No paper thing, while I can make some suggestions based on my experience. what is the size of your via? If it's smaller than dia0.4mm, in PCB production process it should be filled by soldermask. So my suggestion is design it to be full filled by SM

I can only say it looks okay for what you need, you will want a dual wave system it can make things so much easier. One thing to check would be the wave nozzle sizes I can see that the conveyor will do up to 15" but thats not to say the nozzle is

If they asked you should try it? Im really interested in the outcome in general. We use no clean on 6 layer multi micro-BGA boards, chip size only goes as small as 0603 though. Around ~500 parts over a 4"x3" area. we haven't noticed any independe

Do you have a solderable surface (walls)? It looks like most walls have a silver arc at the top but some do not (especially the last link) which I interpret that it has been plated (in most cases). Is it possible that the component does not have suff
