You can easily get 99.8% for 0603 and 99.6% for 0402 out from a Panasonic MV2F, and these machines have no adaptive pick-up. To get 99.8% from HS-50 for 0603 or 0402 should be piece of cake. Anyway, is getting 99.8% pick-up = 6 sigma process?

Hi Dave, I think 6 sigma is here to stay. Unlike any other programs like ISO, six sigma goes to the people�s mind. With drastic examples like � you would not fly a plane which reaches its destination in a three sigma probability � you start to think

I am surprise that you get 99.5% pick-up rate out from the HS-50, unless you are refering to 0201 chip size. I can easily get 99.8% for 0603 and 99.6% for 0402 out from a Panasonic MV2F, and these machines have no adaptive pick-up. To get 99.8% from

Angela, besides the sense or non sense of six sigma and related meetings, you will have to break down the component feeding issue into several sections, which are all impacting the feeding reliability. 1. Component dimensions 2. Tape size 8, 12, 16

500 rejected (?) per million placed components is a very good rate, considered that it would be better than 4 Sigma if you name it defects on the board. Or do I incorrectly convert ppm to dpm? * 3 Sigma 66,800 defects per one million opportuniti

I have recently been put in charge of our SMT line. We have to developed a SPC. My questions are: q1. What are the �most� important parameters to monitoring and which of the control charts do you usually use depending of the parameter..? Our line is

| Does anyone know of a contract manufacturing house that can guarantee smt component placement and can verify placement of +/-.015? | | Thanks in advance | Question: mm, inches, or mils? I can do it. However, what is your reliability level? 9

Good luck in your conquest. I have been struggling with the same issues for some time now. I have made the following conclusions. First, it is nearly impossible to establish parameters in SMT to perform X-Bar and R charts. Electronics is not as cl

Even though I cannot answer your question about a good Six Sigma training course, our company has had training in lean which I felt was helpful. You stated that one of your goals was to reduce cost/waste. That goal seems to lend better to a lean ma
