Dear all, i want to know what is the highest achieveable CPk value of Panasonic Panasert model NM-2858/NM-2859. Thanks

Something the "placement guys" don't tell the customers... Cpk is an easily "massagable" number. You just take some data points and reduce the variation a bit, or even play around with your spec limits, or a combination of the two to get the highes

Simple question... Not so simple answer. It depends largely on process spec and honesty of the people running the test. Most will jump to throw out the flyers as "special cause". So if you didn't set the spec and didn't witness the run and measu

Hi guys I am looking for any info on cpk values IE fcp6, fip2,fip3 What are the variables to consider for placement times and part sizes. Cheers

John, You realize the DT-651 machine from Fuji will allow you to do CP and CPk data as well as calibrate your feeders. Something to think about.

Dave thanks for the info

Several points: * Consider that your Cpk is probably different for both placing large and small components. * Probably your routine placement rate SB the speed you use to monitor the accuracy of your process. * Some people use a calibrated glass test

We have talked about Cpk many times here on SMTnet, discussed source of glass slugs for placement assessment, and talked about placement Cpk a few times. Search the fine SMTnet Archives to find those threads to provide you with additional background.

Here is a useful website that defines Cpk: http://www.itl.nist.gov/div898/handbook/pmc/section1/pmc16.htm For placement equipment, the manufacturers typically give you a glass plate, where the intent is to measure how far off the centroid you are
