Hello ricardof, To implement Cpk studies on SMT production equipment, you will require highly accurate glass plates, glass component slugs, accurately manufactured stencils and a measurement system to perform X, Y and Theta positional deviations from

Placement Accuracy and CPK

We are doing a field study to test the placement accuracy and calculate cpk of some machines in our plant. From previous readings, it is suggested that you buy glass board kits from Accuspec, Topline, etc. Is that the easiest/cheapest way to go abo

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

Michael, You need to know the measurement capability of whatever system you use to do your CpK measurement. Ideally you would do an error of measurement study of the measurement process. It is hard to imagine a measurement system that would err on

Dreamsniper, Always remember your ace in the hole when it comes to equipment used in this industry; its complexity! CPK, PPK and various other cost studies are excellent ways to "communicate" to bean counters your situation with the particular mach

We chose the MPM over the DEK. We did real world comparison in our factory with both machines almost side by side last year. MPMs offer a real windows based software that basically takes the operator out of the equation. Besides the basic screen p

Pavel is right...Your Quality Group, customers, and Management will really appreciate Cpk's. We do Cpk's annually, or whenever a major mechanical change (motor, blower, etc) is made. Pavel is correct in saying that Cpk's on most modern convection o
