Caboer’s 4-Layer Rigid-Flex PCB for Testing Equipment is tailored for electronic component test modules, laboratory testing devices, industrial quality inspection terminals, etc. It precisely meets the core demands of testing scenarios: accurate signaling, lightweight adaptation, and stable reliability, serving as the core circuit carrier for various testing equipment.

Adopting a 4-layer rigid-flex structure: the 0.13mm flexible layer is extremely thin and flexible with excellent bending toughness, fitting flexibly into complex wiring paths and compact tooling layouts inside testing equipment to avoid interference; the 0.6mm rigid layer is lightweight yet stable, reliably supporting core components such as test chips, data acquisition modules, and connectors, enabling efficient integration of "flexible layout adaptation + rigid core fixation". With precise dimensions of 83.2*75.5mm, it fits the installation needs of various test modules, balancing integration space and operational flexibility.

Key advantages: ① Full-board immersion gold, featuring oxidation resistance, wear resistance from frequent plugging, and low contact resistance to ensure accurate transmission of test signals and avoid data distortion; ② White solder mask + through-hole design, clear markings for easy module assembly, debugging, and identification management, enhancing soldering reliability and post-maintenance efficiency; ③ 4-layer wiring with scientific partitioning, effectively suppressing electromagnetic interference, adapting to multi-module collaboration of testing equipment (signal collection, data processing, result output), and meeting high-precision testing requirements.

Caboer provides customization for 1-30 layer FPC, 2-32 layer rigid-flex PCBs, paired with rapid prototyping and SMT assembly services. Covering industrial quality inspection, electronic R&D, laboratory testing and other fields, we deliver highly adaptive solutions for testing equipment development.
