Flex-Rigid PCB

Rigid-flex PCBs are created to use in such applications where rigid PCBs are not used. These boards are a combination of rigid and flex PCBs. These boards offered both structures of rigid and flexible PCBs. Mostly rigid flex board comprises substrate created with flexible board and outer parts is created with the use of rigid or internal as well.

Application fields of rigid-flex PCB produced by FS Tech

The use of flexible rigid PCB has become very common in different fields. The use of small size devices enhances the use of these boards. The flex rigid pcb produced by FS Technology can be applied in various fields. In the past service projects, the following fields have received the most praise:

Medical Devices

  • The use of different types of wearable modules has become very common due to the common use of smart devices like watches.
  • Other wearable devices are clothes and rings as well as some medical instruments. The wearable medical devices inform the medical staff to get the details of their patients. Through this process, doctors can monitors the heart beats beatings of patients
  • All these medical devices are created through the use of multilayer rigid-flexible pcb. To make these devices small size for medical instruments flexible and rigid boards are used. This board increases the reliable operation of the devices

Industrial Use

  • There is high stress and temperature environment exists in the industry for these machines used are created through the use of flexible rigid PCB. Its common uses are in circuits that use radio signals for communications transmission of power circuits
  • Through the use of rigid-flex PCB sensors used industries can be of small size. That helps to use them in different projects and enhance their features as well. Since these modules need mostly smaller areas to work on that is only get through use of rigid-flex board
  • The circuits and devices used for power transmissions are created through use of heavy equipment so their movement from one place is another is not easy and increases damage changes of them since are heavyweight.To reduce such problems there must of rigid-flex board used in that devices that will enhance their reliability and long-lasting operation. These boards help machines to work for a larger time interval

Use in Online Business

  • There are different technology are used in online business such as tracking reporting and scanning for shipping
  • To perform these functions there is small size device called PDA is used to complete the process. It also helps to use in difficult conditions where other not easy to use all these happen due to rigid flexible pcb use
At this point, FS Technology’s manufacturing capabilities in rigid-flex boards have been fully reflected. If you think we can make boards that meet your expectations, you can contact us to get your quotation immediately. Although FS Technology mainly focuses on wholesale, it also provides rigid flex pcb prototype services.

Design Guidelines for Rigid-Flex Boards

There are some steps involved in rigid flex pcb design are discussed here


The addition quantity of materiel is added called as a loop. That increases the operating life and the assembly of circuitry make it easy. Use thinner copper materials to get a flexible nature.


There is etching done on the board to avoid the isotropic losses after routing of conductors done to enhance stackup and beddings capabilities of the rigid flex pcb board.

Base Of Board

The base areas of the board is selected then size and weight is decreased. For that purpose reduce the small size holes to about twenty-five mU.


There is the filtering of pads done to make the circuit flexible it can be done by increasing the areas of pads. Button plating is used for making effective solder joints.

Adhesive coated

The adhesive baked coated is used to overcoated the board used to make the board dynamic natures.

Comparison of Rigid Flex PCB with Other Boards

Flexible PCB VS Rigid Flexible PCBs

Flexible PCB has vibration bearing capacity this feature helps to use for vehicles where high vibration is involved. Employed for hard disks. These boards are considered as the solution for wirings used in boards and enhance the repetition in the boards.

You can get the features of rigid PCB and flexible PCB in flex-rigid board. These boards combine the advantages of two different types of PCBs. Their structure helps designers to make three-dimensional design configurations easily. The construction time for these board applications in any project is reduced and makes required products in good design. These boards help to make three dimension designs in fewer prices and solid repetition.

In the following applications, rigid-flex PCBs are superior to flex boards.

  • High Reliable Devices: Since rigid flex PCB can bear the high value of shocks existing on the device were used so it preferred for high reliable applications
  • High-Density components: It is used for high-density applications since has features to get fold into small sizes and offers the fewer space applications
  • Replacement of Rigid Boards: For applications where you need more than five rigid boards can use a rigid-flex board that will be a good and cost-effective solution

Knowledge of rigid flex boards

In this part, FS Tech will introduce some basic knowledge of rigid flex pcb boards. I believe it will be helpful to you whether you are a novice or an expert.

What is a rigid flex PCB

The rigid-flex PCB board is a hybrid board made through a mixture of flexible and rigid PCB boards. For the creation of these boards, there is the use of one or more than one rigid boards combined to flexible boards. These boards are considered the replacement for rigid boards. These boards have features of flexible and rigid boards in one unit. Many rigid-flexible PCBs come in a structure that has multilayers of flexible substrates combined with rigid substrate. Flexible parts of boards designed in curvature structure according to requirements of projects.

Advantages and disadvantages of rigid-flex PCB


  • More Cost-Effective: Although rigid-flex boards are more expensive than rigid or flexible PCBs, they are used in projects to reduce the overall cost of the project because they are a hybrid form of rigid-flex with the characteristics of both types of board.
  • Wider Application Areas: Using a rigid-flex PCB can reduce the use of flex cables and connectors, resulting in a reduction in weight. Therefore, it has the high strength characteristics of rigid PCB and the lightweight characteristics of flexible PCB, which can make it used in different applications.
  • More Flexibility: The combination of rigid and flex structures makes the strong design. The flexible part of boards helps to make design modifications according to the required area and rigid parts give strength to the design. The rigid PCBs are dynamic in nature so can be designed in different types of structures and angles also design can be repeated for other projects.
  • More Convenient Operation: The rigid-flex boards are created by mixing flexible substances to rigid through the substrate of flexible placed in the internal side of rigid boards. The electrical operation of this board is better than other boards. The mechanical and electric connectors are linked at the inner of the board that helping users make reliable boards. 

That is all about the Rigid-Flex PCB all details have been covered about the rigid-flex PCB. Which is best than other boards and comes with features of rigid and flex boards at one place. Due to the advantage of one structure having two materials make it effective and less expensive than other broad that is technically expensive. It is mostly used in industries machines and mobile phones and used in three-dimensional structures and designs. Flexible PCB has a high level of resistance from hazardous chemicals as well ultraviolet light and oils. In computers and mobile phones mothers’ boards are created through the use of this board all components of circuits are assembled on the board in an accurate and simple way to make fine circuits.
