Everything About PCB You Should Know

Printed Circuit Boards or PCBs are critical components in every modern electronic device. PCBs are found in many gadgets, including computers, calculators, toys, smartphones, medical equipment, automobiles, and many others. 

They are used in these electronic devices because they come with numerous benefits. For example, they are cost-effective and help reduce the size of the device. Below is a summary of all you need to know about PCBs. 

What is PCB?

A Printed Circuit Board or PCB has become a known element in the electronic industry. This is because it is the heart of modern electronics. 

PCB is a board made from layers of metal interconnects, electric conductors, insulators, and other elements connected using copper tracks fixed to the board’s surface. 

Moreover, the circuit board offers mechanical support and connects electronically electric elements using conductive pathways. PCBs are used in various devices because of their ease of use and safety from electrical risks. 

Although printed circuit boards are mainly used in electronics, they are found in different sectors of our lives. This is because they are the foundation of most electronic gadgets. 

Since there are simple electrical devices and complex ones, there are different types of PCBs. There are single-sided PCBs for simple devices, multilayer PCBs for complex devices, and others, including flex PCBs, Rigid PCBs, and Rigid-Flex.

Common used PCB types

1. Rigid PCB

Rigid Printed Circuit Boards are solid, inflexible PCBs that can be single-sided, double-sided, or multilayer. Thus, it is a circuit board that cannot be forced out of shape or cannot be bent. 

Once a Rigid Printed Circuit board is manufactured, it cannot be folded or modified into another shape. Most of the PCBs you see in devices such as computer motherboards or smartphones are Rigid PCBs. 

However, PCBs are cheaper than flexible PCBs. They are traditional forms of printed circuit boards and are used in many common devices. 

Benefits of Rigid PCBs

  • Rigid Printed Circuit Boards are cheaper compared to Flex Printed Circuit Boards. 
  • Since they cannot be folded, they are very durable. 
  • Rigid PCBs are of high quality and density. 
  • Since they are affordable, they are widely used in various electronic devices. 

Uses of Rigid PCBs

Rigid PCBs are very common because they offer the enhanced density and reduce the size and weight of the circuit board. Hence, many electronic manufacturers use the boards in various gadgets. 

Some of the devices where you can find Rigid PCBs include:

  • Computers and Laptops
  • Medical equipment
  • Signal transmission and mobile phone repeaters. 
  • Automotive
  • Aerospace

2. Flex PCBs

Flex PCBs, Flexible PCBs, or Flexible Printed Circuit Boards are circuit boards that can be folded. They are not as solid as rigid PCBs. They are made of flexible material that is easy to bend, handle, and transport without damage. 

Today, flexible PCBs are found in various devices. Moreover, you can find single-sided flex PCBs, double-sided flex PCBs, and multilayer flex PCBs. 

Benefits of Flex PCBs

Even though most devices use rigid PCBs, flex printed circuit boards offer many benefits. Some of the advantages of flexible PCBs include:

  • Reduced in size and weight
  • Foldable and bendable
  • Easy transportation
  • Increased freedom when designing
  • Space-saving

Uses of Flex PCBs

Due to their flexibility, small size, and lightweight, many electronic manufacturers use the boards in various electronic gadgets. Some of the uses of Flex PCBs include:

  • Thin, lightweight products
  • Mobile phone
  • Laptops
  • 3D electronic products
  • Sensor
  • And in the oil and gas industries. 

3. Rigid-Flex PCBs

Rigid-Flex PCB is a mixture of flex PCB and Rigid PCB. Thus, the board consists of rigid and flexible substrates laminated to form a single circuit board. There are double-sided and multilayer rigid-flex PCBs. 

Unlike the other PCBs, Rigid-Flex Printed Circuit Boards are a bit complex to design and make. Most of them are manufactured in 3D, and the manufacturing process involves several steps. 

Benefits of Rigid-Flex Printed Circuit Boards

  • Reduced weight and space
  • The advantage for anyone looking for a flexible or rigid PCB
  • It works in eliminating a lot of solder joints and wiring
  • Better electrical connection consistency
  • Great for 3D design
  • Cost-effective when it comes to transportation and handling
  • Less number of electronic components
  • Offers complete testing before installation

Uses of Rigid-Flex Printed Circuit Board

Rigid-Flex Printed Circuit Boards offer numerous benefits to board manufacturers. They are flexible, reliable, lightweight, and save a lot of space. Thus, many electronic manufacturers use circuit boards in many electronic gadgets. 

Some of the uses of rigid-flex PCBs include:

  • Aerospace
  • Military weapon
  • Mobile phones and tablets
  • Digital Camera
  • Laptop and computer
  • Medical gadgets
  • Automobile
  • Pacemaker
  • Testing and measurement equipment

Tips for choosing the right PCB

PCB is a vital element in any electronic device. Therefore, there should be no mistakes when choosing. Choosing a printed circuit board is not as complicated as it looks. Nevertheless, it would help if you looked into various factors to pick the right one. 

Here are some of the tips to consider when choosing a PCB:

1. Design, type, and quality of the PCB 

Making a PCB is not a simple task because you need to focus on the type, design, and quality. For example, if the board is not well designed, it can cause issues in the assembly process. Meanwhile, the manufacturing steps are also important, such as silkscreen, pressure, CNC drilling process, and so on.

2. Pick the best assembly method

There are various assembly methods when it comes to PCB manufacturing. Since assembly is one of the most important methods, you need to choose carefully. 

3. Check the costs

Another important tip that will help you choose the right PCB is the cost. It is essential to check your costs while selecting a printed circuit board. However, do not just go for the cheapest service. 

Final Word

Printed Circuit boards have become essential elements in modern electronic devices. Therefore, when selecting a PCB for your business, you need to make the right decision because competition is real. 

Happily, with the above information, you can select the right PCB for your business. Make sure you focus on the printed circuit board’s type, design, and quality.
