What is Flex PCB?
Rigid-flex PCBs combine flexible and rigid board technologies in a single application. Multiple layers of flexible circuit substrates are attached to rigid boards externally and/or internally, allowing the board to be twisted, folded, and rolled in three dimensions.
This 3D design capability offers greater spatial efficiency than standard rigid boards, enabling optimized component placement and more compact devices for space-constrained applications.
Our Capability:10+ years manufacturing experience providing complex multi-layer rigid-flex for commercial applications to high-reliability mil-spec printed circuit boards.

Frequently Asked Questions
What is your MOQ for flex PCB?
We have no strict MOQ. Prototype orders start from as few as 5 pieces. For mass production, typical quantities range from 100 to 10,000+ pieces. Whether you need a single prototype or a full production run, we’re happy to support your project at any scale.
What is the standard lead time?
Prototype and sample orders are delivered in 5–7 working days. Standard mass production takes 2–4 weeks depending on order quantity and layer count. Rush and expedited services are also available for urgent projects — contact us for a custom timeline.
What files do you need for quotation?
Please send us your Gerber files (RS-274X format), NC Drill files, and a Pick & Place file if available. A BOM (Bill of Materials) and assembly drawing are also helpful for assembly orders. We accept ZIP, RAR, and direct email attachments.
Do you offer custom stack-up
Absolutely. We design custom layer stack-ups tailored to your impedance, thickness, and flexibility requirements. Simply share your target specifications, and our engineering team will propose the optimal stack-up before production begins.
What materials do you use?
We primarily work with DuPont Pyralux, Panasonic Felios, and Taiflex base materials for standard flex and rigid-flex PCBs. For high-frequency and high-speed applications, Rogers, Taconic, and Isola materials are available on request. Adhesiveless and adhesive-based constructions are both supported.
What surface finishes do you offer?
We offer ENIG (Electroless Nickel Immersion Gold), immersion silver, immersion tin, OSP, and HASL. ENIG is the most popular choice for flex and rigid-flex PCBs due to its excellent flatness, solderability, and shelf life. For high-reliability applications, ENEPIG is also available.
