hi, I'm just attend the BB training for Six sigma project, and have a project with increase the pickup avalability to 99.8%for Siplace HS50 line. want to share infomation with other BB or BB cadidates here, and maybe you can give me some help for th

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?

Oh, and we boil 5-sigma down to 2 out of 10,000 placements as a starting point. I don't know of a single machine that can do 1 million placements in one program. 10K is doable. If we fail there then we start looking at the bigger picture; either r

I�m unclear about � "BB training"??? "BB candidates"? Is BB [Box-??] [Bhote-??] a Design Of Experiments technique like Taguchi? As a start, the following affect the "attrition rate": * Assembly machine program * Machine calibration and maintenan

Stefan: I'm with you. I know that the Siplace machines do that vacuum and visual component check that you describe. I just wasn't sure how the HS50 verifies picks. Same way? So often with things like this six sigma stuff, the definition of the pr

Hi everyone, is someone in this forum familiar with the accuracy of placement. What is that number tell us. Appreciate for your attention.

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

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

yes, it is a Black Belt training,instead of 5 days, it is a 20 days traing during 4 mothing, with a project. I just kick off my project lastday. when the pick up avalability is alreday over 99.5%, how to increase another 0.3%, so difficult, so many
