It depends on what you're doing. Say for component placement verification, a line that's kicking-butt might have time to look at a somewhat different quarter of each board, depending on lots of stuff [eg, board, AOI equipment, line rate, etc.]

Now that's an approach I've never thought of, inspecting a different portion of each board (I'm assuming that you program a few different patterns and run them sequencially, or something like that). I know our stencil printers don't provide that option. I like the option of doing a series of detailed audits instead of skipping around to the same points every time.

Do many of the inline aoi machines do that?

From the manufacturer's perspective, we aim to be able to fully inspect all components within the beat rate of the line and generally do. I'm not aware of any competitive machines that do the random sampling that is suggested above, however it is done in the older first generation paste inspections systems. -- Andy

We do the same quadrent every four boards in placement inspection on a Orbotech.
