Hi Steve-O, Good question(s). This process was set-up by an engineer that had a PhD in statistics, took him a year to develop and then thru it over the wall at us. The biggest problem we saw was SPC to measure solder volume. SPC is good for measu

we have omron, before buy I have evaluated lot of other machines, what I like most is the three ring at different angle lighting which allows pseudo 3-d solder joint evaluation and historgams with statistics, you can see out of total solder joints ho

I’ve used “QI Macros SPC Software for Excel [http://www.qimacros.com/excel-spc.html ]“ It is very easy to use. Here's a step-by-step development of a run chart * http://peltiertech.com/Excel/Charts/RunChtLines.html * http://elsmar.com/pdf_files/p%

This thread is not new, but this is a great question- wish we'd seen it sooner. In our experience, manufacturers are only using 10-50% of their machines' capacity. Many on here will agree that it's common for electronics manufacturers to accept low S

Hi there. I did work with Viscom AOI/AXi combo models for nearly 5 years, ones like X7056. It is fairly easy to understand programming if you have proper training from them - read more about black and white image processing in case you would like to

Phil, In the considerations you make for choosing an AOI tool, you should check what a vendor delivers today and what will it be able to deliver in the future. As the role of AOI in the SMT production line evolves from "detection" to "prevention"

Cpk is sometimes referred to as the voice of the process because it is measuring how tight your process is in relation to the specification limits. A Cpk of 1 means that you are running a 3 sigma process (plus or minus 3 sigma). This means that you

To you all for comment and summary, The following things I like without endorsing (PCB/PCBA stuff - outside the great women in my life [many] and without [mostly]): 1) A good set of design rules 2) A good set of design rules meeting producibility r
