In the past year I was responsible for developing and leading a Team focused on AOI, Evaluation, Justification, and with a full ROI required, supporting a HMLV manufacturing environment. If you have in these economic times the additional resources t

PizzaFred, Scott mentioned lots of good ideas. Take one of your boards to each vendor and see what it takes to program the board how long it takes for it to become online. I've found some that are easy to program, but require 40 or more assemblies to

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.]

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

hi my company is planing to purchase an aoi system to be used inline. is there anyone out there doing this, if so do you use all the machine options (pattern character recognition, bad board marks, correct part polarity...) or do you dumb it down(pa

Board fabricators commonly use Barco AOI to inspect film. The AccuMatch compares pixel-to-pixel of the Gerber data to the image seen by the AOI camera. It's slower than design rule checking, but has definite advantages [like lower falsing]. Unfortu

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 opti

Good Morning Roger, The Mirtec's can be adjusted to lower your false call rate. This can be done by reducing the matching percentage for each componnent but the result of this action is that the machine becomes less selective. If you lower them too

Start with a definition of what you expect the AOI to achieve at each station. Will your in-line machine be post print? Place (pre-reflow) or post reflow? Rather than buy one very expensive machine to put at the end of the line, maybe a couple of
