What is a Flexible Printed Circuit Board (FPCB)
Also known as a flex circuit, it is a type of electronic interconnect that uses a mallable plastic substrate-typically polyimide(PI) or polyester(PET) instead of the rigid fiberglass(FR4) used in traditional PCBs. This allows the circuit to bend, fold, and twist into complex three-dimensional shapes or move dynamically during operation.
FPCB Production Features
Full-Spectrum Production Flexibility with Zero MOQ
Offers versatile manufacturing of various FPC types (single-layer to rigid-flex) from prototyping to mass production, supporting orders as small as 1 piece with no MOQ limits.
Versatile Industry Applications
Provides reliable FPCs for diverse sectors like wearables, smartphones, medical devices, automotive systems, and industrial sensors to meet industry-specific needs.
Strict Manufacturing Parameter Control
Ensures strict control over layers (1-6), sizes (up to 250×600mm), hole diameters (0.15-0.2mm), line widths/spacing, and other critical production parameters.
Comprehensive Surface Treatment Solutions
Delivers multiple surface finishes (Ni-Au, Sn, OSP) with defined thickness ranges for nickel, gold, and tin layers to suit different application requirements.
Integrated Ancillary Service Package
Supplies end-to-end assembly support, customization options (outlines, panelization), and enhancements like stiffeners and EMI solutions.
Flexible Delivery Time and After-sales Guarantee
Offers flexible lead times (3-12 working days) with expedited options, plus 100% after-sales support and pre-production samples for quality verification.
FPCB Manufacturing Capability
From rapid prototypes to production-ready FPCB ( Flexible Printed Circuits), Helptron Electronics provides end-to-end FPC manufacturing with speed, precision, and full material flexibility. Our FPCs power products across wearables, medical devices, consumer tech, industrial sensors, and more.
