Hi, I need help to understand further on the via in pad for 0402 requirement. If I were to do the DFM over the brd design which consist of 0402 with via on pad, what is the criteria that I should look for ? I learned that the via in pad does not wor

Most of the older placement machines might not have a 2mm advancing feeder. Here is how I get by picking from a 8 mm feeder without loosing every second component. 1. Define a second component in the BOM. 2. Define this component in the feeder set up

Hello ! That was an one of our troubles. But we decidet it. Our way : 1. Vibrofeeders of Phillips may be ajusted for special ironrails , horisontallylairs , so IC goes permanently and correctly, also we create some acceptable subfeeder for Phillips

for 0402's you should be able to run the turret at full speed, if you need to slow it down it means that your machine isn't set up properly. use the vision number that the manual tells you and make sure your feeders are properly calibrated, poorly c

Hi, We are thinking about starting to use via in Pad, for both BGA and 0402 and 0201 components. Does anyone know how this would effect production. Obviously PCB production is not difficult, but this should only effect production and assembly. R

I am not sure about 643's, but on a 642 machine, the pickup height @ station 1 is critical. Especially on 0402's. The should be a spec, and instruction on how to verify in your maint. manual. Bad pickup height can cause you all kinds of headaches on

What is the level of interest in bulk feeding cpassive devices, caps & resistors, 0402,0603,0805? The component mfgs. tell me in 3 years 40% of the passive caps will be bulk fed. Their is currently about a 10% cost savings with bulk over tape & ree

Hello, We're experiencing about 4% loss of parts (primarily 0402 caps and resistors, few 0603s and 0805s), and the error codes are mostly 12040403 and 1CA0A009. The help manual on error codes is cryptic at best. Can anyone help me interpret these

20%) on particular parts (e.g. 0402 caps) by looking to the part data. After this, we have another threshold (10-20%) that I am continuing to look into. Feeders are suspect, though part data could also be involved, just to a lesser extent than with
