Industrial Applications

In the industrial manufacturing sector, there are some challenging issues. The circuits and devices used for power transmissions are created through the use of heavy equipment, so their movement from one place is another is not easy and increases damage changes of them since it is heavyweight. To address this, industrial PCB with both rigid and flexible characteristics are the ideal solution.

The combination of rigidity and flexibility can ultimately solve the overall weight problem of equipment. The rigid part is easier to manufacture in multilayer structures, achieving high-density component layouts to meet the high-performance requirements of the equipment. The flexible part can serve as a buffer and shock absorber to reduce vibrations during the operation of heavy machinery.

Use in Online Business

Online business is a branch of 5G communications. With the rapid development of 5G technology and the repeated outbreaks of the new crown epidemic, the demand for online business has grown exponentially. Online businesses in this environment need to incorporate a variety of technologies, such as tracking reporting and scanning for shipping. To perform these functions, there is a small size device called PDA is used to complete the process. It also helps to use in difficult conditions where others are not easy to use, all these happen due to rigid flexible PCB use.

Rigid Flex PCB Buying Guide​

Existence is reasonable. Based on different considerations, all manufacturers have a chance to be selected, even if their prices are higher. For you, with a clear goal, choosing a rigid flex circuit board manufacturer that better suits your needs will play a decisive role in the progress of your electronic project. Most of the time, we will consider the manufacturer’s PCB manufacturing capabilities, turnaround time, service fees, etc. Here, FS Technology provides an idea for PCB selection, that is, whether it is really necessary to use a more expensive rigid-flex PCB.

Whether rigid flex PCB design service is required

There are two categories of customers for electronic assembly projects. One category is customers who have clear requirements and have drawn PCB circuit diagrams, they usually send documents directly and inform the required quantity to get a quick rigid-flex PCB quotation. Another type of customer just has a concept or idea and seeks the help of a turnkey PCB assembly company.

Design is the first step in the entire rigid-flex PCB turnkey assembly service, and customers need to judge whether they need to design or modify the service. For electronics companies with design engineers, it is obviously not a wise choice to choose a turnkey assembly company for design services. In past cases, FS Technology is more of a helper to help customers complete rigid-flexible projects. Of course, our designer team can also help customers complete design projects independently. 

Discuss rigid-flex PCBA design

Here we provide simple rigid flex PCB design guidelines for your reference.

  • Looping

An additional quantity of material is added called a loop. That increases the operating life and the assembly of circuitry makes it easy. Use thinner copper materials to get a flexible nature.

  • Etching

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

  • Base Of Board

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

  • Filleting

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 coat is used to overcoat the board used to make the board dynamic natures.

Is it necessary to purchase a rigid-flex PCB?​

The rigid-flex PCB board is a hybrid board created through a combination of flexible and rigid PCB materials. It involves using one or more rigid boards combined with flexible boards to form a single unit. Rigid-flex PCB are considered a viable alternative to traditional rigid PCB, as they offer the benefits of both flexible and rigid boards in one package. The flexible portions of the boards are designed to accommodate project-specific curvatures. Despite the numerous advantages of rigid-flexible circuit boards, the cost of manufacturing has discouraged some electronic manufacturers from choosing this type of PCB. However, the decision to opt for a rigid-flexible PCB should be carefully considered based on the specific requirements of the project and the benefits it can bring.

Reasons for Buying Chinese Rigid and Rigid PCBs

Reasons to Get a Rigid Flex PCB Quote

  • Cost-Effectiveness: Although the initial cost of rigid-flex PCB may be higher, they eliminate the need for additional cables and connectors, simplifying the assembly process and reducing material costs.
  • Wider Application AreasBy avoiding the use of connectors, the overall weight and dimensions of the equipment are significantly reduced, resulting in greater versatility. This meets the requirements for internal space in small devices and provides benefits for wearable electronics.
  • Enhanced Flexibility: The combination of rigidity and flexibility provides a more versatile design platform. It allows bending to adapt to specific areas while offering sufficient strength, reducing limitations for designers.
  • Convenient Operation: Rigid-flex boards are designed by incorporating flexible substrates within rigid boards, creating strong electrical connections. This configuration enables better electrical performance and enhanced mechanical reliability. The inner placement of electrical connectors enhances user convenience, ensuring the creation of reliable and efficient boards.

Flexible PCB VS Rigid Flexible PCB

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.

Firstly, the manufacturer separately produces the rigid circuit and the flexible circuit through the design file, and then chooses different ways to connect the two parts according to the needs of the customer, such as using a flexible circuit connector or a spring connector; or directly weld the two parts; or design a socket on the rigid part during design.

Rigid-flex PCB refers to a type of circuit that uses a flexible circuit to connect multiple rigid PCBs. The semi-flexible PCB uses the traditional manufacturing process to produce FR-4 PCB, and then uses deep milling technology to thin the area that needs to be bent, so that it has a certain degree of flexibility, and is essentially a rigid PCB.

In addition to FS Technology, you have other choices: If your project does not have a profit advantage, the rigid-flex PCB supplier quoted online is the best choice; if you pay attention to quality, you can choose a supplier specializing in the production of flexible circuits; if you want to gain an advantage between the two, FS Technology will help you!
