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

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

Is the same marking protocol used when identifying 0603, 0402, etc.. components? For instance, would a 27.4K ohm 1% resistor still have four (4) characters to identify if the body color is black? Any feedback is appreciated. Thanks.

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

I have problemabout fault reject rate at AOI very high, due to inspection letter or marking on IC body. It have uncleary. When I check at raw mat'l of IC it no problem but after pass reflow process it show marking not clear ( Laser marking type). Ple

Hello all, I have a flux over components that affects AOI results in reading the symbols on top of it. What would you recommend to minimize this effect?

What is changing the marking on the part? * Is flux residue coating the part to change the the way light reflects from the part surface? [Run a board with tape on the part, then remove the tape prior to AOI] * Is the heat of the oven changing the mar

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st

Our AOI machine can save various views of the same part number since we all know that different manufacturers will mark parts differently, some manufacturers vary their own marks. We get parts from the same manufacturer but different date codes that
