Benefits Of FPC Led

  • Versatility

    The flexibility of the printed circuits allows for customization and adaptation to various surfaces, enabling lighting designers to create unique and eye-catching lighting installations.

  • Durability

    The flexible printed circuit boards are resistant to mechanical stress, vibrations, and shocks, making them suitable for applications that require reliable and long-lasting lighting solutions.

  • Flexibility

    FPC LED technology takes advantage of the flexible nature of printed circuits, allowing the LEDs to be integrated into curved or irregularly shaped surfaces. This flexibility opens up new possibilities for lighting design.

  • Space Efficiency

    The flexible printed circuit boards can be designed to fit into tight spaces, making them suitable for applications where space is limited or unconventional form factors are required.

  • Energy Efficiency

    FPC LEDs consume significantly less power compared to traditional lighting technologies, resulting in energy savings and reduced operating costs over the long term.

  • Safety

    FPC LEDs can be designed with protective coatings or encapsulation materials to enhance their resistance to moisture, dust, and other environmental factors.


  • 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.
