jectors to project the multiple fringe patterns needed for image processing. Lastly, because 3D AOI inspection is an emerging technology, there is an increase in machine costs compared to 2D-only AOI systems. As the industry trends towards
smaller components, more advanced packaging, and increased PCB densi- ty, it is even more critical that AOI effectively covers the entire spec- trum of defects. Clearly, established and widely accepted 2D AOI ap -

got the job done, it did not have the simplicity of the new software. We can optimize the entire line using it, which, again, is key for us since our product mix is entirely our own. Walking a board through the system for a SMEMA check, for example, is rather cool because you can see the board in graphic animation as you watch it pass by the various sensors.” Recently, Hitachi and Yamaha
revealed that they had concluded a contract to partially transfer assets related to the surface mounter busi- ness owned by Hitachi High-Tech - nologies Corporation and Hitachi High-Tech Instruments Co., Ltd. to Yamaha Motor Co., Ltd. According to Suchko, this was not a problem for ECU: “We know that Yamaha is in the procurement process of Hitachi mounters, but we’re very confident in our purchase because we have had nothing but great service with Japan ese suppliers.” He notes: “We almost bought Yamaha before, so it was an easy decision to buy Hitachi/Yamaha; after all, we had Sanyo/Hitachi. Even though it’s the new Yamaha Hitachi line, Hitachi products are superbly designed. You look at them and you can see the thoughtful design everywhere. The way the lid opens and feels solid, also with just enough tint in the view port to make sure that the vision systems work, but you can still see the whole process. We have every confidence in our investment in this equipment.” Suchko concludes: “I guess if a
machine makes you money, then you need to make the logical choice of buying another one; so that’s exactly what we did. These are the top machines in my opinion. If we need another machine, it would be hard not to buy yet another from the same supplier. We are so proud of our Hitachi equipment we keep ‘promo- tional signage’ ready to put up if we get visitors. We have a standing invi- tation to Tom Simpson that we would be happy to show any one (other than our competitors of course) our pro- duction line to prospective buyers of this equipment. That shows an enor- mous vote of confidence in your major equipment supplier.” Contact: Engineering Concepts

A 3D AOI inspection process uses the Nordson YESTECH FX-940 system.
proaches and emerging 3D AOI tech- nologies each have advantages and disadvantages. But using both 2D and 3D AOI ap proaches in combination makes the best uses of both methods, using one’s strengths to overcome the other’s weaknesses. Ultimately, adopting a combined inspection strat- egy of both 2D and 3D inspection methods in a single AOI system can provide the highest level of QA in today’s ever advancing manufacturing environments.
