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

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.

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

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

Hello All....we have several hundred PCBs that we need to run with a no-clean solder process and the surface finish is OSP. Our preliminary testing has found that the solder will not wet the entire pad even if the pad is over printed? We have contact

Stefan, Was this machine a Fuji by chance ? Did you buy this machine ? If so why would you or anyone buy a machine sight unseen that is "way overpriced" Just curious.. I have been told by representatives of major SMT machine manufacturers to BEWARE

The letter below was dated December 13, 2006 from Kester's Senior Market Development Engineer. I guess since then they have moved production back to Mexico. We no longer use EM907 as our primary Pb-free paste so I haven't seen any containers in a w

I got an inquiry from one of our electronics labs with regards to their soldering processes. They use eutectic (63% Sn, 37% Pb) solder. For liquid flux they are currently using Kester 186, which is an old-school, full rosin (RMA and ROL1) flux that c
