For 0402's, if the operator is paying attention, our equipment Panasonic CM 402/602/NPM's run at about .001%. Again this is dependent on an operator that pays attention to the fail rate. We usually don't have too many problems with 0402's, LED's ar

Yes, I know all that, but I am interested in some real figures from the field. That is, what percentage of mispicks do you experience on average (for large runs, of course)?

JS: The issue is not how efficiently/effectively that you can run your placement machine, probably. The issue is how efficiently you can run that part of your assembly process that is the bottleneck. Other than improving quality, optimizing any pa

To be more specific we have a single Contact 3AV that can run the board in question in 5 minutes from placing the board into the machine till the time it comes out. Volume is expected to be low initially but expected to pick up. It just doesn't fe

The layer count itself isn't going to be what drives yields. What is the trace/space? How much annular ring for vias did you give them to play with? Class 2 or class 3? What's the worst hole aspect ratio? Controlled impedance? The closer you run to y

You can't control what you don't measure. You have provided very little detail other than post reflow costs are high. What defects are attributed to problems experienced prior to reflow? Are these random or recurring defects? You will need to put ea

Hi, I am looking for a Solder jet supplier. Micronic does not support my small dot size LEADED solder paste. I can not use stencil print because my substrate is fragile. I need a run rate of 10,000 dots per hour and 99.99 % dots +- 10% volume. Equip

| Jim McCarten and Dave F, | | Jim - How about a little explanation on your PlacePro 7100 comments? I'd like to know what a "typical SMT board" is and how "thruput is cut in half" by assembling it. Is this typical SMT board something that most manuf

Find out your maximum feeder loading (number of slots taken up, not number of feeders - 8mm, 16mm, 44mm, waffle packs tubes etc), and your likely long term max feeder loading (ie what is in the pipeline, or could be). Next find out your required run
