Expensive and complex discrete interconnect cables can reduce design reliability, increase design cost and overall design size. In practice, discrete interconnect cables are a disadvantageous design. For electronic product sellers it goes against the trend of miniaturization of electronic products, and for PCBA manufacturers, it is an unreliable design. For project leaders, discrete interconnect cables are not only more expensive but also more complex. Fortunately, FS Technology's rigid-flex PCBA will be the perfect substitute.
The advantages of FS technology manufacturing rigid-flex PCB
FS Technology specializes in the production of this rigid-flex PCBA, which is designed for flexibility and reliability to provide a cost-effective and convenient solution for your electronic projects. Discrete interconnects have different conductor orientations, whereas flex PCBAs keep all conductors in a specific orientation fixed to each other. Accurate modeling and more predictable design of PCBA traces with reliability and flexibility.
In addition, in the part of the FPC, FS Technology provides gold finger contacts, allowing the edge of the FPC to be used as the male part of the connector and can be adapted to high-density designs. Today, in order to meet the needs of electronic product users, this rigid-flex PCB replaces almost all traditional discrete interconnect solutions and enables a highly modular design.
The benefits of rigid-flex PCBA for electronic projects
FS Technology's flexible PCBA not only provides an effective method for designing and producing interconnect solutions, but also enhances the accommodation of the circuit board and becomes the focus of the solution. The use of rigid-flex PCB can make the volume of electronic products smaller, which is unmatched by traditional circuit boards. Instead of mounting components to rigid PCBs, you can mount boards produced by FS Technologies on all flexible solutions. In addition to the above advantages, the rigid part of the rigid-flex PCBA can act as a stiffener, providing your electronic project with a reliability that a flexible PCB cannot. Most of the wearable devices, digital cameras, and medical devices used today use rigid-flex PCBs instead of just FPC or rigid PCBAs.
FS Technology believes that flexible rigid PCB is the best of all flexibility solutions. Features a flex-rigid design with built-in interconnect between the two boards. Using rigid-flex PCBAs manufactured by FS Technology in different solutions, designers can accommodate 3D solutions in one assembly step. The use of rigid-flex PCBA instead of traditional circuit boards or discrete connections can shorten the assembly time of mechanical assembly. As the demand for PCBs by electronic product sellers increases, it is proved that rigid-flex PCBs are a catalyst for any electronic solution.
Although rigid-flex PCBs are better than traditional PCBs, they are very similar in the design process. As a turnkey PCB manufacturer, special attention to mechanical quality is required when creating flexible parts. When creating a 2D layout of a flexible PCB design, it is best to use a 3D modeling software to create a mockup of the flexible design, or to create a paper mockup of the design. This method is convenient for testing whether the design meets the mechanical specifications of the flexible substrate. In addition to that, the PCB you design does not need to have a bend radius smaller than what a flex PCB allows.
FS Technology recommends that you pay attention to the following points when designing rigid-flex PCBs:
- Increase board flexibility with staggered traces on each layer of the flex circuit.
- Conductors must not be routed perpendicular to the bend radius
- Termination areas should be reinforced with stiffeners
- Use a cross-hatched pattern instead of a solid plane
- Vias should be kept away from bend areas
Communication with turnkey rigid-flex PCB assembly company
Before sending manufacturing files of rigid-flex PCB to FS Technology, please consider the plan's executable in advance, such as the flex board is bendable and has the highest density when nested. If a specific dimension can be achieved by bending the PCB, usually we do not bend it in the initial design, but in the assembly step. Finally, I hope you know that the few rigid-flex PCBAs you design are more expensive than flexible PCBs. Try to use a smaller number of layers for your project needs, it will be more profitable for the electronics you sell. Flexible rigid solutions should only be considered if your design has very large layer count requirements.
Finally, filling a flex PCB is very similar to filling a rigid PCB. When doing flexible PCB assembly, consider the following tips:
- Bake the flex PCBs for an hour, then fill them to remove any absorbed moisture.
- Fix the flex PCB to a hard surface to provide dimensional stability when soldered to the device.
- When hand-soldering the device to the flex PCB, skip the solder-intensive fixtures to avoid overheating parts of the flex PCB.
In conclusion, rigid-flex PCBs can greatly reduce the cost and complexity of your electronics manufacturing process. Rigid-flex PCBAs are an excellent alternative to traditional discrete routing solutions, offering the repeatability and reliability of PCBs in a flexible form factor. Additionally, rigid-flex PCBAs offer the opportunity to create highly complex 3D designs while maintaining low assembly costs, high levels of repeatability and reliability. In short, rigid-flex boards will allow you to handle designs that are too costly, complex or simply impossible to manufacture. Take your designs to the next level with rigid-flex boards.
