Designing a flexible printed circuit is fundamentally different from designing a rigid PCB. Bend radius constraints, dynamic flex zones, coverlay openings, stiffener placement, and material selection all demand specialized knowledge that most PCB designers encounter only occasionally. FlexiPCB bridges that gap. Our design engineering team has reviewed and optimized over 5,000 flex and rigid-flex designs — from single-layer FPC cables to 10-layer rigid-flex assemblies with impedance-controlled differential pairs. We catch the issues that cause yield loss, field failures, and costly respins before your first prototype ships. Every quote includes a complimentary DFM review. For customers who need deeper collaboration, our full design service covers schematic review, stackup design, layout guidance, and production-ready Gerber file optimization.
Ultra-thin flex designs for smartphones, smartwatches, earbuds, and AR/VR headsets. We optimize fold geometries, minimize layer count, and specify the thinnest viable stackup to meet your enclosure constraints while maintaining signal integrity.
Biocompatible material selection, hermetic sealing considerations, and IPC Class 3 reliability requirements for surgical instruments, patient monitors, and implantable electronics. Our DFM reviews verify compliance with FDA and IEC 60601 manufacturing standards.
High-temperature material selection, vibration-resistant trace routing, and IATF 16949 process compliance for battery management systems, ADAS sensors, LED lighting modules, and under-hood control units. We design for the -40°C to +150°C automotive operating range.
Lightweight flex-rigid designs for avionics, satellite systems, and radar modules. We specify materials that meet outgassing requirements (NASA low-outgassing), high-altitude thermal cycling, and MIL-PRF-31032 performance standards.
Impedance-controlled routing for 5G mmWave antennas, high-speed SerDes interfaces, and optical transceiver modules. We calculate insertion loss, optimize via transitions, and select low-Dk materials to preserve signal quality at 25+ Gbps data rates.
Dynamic flex designs rated for millions of bend cycles in robotic arms, pick-and-place machines, and industrial actuators. We engineer trace routing, neutral axis placement, and material selection for continuous flexing applications.
Share your schematic, mechanical constraints, and performance requirements. Our engineers assess the project scope and identify the optimal flex PCB technology — single-layer, multilayer, or rigid-flex — for your application.
We design the layer stackup based on your electrical, mechanical, and thermal requirements. This includes selecting base materials (polyimide type, copper weight, adhesive system), defining bend zones, and calculating controlled impedance targets.
Every design receives a comprehensive DFM review against our manufacturing capabilities: trace/space, via sizes, pad dimensions, coverlay openings, stiffener placement, and panelization. We flag potential yield issues and propose optimizations.
For full design service customers, we provide routing guidance for bend areas (curved traces, staggered vias, copper relief), impedance-matched differential pairs, and power distribution. We verify that no vias or plated features fall within dynamic bend zones.
We manufacture your prototype in-house, test electrical performance, verify bend reliability, and share results. If design changes are needed, our engineers iterate rapidly — typically within 24-48 hours — to finalize a production-ready design.
Once the design is validated, we release production Gerbers with optimized panelization, tooling, and test fixtures. Our engineering team provides ongoing support for ECOs, cost reduction, and design revisions throughout your product lifecycle.
Unlike independent design houses, our engineers work directly on the factory floor. We design for our own manufacturing capabilities, eliminating the guesswork that causes respins and yield loss when design and fabrication are disconnected.
Every flex PCB quotation includes a complimentary design-for-manufacturability review. We catch issues — trace width violations, bend radius problems, coverlay conflicts — before you commit to tooling, saving you time and money.
Our engineering team has reviewed over 5,000 flex and rigid-flex designs across medical, automotive, aerospace, consumer electronics, and telecom industries. This experience means faster reviews and fewer surprises.
Submit your design files and receive a detailed DFM report within 24 hours — or 4 hours with our express service. Every report includes specific, actionable recommendations with annotated screenshots of potential issues.
