I saw zigzag tracks on some PCB layouts. What is the actual requirement and advantage of having this kind of tracks?

There is no advantage for fabricators or assemblers. In high speed memory busses, designers zigzag the traces to keep all of the traces within a certain length of each other.

I figured out how to do the first one (I used a multiplexer with addressable latch--works like a charm) Really, it's perfect. My new problem, though, is using this signal to get a string of lightbulbs on. Is a relay what I need? If so, who makes

Thoughts on having AOI catch components that are supposed to be non populated???

It is a very interesting thought. However, teach all positions on the PCB might be challenging if you don't have them in the file. I think it is a smart think for OEMs as they would have all the resources to control their files. For CEM I don't see i

I have been doing this since day one of getting the AOI. It just seemed logical. I don't know what type of AOI you have, but what I have found works best is to use solder inspection to catch parts that are loaded into a no-load location. Move the

Has anyone used their AOI to try to catch components that may be inadvertently placed in a location it shouldn't be? Every once in a while our equipment may drop a part onto a PCB and that part will adhere to pad. So the question has been brought u

We are a CEM and do exactly what you describe i.e. teach the image of a non-populated part and apply to all no-fits for that package style. Works very well with our equipment (Yestech)provided the visual signature of all your parts are sufficiently d
