If you are considering building a device, you should know that the critical component it requires will be a printed circuit board. The type of board you will use in it will depend upon the use of the gadget.

There are a lot of circuitry types which are compatible with a device, as PCB has a wide range of functions. However, the final designs that you will use are going to depend on only one question: What is adequate for your device? It can ultimately prove to be an ideal system for you.

The most common type of circuit boards is of Flexible and Flex-Rigid PCB. If you take a closer look at it, you will notice that it has a primary application. To find out further about them, we will explore both the Flexible and Flex-Rigid PCB a bit more.


Flexible Printed Circuit Boards:

A PCB can be flexible and twist and turn like a rubber. They are obtainable in both single and double board configurations. They are mainly built using epoxy resin and polyimide. The advantage which they offer is that they can form any shape as per requirement.

The cost is slightly more since the flexible PCB requires expensive material to build. On the other hand, we can lower the price because a piece of a flexible board can do the same work as multiple rigid boards.

Flexible board composes of copper and Kapton, where the goal is to offer flexibility and temperature resistance. It gives the manufacturers the freedom to design the product according to their needs, without being dictated by the design of the circuit board. Furthermore, the material used in PCB construction makes it water and shock resistant.

The flexibility helps in weight reduction, giving extra durability and compactness to the design of the contraption.

The Pros and Cons of a Flexible PCB are:

  • They are more reliable than rigid boards
  • Cost of production is high.
  • They can tolerate quite a lot of pressure and temperature.
  • Gives the freedom to accommodate different design features.
  • It can be put to use for outdoor activities.

Flex-Rigid PCB:

A Flex-rigid Printed Circuit Board is an amalgamation of both a rigid and flexible circuitry. Thus their shape is more like a traditional board, even though they multi-layers of different designs. It means that a flex-rigid board has the combined advantages of both types of boards.

A board like this will proves useful as you can connect it to any number of devices that have a varying degree of applications. The wiring on these boards will be more accessible, giving a constructor more free hand to build a product.

It means that the designs will be more streamlined and effective. There are multiple layers of the board so you can choose which segment should be of what type. The outer layer is exposed to the elements so it will be possible to provide a covering for PCBs. Usually, a conductor is used to assert more pressure; a flexible layer is provided to punch in holes for additional connections.


The Pros and Cons of Flex-rigid PCB are:

  • There is no need for ‘Soldering,’ as the product is quite durable.
  • The cost of production is lower than a flexible Board since it makes only a small part of Flex-rigid board.
  • They are more resistant to changes in the weather and degradation over time.
  • They require a minimal maintenances and quite reliable.
  • Since, they are more temperature resistant, and changes in conditions; they will have fewer and fewer connecting parts.

Some of the appliances where Flexible and Flex-rigid PCB are in use:

  • Medical Appliances:

Flex Printed Circuit Boards are essential for medical devices. Since doctors and para-medical staff have to deal with patients all the time. The equipment has to be nearby at all times. It means that they should not only be portable but also stead and reliable in the harshest of conditions. Probes used to check the inside of a person has to be flexible to meet with the individual requirements.

A heart monitor and fitness tracker have flex-rigid chips in them. It provides durability and provides some backup to stop the product from being destroyed. The doctors rely more on products which they can carry with them to perform on the spot checkup. These instruments need to be solidly built. A flex-rigid circuit board can offer these solutions.

  • Smartphones:

A smartphone has become so much dynamic that it needs a lot of flexibility. There have been launches of foldable phones which require a flexible circuit. A single layered flexible printed circuit board will be able to provide all the significant advantage for a cellular device. A mobile phone needs to be portable, light-weight, and compact.

A mobile phone is carried around everywhere regardless of the conditions. So a typical circuit board will cease to function. A phone whose screen can bend requires a great deal of engineering. A fixed circuit board is unable to fulfill the requirements. Moreover, a flexible circuit board is effective against water and dust.

  • Computer:

A computer system be it in the form of a laptop, desktop, or a tablet requires extensive circuitry. A hard drive spins at incredible speeds producing a lot of heat. It operates for an extended period, which means that it needs to withstand a massive amount of stress.


A flexible circuit and PicoBlade 1.25mm Connectors enable a computer to perform well under such adverse conditions. A flexible circuit board also exist in related technologies such as printers, scanners, keyboards, and mouse.


A Printed Circuit Board has become a core element of every piece of technology. Since their inception, initiators of industries have been able to come up with new products which have proven to be beneficial. The PCB has helped in producing cost-effective and highly efficient machines.


Flexible and Flex-Rigid Printed Circuit boards are increasingly in use in new devices. They are crucial for machinery since the development is taking place at such a rapid speed, so more modern designs of circuit boards have primarily grown in demand.
