I wonder if you could push this to exempt any board with SnPb paste applied to the entire board as long as it has fine pitch parts? hmmmmmmmmmmmmm

I would hope that the committee is at least intelligent enough to insist that exemptions be based on the use of parts w/o coarse pitch equivalents, but we are somewhat evidence challenged in that respect.

Greetings, Is there a Mil Spec or IPC spec on how many times you can wave solder a PCB? I did a search on this forum with no results. Common sense says two or three times. I need documentation.Thanks for any info.

SS EROTION WITH ANY SACK ALLOY IS INEVIDABLE GETTING A YEAR OF USE IS ONLY BECAUSE YOU ARE USING SACKX MOST OTHER SACK ALLOYS WOULD HAVE CAUSED MORE DAMAGE IN THE SAME PERIOD.ED

It appears that the two different boards we are having issues with are the only imersion silver boards that we process. Anyone have simililar issues with imersion silver? Is Dave F. on vacation? I would be willing to consider input from moon man at

I don't know of any standards that apply to hardware at the component level. I would think, though, that unless the spec. sheet for the component specifies cracks there shouldn't be any.

I heard an interesting statement from someone the other day. "AOI machines are a tool that are put on the other end of a bad process." "Why not fix the process?" Interesting concept......eh ?

Does anybody have a practical experience with solder paste dispenser for small-scale production (prototypes, or 10-20 pcs. batches)? What ptich size is realistic? Let's say that the speed is not an issue, but the quality is. - Deni

No dome needed. You should check what type probe you have. You can look here and consult with them: http://www.qualmaxamerica.com/qualmax/leeno/semi.asp?string=ICT
