Hi Pete, I was using only the small and medium nozzles but it happens on both nozzles. No error message unless the delay went past about 5 seconds then a Q servo error and machine stops. Pressing reset and run enables it to continue although it th

Hi to all, thank you very much for your feedback. The part is rotated before inspection; and also tend to be shifted to the same direction of pre-rotation so i think is not correcting misalignment or maybe some settings on shape data are not correc

Humm OK - sort of what i thought - So 90% of the time it's something else - but I assume that if you say that you are fairly confindent that you have a robus process around BGAs - where as i do not. Can we assume that it is actually the BGAs (as so

Hi Chris, A lot of it has to do with your product, t-shooting devices and techs ability. There are ways to determine BGA are at fault. X-Ray is a good way to check for shorts. Insufficients are harder to find. Some people use a dye. They squirt

Chrissie, Are you given any type of budget? If so, Bliss Carts are a good option. http://www.blissindustries.com is a good solution if you're still working in a batch shop. C.F.M.... easier said than done my friend. Some companies never "get

Very nice trolleys - perfect for what i want / need i think. Budget wise - if i can justify it, i think i can have it. Thing is at the moment there are so many problems i can't actually tell how much of the rework is being generated by the storage pr

I have a project I would like to consider a Juki machine for. I am trying to find out if a Juki 2000 series machine can pick up parts from 12mm and 16mm simultaneously with all heads for good optimisation performance? IE are the heads spacing the sam

You need to keep the silver concentration of the solder connection below 2 percent by weight. Concentrations above that level can cause solder connections to fail. We have seen 4 percent concentration discussed. [The 4% assumes a uniform distributi

Mark, On most chipshooters that have a few years of use on them you will find the feeders play a dramatic role in component attrition. I don't know the panasonic software. On Fuji you can get a breakdown of placement errors in different forms.

Melf components are tube shaped so the X and Z values are the same. If you use 3D X-ray you can tell if the joint is attached to the board properly and you will not need the Z-dimension information. This might be a better longterm solution than usi
