I'm not sure to what degree you are manually crunching this data.....If you can set up the data manually, or parse the data from a recording function, to allow it to import into a database with a formula for Cpk, and everything else you could ever in

Hello EW, thanks for your input, the data collection for measurements such as these can get confusing because you're calculating deviations from set point location to actual placement location and then analyzing the full result. Then there are many o

We have a Viscom SPI S3054QS. Yup, the machine offers a quite good speed. My board dimension is 150 by 250mm. The cycle time is only about 24 sec. The analyze time is only about 10sec. You can make your loading faster, if that's what you needed. I ha

That's hard to quantify. I deal with escapes when they occur, but I haven't kept track of that data. It doesn't happen to often. But when it does, I take it back to the AOI to analyze why it escaped, and change the algorithm to catch it, if I can.

I also have a spreadsheet tool for comparative analysis using criterion weighted scoring. It can be used to analyze any decision, and helps groups reach consensus on why a particular alternative is the way to go. As final steps you can also consider

Dear Ing, Have you analyzed why some RF device aren't operational after washing? An assumption is that failures are related to the ultrasonic energy applied. Other possibilities are for poor rinsing, poor drying, inadequate washing on those failed

If that's the case, let your customer go. I have run into this situation recently. Q. Why do you not run a dedicated line for lead free? A. You (the customer) give less than 12 weeks forcast and expect us to have a dedicated line for your product?
