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

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

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 do

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

We have purchased 2 and will be implementing them in our line shortly. We have one for component inspection and one for paste inspection. We are planning on starting with it "dummed down" and then adding more variables and tightening our criteria a

how does aoi perform inline? is aoi a bottle neck or not? if there are any aoi user please respond. we already know the theory we need the practical thx

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

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.]

Another issue to look at is the efforts that it takes to become familiar with the machine. Where I work we are also looking into AOI machines, and one of our requirements (based on how simple the vendors say their machines are) is that after no more

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
