58 SMT Magazine • June 2017 can utilize the measurement data. It's re- ally big data, which includes volume in- formation and offsets, everything. With that measurement data, you can optimize and improve the process. Eventually you will get very good productivity. That's the key benefit of using 3D AOI. Las Marias: How do you help your custom- ers understand this so that they can fully appreciate the benefits they can get in 3D? Kim: To persuade customers and help them to understand the concept of 3D AOI, we need a tool. That's the software. Without a good, easy-to-use software, we cannot convince customers. That's what we are emphasizing today. That is the multi-line concept of production management, based on an intelligent platform. Intelligent platform means automation and more intelli- gent management provided by Artificial Intelli- gence (AI). We are putting a lot of resources to develop that area. Eventually, we want to make more automation and less human element in inspection. Without having that kind of strong, pow- erful software technology or automation, it's useless. You cannot handle such big data. There- fore, someone needs to help to analyze the data. That's one thing that we are targeting and we are focusing on. More automation and more intelligent software platforms. Las Marias: What is your strategy for Industry 4.0? Kim: Our strategy for Industry 4.0 is a multi-line management concept. Previously, many cus- tomers had multiple lines, for example, 10 lines and 10 pieces of inspection equipment. This means the user has to manage 10 times of work because each system has no joint connection. Although in the modern day, everything is the same, but actually they work differently. For 3D technology, as I mentioned, we have measure- ment data. If we calibrate the system, the mea- surement data should be equal regardless of en- vironmental change. That means we can do centralized manage- ment. That's one of the things which we are tar- geting for Industry 4.0. A centralized concept so it doesn't matter if it's 10 systems or 100 sys- tems, they will all work like one system. Las Marias: What other developments are hap- pening in the 3D AOI space? Kim: This year we are introducing another new technology. For example, although we have 3D technology, actually the camera projects from top. It means we get the information from the top. That's one of the limitations for 3D AOI. You cannot see beneath the components. This time, we introduced a camera technology from the side as well. Now we can inspect both the top and side. Conventionally, 2D AOI also has a side camera solution as an option, but our 3D side camera is different from others as it has been developed with 3D technology, which is why we call it a 3D multi-measurement camera. We use four side cameras, but each side cam- era has 3D information—the same as the top camera. For instance, when we use top camera to inspect a solder joint, the information may be limited. We still have 3D, but the information is limited. However, if you use the side cameras as well in 3D, you will get solder joint shape, vol- ume, height, everything. It's much more accu- rate than just having the top camera. And then we combine both data to deliver our customer a perfect solution. Scott Kim KOH YOUNG DISCUSSES LATEST 3D AOI INNOVATIONS
