Year of construction: 2025, condition: new, functionality: fully functional, the Seamark XC1000 X-Ray Component Counter: Smarter, Faster, and Fully Automated At Active-PCB Solutions, we know that accuracy, efficiency, and seamless integration are not optional, they’re an essential part of our manufacturing process. That’s why we’re excited to introduce our new Seamark XC1000 X-Ray Component Counter which has just been installed on our shop floor by Advanced Manufacturing Solutions Ltd. The next-generation offline X-ray component counting system is designed to redefine how we manage and verify our SMD component inventory. You can find out more about this new technology and how we intend to put it to full use below! Introducing the Seamark XC1000 X-Ray Component Counter Precision Counting Powered by AI Leveraging an advanced AI algorithm, this intelligent Seamark XC1000 X-Ray Component Counter system provides 99.99% counting accuracy for all SMD components sized 01005 and above, meaning we can say goodbye to manual errors and time-consuming reel unpacking. The XC1000 counts 1 to 4 reels simultaneously with no unspooling, no guesswork, and no downtime. Ergonomic Design Meets Automation The XC1000 features an ergonomically designed workstation where the operator can sit comfortably and monitor the easy-to-read counter screen. With an automated stage movement system and anti-pinch safety design, reel handling is simple, safe, and efficient. The unit is compact and mobile, thanks to built-in wheels for easy relocation. Smart Labeling and Real-Time Integration Mislabeling and manual input errors are inevitable and costly. However, with its error-proof labeling function, the XC1000 automatically detects and recognises each reel, instantly printing the correct label via a TSC industrial printer. This intelligent workflow is further enhanced by seamless real-time integration with MES, ERP, and WMS systems, enabling live data exchange and automatic result uploads. Built for the Modern SMT World The XC1000 is built to handle the full range of reel sizes (7”–15”), heights (5–80mm), and component types, including moisture-proof bag packaging, bulk materials, and JEDEC trays. Its amorphous silicon flat panel detector delivers sharp, high-resolution images with a 430mm × 430mm field of view, supported by four optional cameras for automatic barcode reading. Industry-Leading Database & Cloud Intelligence What sets the Seamark XC1000 X-Ray Component Counter apart is its dynamic, global X-ray component database, which includes: 15,000+ material profiles 60 million+ testing images 700,000+ core reference images Weekly updates with 160,000 new images Over 8.6 million classification training images This continually evolving database ensures compatibility with 99.2% of global components. Updates are cloud-synced monthly, keeping the whole system current and reliable.
