Hello fellow experts! Does anyone have a SPI machine that can calculate Cpk for the solder paste height across the PCB or for selected locations? Any feedback will be appreciated.

Parmi SPI does CPK

Thank you Buckcho. This is great. We recently got Koh Young, so I assume it will easy.

Mr. Evtimov, Koh Young and Parmi have this option in their SPC software. You can also choose either Volume, Area, position, height (both in um or %). Here is a screenshot from Parmi. Unfortunatelly i cant find my old Koh Young screenshots. Parmi has

Can you send me a screenshot to see how it looks or a spreadsheet of the data? Do you have to modify anything on your own? Can you do it for some selected components/apertures or it has to be on the whole PCB? Any further info will be appreciated.

Hello, good choice! Koh young makes great reports for cpk. Only one advice. If you take 50panels from production and your cpk seems low, try to group the different kinds of components. Because also cpk on a whole panel would be not good number as wel

My favorite kind of calibration is where the machine learns what it did incorrectly. Then fixes itself! However, there are many types of machines that rely on human feedback as to the results of what it did. nozzle calibrations involve many factors

You have received some great feedback so far. I would like to summarize and add a few points regarding maintenance. You should start (as recommended already) by verifying your component library data. Using the default values from the master library i
