The pocket in the tape should be about 30-50% larger than the component (roughly if you look at them, actual spec varies). If the pockets are too small, the manufacturer has fucked up.
What is the MPN and where did you get them from?
The 0.1 uF is a TDK part I have had for some years, the 1.0 uF is one I just got a few weeks ago from Digi-Key, made by Taiyo Yuden.
These pockets are not really 30-50% larger than the part, but they are not so snug that they ought to be preventing the part from lifting.
Anyway, the 0.1 uF part that I have had for a while fed just FINE on my old machine. But, it had different nozzles than my new machine. I have a choice of really small nozzles or ones just a bit bigger. I will try the next size up nozzle next time. Also, next time I have the machine fired up I will check the nozzle vacuum, just in case there's an air leak.
Thanks,
Jon
