AOI Unleashed in Yamaha’s Total Line Solution Powerful AOI Drives Optimum Process Performance High-resolution image capture, the combined strengths of advanced 2D and 3D algorithms, and powerful high-level communication between all inline machines and power management software define the pinnacle of today’s inline automated-inspection capabilities The full power of Automatic Optical Inspection (AOI) comes to the fore in today’s data-driven smart factories – both inhouse and outsource – supporting real-time diagnostics that quickly eliminate the causes of defects, as well as providing guidance for rework operators and informing continuous process improvement. AOI is most powerfully deployed after component placement as well as after reflow, to capture data that can show exactly where any problems are occurring. Leveraging the unique software platform shared by all machines in Yamaha’s Total Line Solution, inspection data combines with feeder and nozzle information from all YS and G5S mounters in the line. If there are problems such as a blocked nozzle or stencil aperture, or feeder or tape issues, the operator is notified immediately. The QA Options productivity package, part of the Yamaha Factory Tools 4.0 management suite, pinpoints the origin to help fix the problem quickly. If the operator is away from the line, the Mobile Judgement app sends the information to their smartphone for a quick decision whether to continue production if the issue is not serious, or halt the line and await corrective action. This real-time defect handling, leveraging closed-loop feedback of inspection data, is an extremely powerful feature that can eliminate the lag in troubleshooting, ultimately ensuring higher end-of-line yield. State of the Art AOI Yamaha’s YSi-V inspection machines come with up to 12Mpixel camera resolution to capture clear images of today’s smallest solder joints, high-density interconnects, and chip components. YSi-V systems offer standard and optional features for multimode AOI that combines the best aspects of 2D, 3D, and other inspection techniques including laser height checking. Highspeed 3D inspection – now 25% faster in the latest release – can detect slope gradients to assess solder-joint quality and make accurate pass/fail contour judgements. In addition, 3D moiré phase-shift pattern analysis quickly identifies coplanarity problems and floating components that challenge ordinary 2D inspection. On the other hand, innovative 2D-inspection modes are great for isolating features such as exposed copper and, with full-colour camera and white illumination at various angles, can extract slopes quickly and effectively to analyse solder-joint shapes. Optional infrared lighting enables YSi-V systems to catch defects that visible light sources cannot distinguish. Such a wide range of capabilities lets users create a comprehensive inspection strategy to achieve reliable defect detection with low instances of false calls and fast tact time. There is also an optional four-direction angular camera that provides additional views of the sides of components. This feature provides valuable support to the operator at the repair station by making enlarged images and wide-area images available and including several built-in test routines. 3D Solder-Paste Inspection Leading electronics manufacturers are also adding inline 3D solder-paste inspection to make high-speed, high-accuracy assessments that regular in-printer 2D inspection typically cannot provide. The Yamaha YSi-SP inline solder-paste inspection machine integrates fully into the Total Line Solution and measures surface area and height, adjusting its own focus to correct for board warpage. Yamaha’s hybrid 2D/3D expertise combines 2D contour extraction with phase-shift analysis to eliminate noise from captured images, thereby ensuring extremely high accuracy. The YSi-SP automatically loads board data and conveyor width and can feed back printing information and cleaning instructions to improve print results. In addition, bad marks are supported to help avoid unnecessary processes downstream. Optional features include ultra-high resolution to inspect solder paste for 0201 (0.25 mm × 0.125 mm) to 03015 (0.3 mm × 0.15 mm) chips, as well as bonding inspection to check the integrity of dispensed adhesive and detection of foreign substances on the board surface. More Power for Process Improvement Further extending the benefits to be gained from 3D inspection leveraging the Yamaha Total Line Solution, Image Viewer Is a new tool that provides an important and powerful boost to historical analysis. Accessed through the new Dashboard feature recently introduced to the Factory Tools 4.0 software suite, Image Viewer helps analyse and improve processes by storing and organising the inspection images from any assembly.

Advertorial Controlled white lighting enhances solder-joint analysis Fotos: YAMAHA MOTOR EUROPE N.V Clear, high-resolution images are essential for process analysis within the history file for each unique board ID, the user can click directly on the defect flags to access all the images related to the selected location. This includes not only AOI and SPI images, but others such as pickup alignment images captured by the mounter. It’s yet another fast and powerful way for users to gain valuable insights and improve processes more quickly and efficiently. The YSi-V inline AOI machine integrates fully in Yamaha’s Total Line Solution Yamaha Motor IM SMT Section, a subdivision of Yamaha Motor Corporation, has a complete line of high-performing, compact, and flexible surface-mount placement machines, screen printers, flip-chip hybrid placers and dispensers, and optical inspection machines including the YSi-V and YSi-SPI series that leverage state of the art imaging technologies and advanced 2D and 3D inspection algorithms. Most importantly, inspection machines integrate fully in the Yamaha Total Line Solution to share data with screen printers, mounters, and software productivity tools, on a level that industry-standard interfaces cannot achieve. The result is faster, more precise diagnostics that can pinpoint the causes of defects and drive continuous process improvement. Customers worldwide trust the combination of Yamaha’s Total Line Solution, united by the Factory Tools 4.0 suite and productivity tools like QA Options and Mobile Judgement, to keep raising productivity, quality, and business performance.
