Mike, There was a dipswitch that can be changed that will clear the machine settings and reset everything back to defaults. You will also lose your programs so backing up everything is a must. If you need and/or want to do this let me know and i will

First thing is you should be using a 08MPFX nozzle for a 0603 part if you are using a flex head. Then to check the vacuum you should have received a vacuum gage with a nozzle tip that fits on to your spindle and then you turn on the vacuum in diagnos

UIC has a nozzle specifically designed for 0603's. (UIC P/N 46937042) That's what I've been using with better results than the 08mpf. Even the 08 will overhang the part some. We place 0603's on pretty tight centers so I need a nozzle that wouldn't ov

I remember Metro Nozzles mentioning that they are bringing out a new "blade" nozzle soon to allow closer density placement of 0402's & 0603's than the 08MPF allows. Also noticed that you get far better placement with a 1 mil camera than a 4 mil, coz

Good advises thanks. I'll go thru all nozzles and vacuum check today and tell the programer about PD's and nozzle vs shutter. Should I check at the same time all the vacuum filter ? For the placement test, we use the same feeder at the same position.

Hi Alex, I've seen 2 types of feeder test rigs for sale that cover CP6 feeders, one from Alternative - http://www.alternativesmt.co.uk and one called a GAM20 - I think it was ABtech Europe - http://www.abtech-europe.com. The GAM20 was about half th

We are developing a new product, and some of the designers are proposing QFN packages. These look like leadless QFP's. We don't currently use anything like this, but we operate in a high reliability automotive market. Can anyone provide advice/com

Are your packages mounted on boar using sockets or BGA balls? LGA's are usually no issue and are simple compared to BGA. No issue on missing balls or ball drop issues. However, LGA's need quite a bit of mounting / holding pressures during test and mo
