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

In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

Your process makes a bigger difference. What I have seen is ICT done early is better than AOI done more than a half shift later, and AOI done early is better than ICT done more than a half shift later. For high mix/low volume, I would go with AOI whi

In-Circuit Test is the best method for ensuring solder joint connections. It is a much more reliable than AOI. An ICT machine can ensure solder connections are made for array package devices such as BGA, PGA, etc... AOI is best for component I.D.- is

Can anyone provide for me their prospective regarding AOI vs. electrical test? Which is better for generating REAL benefit in providing customer with a marked increase in defect free product? Thanks for any input you can provide.

In circuit testing is expensive up front because of the fixture cost but the tests are fast. AOI programs can be develpoed in less than a day but take longer to run. If you have good test coverage, in circuit would be a better choice in my opinion-if

I have used all of test and inspection techniques available out there: AOI, AXI, Flying Probe, ICT, and FCT. The reality is that they all have a place in manufacturing based on the type and complexity of product you bild, the industry it is intended

I have just been assigned to look into the ionic chromotograhy test on our PCBA but I have zero knowledge. Could anyone help to explain what is this test about? Is it a) a destructive test? b) What is the measurement unit of this test? c) What is th

Thanks for ur help. But i dun think i will call u bcoz i am in MALAYSIA. What i need is just information of how to carry out or design a test to test for the PCBA reliability. If u can send me some infomation on this, i will be very appreaciated. Tha
