such competitions.

Circuit Repair and Modification:
In some cases, electronic devices may require circuit repairs or modifications. Protoboards can be used to build temporary circuits to replace damaged parts or to expand the functionality of the device.

Protoboards are essential tools in the field of electronics engineering, widely used by engineers, DIY enthusiasts, and makers alike. Through protoboards, they can quickly assemble circuit prototypes, conduct experiments, and bring creative ideas to life.
