PCB for Robotics & Robot Arms: Enabling Next-Gen Industrial Robots
October 30, 2025
Modern industrial robots process hundreds of sensor inputs with sub-millisecond response times while operating continuously in factory environments ranging from -40°C to +85°C, creating extraordinary demands on electronics manufacturing. These extreme requirements — combined with stringent safety standards like ISO 10218 and ISO/TS 15066 — have driven robot PCBs far beyond conventional electronics capabilities, requiring specialized materials, thermal management solutions, and manufacturing processes that meet industrial reliability standards for 10-15 year operational lifecycles.
This guide explores the critical manufacturing capabilities, design considerations, and quality standards that define modern robotics PCB solutions, demonstrating how KINGBROTHER’s 28+ years of expertise enable next-generation automation systems through advanced robot PCB manufacturing and assembly processes.
Robot PCBs are specialized printed circuit boards engineered for industrial robots, collaborative robots (cobots), autonomous mobile robots (AMRs), and robotic automation systems. These boards serve as the integrated nervous system coordinating motion control, sensor fusion, power management, and communication — enabling the precision and reliability that modern automation demands.
