Thanks for your reply. I'm wondering if We have 2 machines, one can do +/-100um @ 3sigma and the other is +/-100 @ 4sigma. And how U come up the solution. thanks

I am not sure where Frank got his numbers but here is what Sigma really means. 1 Sigma is one Standard Deviation, 2 Sigma is two Standard Deviations...(anyone take a Stats class in college?) I am not going to bore you with all the stat-mumbo-gumbo

Dave, I did assume Angela meant components ready for pick up. It would be too time consuming for any machine to measure the component availability prior to pick up. If we assume that the feeder advances in a rate of six sigma ( 3 defects per mio ) t

It's obviously Bertha - the only one of the Butts sisters that was a standard 3 deviate

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

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

Hi There... Sorry to post another query here but I have an existing line for pick & place machine using FUJI NXT II M6 Generation 1. We would like to add NXT modules but then the available modules that we have now is NXT III Generation 3. Is it pos

Hello, I have a few PCB boards i am trying to be manufactured that are miniaturized medical devices. Thus they require IPC Class 3 Specs. However as miniature devices they have limited space, including a 0.4mm pitch BGA socket, which currently has
