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

Philips Emerald & Emerald-X is specified at max 54mm device. However I have placed 58mm devices. These machines have published accuracies at 0.02mm. Have seen as low as 0.007mm.

Thanks Rob for your meaningful advice. Instead of just a general average time per component, I think if we have 3 averages, 1 per "component group", we will gain significant accuracy in the cost model. For instance, a motherboard may have 2500+ R and

John, I'll throw my bit of confusion into the pot, here. Your limited floorspace, coupled with your technology mix vs. volume mix narrows the scope of your search. You don't say what your budget is, or whether you are looking for speed. I'll give y

The most innovative new technology today is ccoming out of Fuji. They don't really advertise, so if you haven't gone to a show lately you might not have seen it. The machine is call the XPF-W and it sets the new standard for quality, accuracy, reliab

Considering the volume it would seem you are better off to go to a small contract shop. If you let us know what area you are in Im sure you could find one that would be acceptable. You should not have problems with accuracy or lead times with the typ

Hi, An answer to this question is very complex. The amount of components and their type is only one parameter to determine the level of failure. Additional parameters that can influence are: 1. The density components on the card 2. Machine type and
