Couldn't tell you for sure as it's been 4+ years since I used the PARMI and 7+ since I've used the Koh Young. I was unimpressed with the repeatability of the laser based PARMI system and I was always impressed with just about everything from Koh You

Yeah, I agree with you. We do the same but Wrong Text inspection is something they have told me we would remove for two years now, but they still won't let me pull the trigger on it. Mainly because our line workers still place wrong reels or mislabel

I'm looking at some used AOI machines. There's a lot of yestech machines that are cheap and pretty new, less than 5 years old. My worry is the brand doesn't seem to exist any more. Can you still get parts for these? Is the 3D stuff good with the
