AOI inspection after reflow | 1 April, 2013

We currently have an AOI after reflow, and I was wondering how others have thier line setup? Does the AOI operator have to get up and get a board from the oven to run, or should the SMT operator hand the AOI operator a board. The AOI operator does have to make sure that at least 2 boards of each rack get done. But how does the AOI operator know which boards to test, if they are busy with other jobs on the AOI. Just wanted to know how others felt about the situation? Please let me know any suggestions you may have. Thanks

It sounds as if you have your AOI set up off-line, and you're "AOIing" a sampling of the PCBs produced. If that’s the case, then the responsibility of who drives the inspection really depends on how you configure it. If it's based on the number of PCBs, then I would say it's the SMT Operators responsibility to insure that the sample PCBs get pulled for inspection. If you base the sampling on time, then the AOI operator should be instructed to pull a PCB for AOI every "so many" minutes.

Do you have a number of lines that are all feeding sample PCBs to the same AOI? If so, then I would look at the duties assigned to both the SMT Operators and the AOI Inspector. Based on cycle times of their individual tasks, you should be able to determine who has enough time to perform this task. And then set the sampling criteria up on either a PCB count, or time period, based on these findings.

Just my 2 cents. Others might have differing opinions.

I have to agree with you. We do go by piece rate not by time. Also who is supposed to make a process, the Man.Eng., or the lead? I would think the Man. Eng and the lead should make sure everyone is following it?
