Caboer’s 4-Layer Rigid-Flex Board for Industrial Equipment is tailored for automated control modules, industrial sensor terminals, machine tool electronic components, assembly line testing devices, and more. It precisely meets the core demands of industrial scenarios: vibration resistance, narrow space adaptation, and stable signal transmission, serving as the core circuit carrier for industrial electronic modular integration.

Adopting a 4-layer rigid-flex synergy structure: the 0.2mm flexible layer offers excellent bending toughness and vibration resistance, flexibly fitting narrow wiring paths, connections between moving parts, and complex cavities inside industrial equipment to avoid wiring damage from pulling. The 0.7mm rigid layer is lightweight yet structurally stable, reliably supporting core components such as industrial control chips, high-density connectors, and power modules, enabling efficient integration of "flexible adaptation to complex structures + rigid fixation of core parts". With precise dimensions of 143.5*20mm, the slender design perfectly fits the narrow-gap installation needs of industrial equipment, occupying no redundant space while balancing integration compatibility and mechanical stability.

Key advantages: ① Full-board immersion gold finish, featuring oxidation resistance and resistance to oil and dust erosion, with low contact resistance ensuring stable transmission of industrial control signals and testing data for harsh industrial environments; ② Solder mask with white characters + through-hole design, clear markings facilitating assembly, debugging, and post-maintenance, enhancing soldering reliability and operational efficiency; ③ 4-layer wiring with scientific partitioning, effectively suppressing electromagnetic interference (EMI), adapting to multi-module collaboration of industrial equipment (signal collection, data processing, execution control), and meeting high integration and stability requirements.

Caboer provides customization for 1-30 layer FPC, 2-32 layer rigid-flex boards, paired with rapid prototyping and efficient SMT assembly services. Covering industrial control, intelligent manufacturing, IoT, and other fields, we deliver highly adaptive and reliable solutions for industrial equipment R&D.
