Cpk for solder paste height | 12 April, 2018

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.

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.

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 3 different ways - they send you two documents in excel called Printing process analysis report, and GAge R&R (this is not exactly for cpk). Additionally in their nice spc software you can do a lot - from cpk, to single panel analysis and trend view.

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

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 well if you have many different components. Good luck playing with the SPC software.
