Hello Diego, what kind of statistics you want to collect? From SPI, AOI, Pick and place maybe? Alexei is right, it a complex thing you wanna do. I would suggest doing it line by line in the beginning so you can better define what exactly you want or

Hy all, i'm in need for some data about the electronics market: - general Industry Data of SMT and SMT Assembly - SMT-worlwide Production / Turnover - ratio of THT / SMT - Structure of productions cost (Parts, PCB-Assembly, Final Assembly, Investmen

I am just implementing a Statistical Process Control to the SMD. A few simple questions: 1. Is it necessary to perform a sampling plan for suppliers inspection? 2. What are the basical points to control ourself and inspection at a supplier? I mean th

I like that "Lies, dam lies and statistics." thats a riot, only because its SO TRUE. Ill remember that i'm sure ill be able to use it sometime. My company does a lot of those graphs and charts that all relate to things that make no sense. I'm in c

I've never heard of this before. If your solder paste is at the correct temperature, and your process is under control you should have an acceptable print the first time. This sounds like a terrible waste on time and paste. Set up a DOE to prove tha

Just to nitpick a little, collecting defect data and reacting to it really isn't an SPC function. Cal's recommendations (determine critical processes, assess process capability and acceptable limits) are spot on and are pretty much the definition of

We have the Trion machines. Orbotech support has been more than fair. The learning curve for our particular machines is steep. As with any equipment you get out of it what you put into it. The machine does point out defects well, but the statisti

Fastek, where'd you get your statistic on #2? If you could, please send a link. -------------------------------- PS-I took out my 2 other posts because they were deragatory toward countries and schools. We don't want this forum to be a flame war

I finally figured it out - in my manual it shows as a "63:Overflow" and says it has run out of memory for management information. I finally realized they were talking about the MIS statistical data of feeders, heads and mounting programs. I cleared

MTM. Wow, people still do that huh? The problem I have with MTM, it assumes everyone performs things in robotic type motions. The best time study is one that relies on sound statistical methods, and across multiple operators. MTM, however, is gre
