Caboer’s 4-Layer Rigid-Flex PCB for New Energy Vehicles (NEVs) is tailored for core components of new energy vehicles, such as Battery Management Systems (BMS), on-board sensor modules, motor control units, and vehicle communication modules. It precisely meets the core demands of automotive scenarios: high reliability, resistance to harsh environments, stable signal transmission, and compact adaptation, serving as a key circuit carrier for modular integration of NEV electronic systems.
Adopting a 4-layer rigid-flex synergy structure: the 0.13mm flexible layer is extremely thin and lightweight with excellent bending toughness, flexibly fitting complex wiring paths, connections between moving parts, and narrow cavities inside vehicles. It avoids wiring damage from pulling and is compatible with installation requirements in multiple NEV areas (e.g., chassis, cockpit). The 0.8mm rigid layer is structurally stable, reliably supporting core components such as power chips, high-density connectors, and sensors, enabling efficient integration of "flexible adaptation to complex structures + rigid fixation of precision parts". With precise dimensions of 53.5*52.25mm, the compact layout saves space, perfectly aligning with the "lightweight, high-density integration" design trend of NEV electronic systems.
Key advantages: ① Full-board immersion gold finish, offering superior temperature resistance (-40℃ to 125℃), oxidation resistance, and vibration/wear resistance. It can withstand extreme temperature changes, vibration impacts, and slight oil contamination in automotive environments. Low contact resistance ensures stable transmission of power signals and data signals, meeting the long-term high-frequency operation requirements of NEVs; ② Solder mask with white characters + through-hole design, clear markings facilitating assembly, debugging, and post-maintenance of on-board modules, enhancing soldering reliability and operational efficiency to adapt to large-scale production in the automotive manufacturing industry; ③ 4-layer wiring with scientific partitioning, rationally planning power, signal, and ground layers to effectively suppress electromagnetic interference (EMI). It adapts to multi-module collaboration (e.g., battery status monitoring, motor control, on-board communication), meeting the strict requirements for signal integrity and functional safety of NEV electronic systems.
Caboer provides customization for 1-30 layer FPC, 2-32 layer rigid-flex PCBs, paired with rapid prototyping and efficient SMT assembly services. Covering new energy vehicles, automotive electronics, industrial control, and other fields, we deliver highly adaptive and safe solutions for the R&D of core electronic components in NEVs.
