Introduction of industrial PCB types based on rigid and flexible


Industrial PCB types based on rigid and flexible:

In addition to layers, the PCB can also be divided into different parts based on stiffness. According to rigidity, PCB can be divided into three types.

Rigid PCB:

A rigid PCB is a PCB that is rigid in nature.

The substrate of these PCBs is not flexible. Rigid PCBs are widely used in industrial applications.

Due to its strong substrate, it is durable and easy to repair.

Rigid PCBs usually handle very complex designs. It is easy to implement and organize signal paths on a rigid PCB.

The compact size of the rigid PCB ensures that various complex designs can be made around it for one application.

As with rigid PCBs, all components are fixed with flux.

The whole process is completed in such a way that even if you use them in a harsh application environment, all the components on the PCB will not move.

Flexible printed circuit board:

A flexible circuit board is a circuit board similar to a rigid circuit board, and its necessary components are placed on a flexible substrate instead of a rigid substrate.

The plate is manufactured in such a way that it can be bent into any desired shape during application.

Flexible PCBs are inherently flexible.

You can easily fold it. The base material of flex-PCB is flexible.

This type of PCB also has single-layer, double-layer and multi-layer formats.

Because this type of PCB is light and flexible, it is widely used in industrial applications.

There are different types of flexible circuit boards according to the number of layers and configurations.

This type of PCB also has single-layer, double-layer and multi-layer forms.

PCB with rigid and flexible combination:

Rigid-flex PCB is a hybrid PCB of rigid PCB and flexible PCB.

Many rigid printed circuit boards are used for rigid-flexible printed circuit boards. The rigid part of the rigid-flex board is usually used to place the connector and install the chassis.

This rigid-flex design helps increase the capacity of any PCB.

The biggest advantage of rigid-flex PCB design is that it does not need to make any compromises in equipment or application design, so any type of design can be carried out in consideration of user convenience.

This type of circuit is mainly used to implement complex circuits, so it is used where the circuit space is the smallest but the circuit complexity is the largest.

Because of its rigidity and flexibility, it is one of the most commonly used circuits in industrial applications.


The full name of HDI is High Definition Internet.

This type of PCB is used for devices or applications that require higher performance than general Flex PCBs.

This type of layout is especially helpful in creating a perfect layout. It uses much thinner layers than general flexible PCBs, which helps to reduce the overall size and efficiently use energy.

Choose this type of PCB to create a high-performance PCB. These types of PCBs can be used in industrial applications as required.

High frequency PCB:

This type of PCB operates at high frequencies from 500MHz to 2GHz. This type of PCB has been used for critical frequency applications.

There are other types of PCB, such as high-speed PCB, LED PCB, RF PCB, METALCORE PCB, THICK COPPER PCB, GOLD FINGER PCB, CERAMIC PCB, etc.
