How Robot Arms Are Learning to Wire Circuit Boards

In this episode of The Robotics Business with Fexingo, Lucas and Luna explore how robot arms are being trained to solder and wire printed circuit boards—a task that has long resisted automation due to its precision and variability. They focus on the specific case of Japanese electronics manufacturer Omron, which deployed a new system in its Kyoto factory in early 2026. The system uses force-torque sensors and computer vision to place components and solder joints with micron-level accuracy, reducing defect rates from 1.2% to 0.15%. Lucas explains the economics: the upfront investment of $2.5 million per line, but a payback period under 18 months through reduced rework and faster throughput. Luna questions whether this automation threatens skilled soldering jobs, and Lucas counters with evidence that Omron retrained its workers to program and maintain the robots. The episode also touches on how the COVID-era chip shortage accelerated interest in flexible automation for electronics assembly. The hosts discuss the implications for small contract manufacturers and whether the technology is ready for the broader industry. #Robotics #Automation #ElectronicsManufacturing #CircuitBoards #Soldering #Omron #Kyoto #ForceTorqueSensors #ComputerVision #DefectRates #PaybackPeriod #ChipShortage #Reshoring #ContractManufacturing #Business #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
