Guys I hope you will be able to help. I asked our local Fuji agent for a copy of the calculator for inputing the average deviation values and they wont give me a copy too scared we get to know too much, the ironic thing is I had my own copy but my ha

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

Hi Well I don't agree with Mr Fox. Cp and Cpk i.e Capabilitiy studies always yield good results and add vigor to the engineer and the process. You might want to hire a consultant or go to some classes to make sure you do this correctly for your si

Hello Dave, First you must make sure your measurement system is calibrated for accuracy, repeatability and reproducibility. We perform a standard GR&R Study on our CmController system on a regular basis to ensure that the system itself is capable to

Sirs, what would be a good way to judge the reliability/robustness of a stencil printer or chip shooter? Does any equipment supplier specify detailed maintenance schedules? Is there a source of machine failure data (MTBF, etc.)? I not

You can use Cp and Cpk to find out your machine performance and accuracy. Some machine had it own software and kit. ie. Siemens. If you are using Fuji and you can visit the AD. on this web, TIMEKEY. Otherwise, you can use a high precision AOI with

Please let me know your opinion on how a Samsung CP45FV stack's up against a Fuji CP6-42/IP3 machine set-up. I am told that speed is close (Samsung only 2,000 cpk off CP6-42) and also measures up flexibility wise. Any feedback would be most appreci

Hi floydl, I completely understand when it comes to data crunching after long hours of performing measurements, it's the last and most important arduous task in obtaining performance data. If a measurement and evaluation process that traditionally to
