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

At an EMS I used to work for, our process for first article inspection was to have a human technician do a point to point comparison between the BOM and the PCB. They would verify component part #s were correct per the location, correct polarity and

Here, there are two possibilities - either it is a new board to us (ie built elsewhere previously) or it is a new product for the company requesting the build. If new to us only, ask for a sample PCB. You will need CAD data for pick & place machines

As always, our good colleague Evtimov is right about the AOI and oven. For the AOI you need to make a golden sample board(panel) and test if your machine can catch all defects that you simulated BEFORE the oven. Try to me as accurate to real defects

If you have any kind of inspection, record any faults found. If you've got an RMA process, record any faults found. Should rework and/or RMA's hit unwanted numbers, you may want to include additional inspection in your product documentation during bu

Chris, Some ramblings- Your choice depends on factors like which defects you're looking for, bugdet, quality inspection philosophy, high or low mix environment, sample sizes or 100%, and so on. Are you going to test 100% of the product coming off t

Hello everyone! I'm a student of electrical engineering currently working on a thesis for my BSc degree. It will be about post reflow AOIs and AXIs, and I'd kindly like to ask you for some help with it. I would like to know if there are any standar

Unfortunately no sample numbers. We are building our own products, not a contract manufacturer. We are monitoring AOI, RMAs and rework - this only started in the last couple of months, but top management inclines not to give a target as it may "upset

AOI if needed? I take it your AOI/AXI is not inline. Too bad. Our AOI is the first line of defense against induced errors in the mfg process. It's invaluable. How do you know it's not needed, or that it won't be needed in the future? Do you hav
