Rigid-Flex PCB

Rigid-Flex PCB

A rigid-flex PCB is a type of circuit board that combines rigid and flexible sections. It allows the board to bend, twist, or fold while providing stability and support. It saves space, improves reliability, enhances signal integrity, and offers design flexibility. They are used in compact electronic devices and industries like aerospace and medical devices. Manufacturing rigid-flex PCBs requires specialized techniques..

Benefits of Rigid Flexible PCB

  • Space-saving

    Rigid-flex PCBs eliminate the need for connectors and extra wiring, allowing for a compact design and efficient use of space within electronic devices.

  • Increased reliability

    The absence of connectors and interconnects reduces the risk of loose connections, short circuits, and mechanical failures, resulting in improved overall reliability.

  • Enhanced durability

    Rigid-flex PCBs are designed to withstand repeated flexing, bending, and vibration, making them suitable for applications that require durability and resistance to harsh environments.

  • Improved signal integrity

    The elimination of connectors and shorter signal paths in rigid-flex PCBs minimizes signal loss and electromagnetic interference (EMI), leading to improved signal quality and integrity.

  • Simplified assembly

    Rigid-flex PCBs streamline the assembly process by reducing the number of components and interconnects, resulting in faster and more efficient manufacturing.

  • Cost-effectiveness

    Despite the initial investment in designing and manufacturing rigid-flex PCBs, they can often reduce overall system costs by eliminating additional connectors, cables, and assembly steps.


  • Q What is your MOQ(Minimum Order Quantity)?

    We have no MOQ limited.Sample and mass production all can support.

  • Q What is needed for quotation?

    FPC&rigid-flex PCB&PCB:Quantity, Gerber file and Technical requirements(material,surface finish treatment, copper thickness,board thickness ,...)
    PCBA:PCB information, BOM list

  • Q Can you manufacture my PCB from a picture?

    No, we cannot accept BMP, GIF, TIFF, or JPG pictures as the manufacturing file.If you do not have gerber file, you can send us sample to copy it.

  • Q Are my files safe?

    We ensure complete safety and security of your files and protect our customers' intellectual property throughout the entire process. Any documents provided by our customers are kept strictly confidential and are never shared with any third parties.

  • Q How long will it take to receive my quotation?

    We will respond your quotation within 24 hours to the quotation requests.

  • Q How can I pay?

    We accept payments by PayPal, cash, bank transfer (T/T),WU,Alipay. If need other payment method please contact us (sienta@sienta.com.cn).

  • Q What's your transport method?

    We use UPS, FedEx, or DHL to ship the boards. If you have your own freight forwarding company, we can also work with them.

  • Q Do you offer free sample?

    We can offer samples, but you must pay for them first. If you go ahead with mass production later on, the cost of the samples will be deducted.We look forward to establishing a long-term business relationship with you!

  • Q What is your standard lead time?

    As FPC&PCB belong to customized products,generally it is 3-7 days for samples and 10-20 days for mass products.The actual delivery date according to difficulty of the products, the quantity and etc.Please contact us to get different product lead time.

  • Q How do you control the product quality?

    We adhere to strict quality control standards set by ISO 9001, ISO 14001, IATF 16949, and SGS. All boards undergo 100% testing and we offer a range of inspection options including visual, X-ray, AOI, and ICT/FCT.

  • Q How many layer can you produce for flexible PCB?

    For FPC, we can produce from 1 layer to 8 layers.

  • Q How many layer can you produce for Rigid flexible PCB?

    For Rigid flexible PCB board, we can produce from 2 layer to 8 layers.

  • Q Which surface treatment can you produce for FPC, PCB and rigid flexi PCB?

    We can produce Immersion gold, immersion silver, OSP, hot air Levelling(L/F), Gold plating,ENIPIG, Immersion tin and etc.
