AOI is very cost effective when you are dealing with that many assemblies. Once you do an ROI, you'll find that it probably will pay for itself within 12 months. The reality that many managers can't bring themselves to do is that if you bring on AOI,

I have been using ICT for a number of years. It is still a viable resource for catching defects in the production process. AOI doesn't catch everything, such as bridging on QFN or J-lead devices (this will depend on the type of AOI and camera syste

We use Photondynamics SV-7550 now. We want to upgrade our AOI because we found that SV-7550 are not very good to detect solder defects. I send samples boards at each company with the solder defects that i can't detect with my Photondynamics SV-7550.

I would go with AOI. Reasons are: --AOIs are faster --They have more coverage. Given, you cannot test the value of components, but the AOI will ensure that all resistors are correct, orientation of ICs are proper and components are present on the

Genny, I would like to correct part of the things that you were told. As far as I know, X-Ray tools are not positioned as tools to find solder volume simply because it is not a strong point for them. An X-Ray image is either a projection (2D transm

When testing components on a PCBA, try to validate coverage for presence, correct, orientation, live, and alignment. AOI is not really great at catching cold solder joints and damaged components, and from my experience an X-Ray is only as good as the

No, in his case an ICT in not out of the question. An ICT, especially with many passive components, can give you piece of mind that the assembly was built correctly. Even with the addition of an automated insertion machine, you still run the risk o

After reflow AOI makes sense because it has the highest coverage of the defects. Problems like tombstone, lifted pins, open solder joints, some shorts and insufficient solder you will not find before oven. I would also not agree with the statement th

Oh, my dear, printer is just a part of the full picture. Without good and stable pick and place what if the printer is excellent???It is all important - printer, solder paste,stencil,P&P,oven,AOI and of course good process engineers or whatsoever are

Teradyne says, "How does one evaluate the competency of a particular AOI system? At the highest level, all potential customers must judge any viable AOI system using the following qualities: * Throughput must be able to match the line rate on the man
