Hello, We're building some boards with 01005's and the only issue we are running into is the solder is not reflowing. It's the damnest thing, we are having no issues with the printing process or placing the components, the two areas we thought we wo

I haven't worked with anything as small as 01005s, but something you didn't mention is the %metal of your paste. I just switch from 90% to 89.5% (AIM NC257-2) and could tell the difference. Just an idea...

Interesting thought. Our paste is 89.2% according to the data sheet I have, but it still might be worth trying the 84-86% syringe blend. Thanks for the suggestion.

What is that garbage. How about you add flamer to like and dislike. I would have used it at least 3 times in this thread alone.

I forgot to add that we are using a 3 mil stencil. It seems like to me that may be there isn't enough flux left when we reach liquidous?? About half of the solder spheres do melt and wet on each pad, but the top half of each solder joint is just the

you are seeing a typical issue that is caused when such small volumes of paste are printed....there are several reasons for it..the tiny amount of flux in the small deposit becomes exhausted much quicker then it does in a larger deposit ( the flux ma
