Printed Circuit Board (PCB)

What is a Printed Circuit Board (PCB)?

A printed circuit board is the foundational architecture block used as the basis for most electronic devices: A wiring area for equipment, assembly, and plug-in components. Circuit boards are usually made of fiberglass, epoxy or other composite materials. The printed circuit board (PCB) is the main component of most modern electronic devices. A single-layer board in a garage door drive or a garage door drives up to a six-layer board. And the 60-layer, high-speed, very dense smartwatch on the PCB used in the supercomputer. Servers and circuit boards are the basis for installing all other electronic components Semiconductors, connectors, resistors, diodes, capacitors, and radio equipment are assembled and “communicated” with each other through printed circuit boards.

Why Are Printed Circuit Boards Used?

Compared with traditional wired circuits, printed circuit boards have many advantages. Its compact and lightweight designs are suitable for many modern devices. Their reliability and easy maintenance enable them to be integrated into complex systems. In addition, their low manufacturing costs make them a very profitable option. Victory PCB is providing printing circuit boards of these characteristics. These characteristics are some of the reasons why PCBs are used in all industries, including the following markets:


Medical electronic products have benefited a lot from the introduction of printed circuit boards. Electronic components in computers, imaging systems, MRI machines, and radiation equipment are constantly evolving using the electronic functions of circuit boards. The thinner and smaller flexible and rigid circuit boards make the circuit boards more compact and Lightweight medical devices. So, like hearing aids, pacemakers, implantable devices, and ultra-small cameras for minimally invasive interventions. Rigid-flex circuit boards are particularly suitable for shrinking complex medical equipment. They eliminate the need for flex cables and connectors that take up valuable space in more intricate systems.


Rigid, flexible and rigid-flex printed circuit boards are commonly used in instrument panels, instrument panels, flight control, flight control and safety systems in the aerospace industry. The continuous advancement of aerospace technology makes smaller and more complex PCBs used in aircraft, satellites, drones and other aerospace electronic equipment. Since there are no connectors, flexible and rigid-flexible circuits provide excellent durability and survivability. It makes them suitable and beneficial for use in environments with strong vibrations. The lightweight structure reduces the overall weight of the equipment, thereby reducing fuel consumption.


In the military field, printed circuit boards (PCB) are often used in equipment subjected to substantial impacts and vibration applications: military vehicles, rugged computers, advanced weapons, and electronic systems. The development of military technology requires more and more equipment to meet the changing customers. For this, you have to adopt advanced computerized technology. This requires the electrical and mechanical properties and bending stiffness of the flexible gasket. These types of electronic enclosures can withstand thousands of pounds of force without interruption.

Industrial and Commercial:

The use of printed circuit boards in industrial and commercial electronic products has completely changed everything from manufacturing to supply chain management, improving information, automation and efficiency. Overall, they are reliable equipment management tools in increasingly automated systems that can increase productivity and reduce labor costs. Flexible and rigid FPCB allows manufacturers to use smaller and lighter products Increased functionality and higher reliability.

Types Of Printed Circuit Boards

Although all printed circuit boards PCBs have the same essential purpose, they have various designs and configurations to meet the needs of multiple applications. Some of the different types available on the market are:

 rigid single-sided rigid 

double-sided rigid 

multi-layer Single 

layer flexible circuit 

Bilateral flexible circuit

Multi-layer flexible circuit 

Rigid-flex High frequency 

Aluminum housing

The three most common types are:

  1. Rigid PCBs

Rigid circuit boards are made of challenging fiberglass substrates, making them practical and inexpensive but still inflexible. Compared with more flexible similar products, they are easier and cheaper to manufacture. But its versatility is much worse, and it is difficult to adapt to unusual geometric shapes or small areas.

  1. Flexible PCBs

Flexible printed circuit board (PCB) has a relatively good bending and folding ability to adapt to limited space and irregular shapes. In addition, products do not have to meet the limitations of circuit boards because of their strong adaptability. Compared with rigid circuit boards, they are more heat-resistant.

  1. Rigid-Flex PCBs

Rigid circuit boards combine the most attractive characteristics of wooden and flexible circuit boards. Unlike the other two types of PCBs, these printed circuit boards (PCB) contain all of these electronic connections hidden in the council, reducing the weight and overall size of the board. When ultra-light packaging is an essential requirement, they are a good choice. In addition, they are more durable and reliable while maintaining greater strength and flexibility.
