6 mils maybe? instead of 6mm? We go down to 5 mils and up to 7 with 0603. You could even use a 4mil stencil for these without any problems. The .2mm (.0078")apart however might get you in trouble unless your equipment is rock solid.

Dis agree?!?!?! We solder plenty of them o6o3s at honda and they l00k 0k! Solder balls will always fall off the b0ard when mounted anyway.

0.2mm gap between parts is small and easy to solder short. I prefer 5mils or 4mils.

We had a customer asking PFMEA and SPC/Cpk program. Our company did not have those in our system. Any help is appreciated.

do u mean program as in software? Minitab can do all the basic statistical analysis for your data and give you Cp, Cpk Values. The Cp and Cpk values are derived from estimates from the data (hence necessary to have Confidence Intervals). Regards, Am

in addition to Amols comments I also like Minitab. For FMEA Ford motor Company has a great FMEA program

Is this a new customer or an old one? That's quite a lot to ask if you're not accustomed to performing those analyses.

Air Academy Associates has a nice SPC package that has the PFMEA calculations built in to it. It also does Cp/Cpk/regression analysis, MSA, et al.You can combine it with a reaally user friendly DOE software for about $250. Both use Excel. Brian

is there a posibilities that a lead solder sticked on the pot can be absorbed by a potato when you placed it on the solder pot. to be able to use the pot for leadfree solder.

No, but I'm sure the Potato Board of the State of Idaho would love to help you promote that idea. It might even help keep the spud on their license plates.
