we did this for pad design of pcb and can also use it off- line programming for mounter. we had checked out all the component we used in our factory. we sorted 600 kinds parts using part size(L,W,T) ,number of lead ,shape with over 6,000 parts. a

Steve- We had the same trouble with 0805 Panasonic film caps. We had some tombstoning and open solder joints (non-wetting). We found two problems...like you, we changed our pad design to meet their recommendation. Also, they were able to suppl

Based on what you have said so far it would be worth trying extra pads and as you may know the drainage pads should be a minimum of three times the length of the pads before them to be effective. Also take some parts stick them to a glass plate and r

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to
