I may suggest talking with the fellas at SMT Research. They have an awesome tool (POD) that can measure it for you if you're interested in having them do it. From my experience, they are always willing to talk with you over the phone too, so I'd ima

How to calculate CPk of a chip shooter or a pick and place machine? And what's the right CPk? Want to have a rough understanding about CPk.

Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: 1. Cpk's don

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

I would like to know how to implement CPk study on SMT line At this time we have the application to calculate CPk on Chip Placers for X and Y axes repeatability, but I'm trying to find what should I calculate on my Oven and paste printer in a simple

We were talking to a placement machine sales-type the other day. He stated that the Cpk for placing 0201 was 1.33 [Cpk = 1.33, Sigma = 4, DPMO = 6210]. What do you think?

do u mean program as in software? Minitab can do all the basic statistical analysis for your data and give you Cp, Cpk Values. The Cp and Cpk values are derived from estimates from the data (hence necessary to have Confidence Intervals). Regards, Am

stepheniii Unsure how they determine that the process is stable and in control, a prerequisite to calculating Cp, Cpk. A trained chimp smoking a cigar could calculate Cp, Cpk.

The best way that I have found to calculate CPk for placement machines is to buy the kit that is usually provided by the manufacturer of machine. It usually consists of a glass plate and glass components that are scaled. You simply program the mach
