Koh Young combines 2D and 3D imaging to do what most AOI systems cannot do – sense height of objects in the Z-axis. This gives a lot of advantages compared to standard 2D systems: It effectively prevents what are known as ‘escapes’ and cuts down dramatically on false calls, able to sense tombstoned components, lifted pads, leads, and components, upside-down components, and so forth. According to Koh Young´s CEO and spiritus rector Dr. Kwangill Koh, the inner workings of the system are a radical departure from what’s currently being offered in automated optical inspection. Responsible R&R group leader Jeff Lee called it „a revolution in AOI, which is obviously necessary.“
The machine presented in Las Vegas was definitely more than a prototype, although it obviously comes right out of the R&D department. It does not have a name yet. The as well still missing housing around the sensor head gave the few who where invited behind the curtain a good insight in the hardware design. The machine will be available to the market by fall. At the productronica fair in Munich it will be ready to be ordered.
