FlexiPCB produces flexible printed circuits optimized for Controller Area Network (CAN) communication. CAN bus remains the backbone of automotive networking, with over 70 ECUs in a modern vehicle exchanging data across CAN, CAN FD, and CAN XL links. Our flex PCBs replace bulky wiring harness segments in tight spaces — routing CAN_H and CAN_L as matched differential pairs on thin polyimide substrates that bend around dashboards, door panels, and engine compartments. We hold differential impedance to 120Ω ±5%, meet ISO 11898-2 physical layer requirements, and process builds from single-layer to 6-layer with integrated EMI shielding for harsh electromagnetic environments.
CAN flex circuits for door modules, seat controllers, mirror adjusters, and lighting systems — replacing rigid PCBs in confined vehicle cavities where traditional boards cannot fit.
Flex circuits carrying CAN signals between engine control units, transmission controllers, and battery management systems in electric vehicles. High-temperature polyimide withstands under-hood conditions.
CAN FD flex interconnects linking radar modules, camera units, LiDAR sensors, and central ADAS domain controllers — where low latency and high data throughput are non-negotiable.
CANopen and DeviceNet flex circuits for PLC interconnects, servo motor feedback loops, and sensor networks in factory automation. Dynamic flex designs survive millions of motion cycles in robotic joints.
CAN bus flex PCBs in patient monitors, infusion pumps, and diagnostic imaging equipment where space constraints and reliability requirements demand flexible circuit solutions over conventional wiring.
Our engineers verify your CAN bus schematic for correct transceiver placement, termination resistor positioning, and differential pair routing. We model the 120Ω impedance target against your chosen stack-up and copper weight.
We calculate trace width, spacing, and dielectric thickness to achieve 120Ω differential impedance on flex substrates. Ground plane placement is optimized for return path integrity and EMI suppression.
CAN_H and CAN_L traces are routed as tightly coupled differential pairs with matched lengths. We run signal integrity simulations for bus lengths exceeding 1 meter and data rates above 1 Mbps.
Every CAN bus flex panel is TDR-tested to verify 120Ω ±5% differential impedance. AOI, flying probe, and cross-section analysis ensure trace geometry and via quality meet IPC Class 2/3 standards.
We provide impedance test reports, stack-up documentation, and material certifications to support your EMC and automotive qualification testing.
Every CAN bus flex board ships with TDR impedance test data proving 120Ω ±5% differential impedance — the CAN physical layer specification defined in ISO 11898-2.
IATF 16949 and ISO 9001 certified production lines with full traceability from raw material to finished board. PPAP documentation available for automotive OEM qualification.
Sputtered copper, plated copper, and conductive silver-ink shielding layers protect CAN signals from electromagnetic interference in electrically noisy vehicle and factory environments.
Automotive-grade polyimide substrates rated to 150°C continuous operation with halogen-free, UL 94 V-0 flame ratings. Designed for under-hood, in-cabin, and industrial temperature extremes.
