Manufacturers ideally use them in moving and shakable devicesThese boards are beneficial to use in limited space applications.
Their components can’t move even in harsh application environments.They are more expensive than rigid boards.
Furthermore, their designs also allow for easy maintenance and repair.Their popular applications are medical devices, space, automotive appliances, and many more.
They can low electronic noise.They are helpful to create thin, lightweight, and long-lasting devices.

What is a Cable Assembly?

In fact, a cable assembly is a special group of cables. Further, designers arrange these cables inside only a single unit for some specific purposes.

If we compare these cable assemblies with rigid-flex circuit boards, we find them costly. But they help to make installation much easier and quicker.

These assemblies are extremely useful to use in mass production.

Because they can save your precious time during the assembly of the overall machine.

Moreover, the cable assembly manufacturers are increasingly using them in the automobile industry.

We are sure that you have got all the essential information about Rigid-Flex PCB vs. Rigid PCB and Cable Assembly.

So, let’s move to know about the 4 reasons for using Rigid-flex boards over Rigid PCB boards and cable assemblies.

Why Flex Circuits are Best in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly?

Actually, there are several reasons for electronic designers to use Rigid-flex circuit boards over Rigid boards.

We have brought 4 top reasons for you. these are:

  1. Rigid-flex circuits can provide great versatility in electronic devices.
  2. They can ideally fit where weight and space are very small.
  3. These boards are generally ideal to use in medical devices.
  4. Further, they are perfect for mobile consumer electronics and sensors, etc.

Products Which Ideally Use Flex Circuits in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly

As we have already explained to you that flexible circuits are highly advantageous to use in modern smart electronic appliances.

Moreover, they are also perfect to use in the following products which need,

  • Smart, lightweight, and durable solutions;
  • Three-dimensional package geometry;
  • Best wiring solutions where rigid boards can never fit;
  • Vibration and extra shock resistance;
  • Reduced versions of already existing technologies.

In Which Applications can Rigid-Flex PCBs Excel?

It is a fact that rigid-flex PCBs can reach a comparatively higher cost in comparison to rigid boards.

But their durability, reduction in weight, compact sizes, reliability, and several other benefits make them an ideal choice.

Furthermore, all these useful features highly rank them in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly.

Today electronic engineers are greatly relying on them because these boards can outperform any other good electronic technique.

They have indescribable benefits, so electronic designers always prefer to use them.

Moreover, they have the best capability to give ideal advantages not only for rigid but also for flex PCB needs.

Here we have tried to put all those applications where rigid-flex PCB circuit boards excel.

These extremely useful applications are:

Higher-Density Applications:

In fact, it sometimes becomes impossible to lodge cable assemblies and connectors into just a small housing.

Actually, all these connectors and cables are essential need in such applications. Moreover, they are part and parcel of them.

Flexible PCB

So, rigid-flex circuits have the ability to fold all those necessary elements into very small profiles.

These circuit boards are space savings and best to use in all the above circumstances.

Highly Reliable Applications:

The Rigid-flex PCB boards are ideal for those applications which have to face extreme shocks or repeated vibration environments.

Because in such conditions, cable assemblies and rigid boards fail.

So, electronic engineers highly rely on rigid-flex boards in those applications where shock and vibration occur again and again.

Hence, this is the reason, why electronic designers prefer Rigid-flex boards in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly.

Five or More Rigid PCB Circuit Boards:

The engineers also make use of these circuits when they have to use five or more rigid boards.

Moreover, cables also exist in order to connect these rigid boards. All of these factors make electronic solutions more complex.

In such conditions, rigid-flex boards will be cost-effective and an optimal choice.

How Rigid-Flex PCBs Provide Highly Effective Cable-free Electronic Designs?

the ability to eliminate

  • Connectors;
  • Flexible cables;
  • Several discrete wiring.

As you know that, the use of PCB boards is essential to create any simple to complex electronic device.

Furthermore, these boards are now an integral part of the construction of any electronic gadget.

They also make the design simple by reducing or totally eliminating the flexible cables and connectors.

As well as, these boards also have the capability to provide electronic designers with an improved and reliable solution.

Rigid-Flex PCBs Deal for High-Temperature Applications in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly

In this modern age of electronic technology, electronic manufacturers are greatly preferring to use rigid-flex PCB boards.

They are not only using these boards for manufacturing and consumer applications but also in industrial devices.

Because these circuits are highly chemical resistant.

Moreover, these rigid-flex boards can also withstand exposure to high heat, UV exposure, and radiation.

In fact, PCB designers use the best quality polymer or polyimide (polyimide is almost similar to polymer).

Hence, these circuits can dissipate the extra heat comparatively better than that of rigid boards.

Their material is much better in comparison to rigid PCB boards.

Furthermore, the best variation of polymer also can encounter extreme conditions without leaving negative impacts.

For example, rigid-flex PCBs are ideal to use in industrial sensor technologies.

So, all these best features make rigid-flex circuits better in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly.

Why Choose Ideal Material for Rigid-Flex Circuits in Rigid-Flex PCB vs. Rigid PCB and Cable Assembly?

Actually, rigid-flex PCB boards work by using the 2 most common and useful materials. These materials are:

  • Copper
  • Polyimide adhesive.


Copper is actually a global conductor that manufacturers use in almost all types of circuits.

You can never fabricate your PCB circuit boards without using copper. It has the ability to transmit all signals without losing electricity.

Further, you need only a very small amount of copper to create a rigid-flex PCB and several other types of circuits.

Polyimide adhesive:

Basically, polyimide adhesive is the second global material. This is very essential to use in rigid-flex circuits.

Because it joins the rigid and flexible layers together in a rigid-flex PCB circuit board.

Moreover, electronic manufacturers should do some practice before using polyimide adhesive in the rigid-flex board.

Actually, it is essential to become an expert to use polyimide adhesive. Otherwise, you can’t construct an ideal working rigid-flex PCB.

A very popular example of their application is smartphones. Nowadays you can see that modernistic smartphones are more functional and extremely thin.

All this has become possible only because of the latest rigid-flex technology.

Furthermore, all modern computer electronics are rapidly using rigid-flex boards.

You can see that all the latest electronic gadgets have become smaller like never before.

All this progress has happened just because of rigid-flex circuits.


We have actually tried to sum up all the beneficial uses of rigid-flex boards in modern electronics.

Their applications are very extensive. As well as their implementation is growing increasingly beyond your imaginations. They are greatly effective to use in,

  • Military;
  • Medical;
