When you look at the capabilities of Combo machines they tend to sacrifice performance when compared to separate X-ray and AOI machines, meaning they don't do either the X-ray or AOI operations as well as a machine that was designed to do only one. A

Can you share some information relative to these questions about your conformal coating process: 1) What process controls do you use for conformal coating? 2) Do you perform manual conformal coating inspection? 3) Do you use AOI for inspecting confor

Hello Before I say anything. Here is one caveat, I work for a 3D paste inspection vendor, I will not mention which. So you can take whatever I say with a grain of salt. Paste inspection will make a difference if you want to put the effort into it ma

Depends a lot on what you want to solve. Very low volume conformation of componpents down to legends, process control or inspection of assembly. Biggest problem is they are resource hogs. Most require constant attention. Any change in component sup

You're right! Whether "Pattern matching" or "Pixel recognition", in both cases, it is the operating person who will make an inference from the results obtained. This makes IPC knowledge the key to AOI usage. "Quality" is never introduced into a pro

I agree with the stand alone option. That way you can sample PCB's from different stages ( print, placement post reflow) In a controled process, after reflow inspection would be ideal.

Hi Lou, If real process control and useful defect data is what you're looking for, Orbotech has some of the best tools available out there.

I posted a similar question a few months ago. Basically, I asked: "Can anyone who is NOT a salesman for an OI company, provide an objective argument for purchasing these very expensive systems." Well folks, not surprisingly, no one has posted a respo

Don�t your recent findings on soldering defects point towards less need for AOI? Besides that, I imagine that with 100% control and having only good prints being processed while the bad ones getting washed and reprint you will see this magical 0%. Sh
