So i am a quality inspector and i am having issues with the immersion silver PCB. I have found the via holes to be somewhat filled and i wanted to know if anyone knew it this is a CLASS 1, 2, 3, ICP DEFECT or what it is at all?

I agree. Just thinking.. could it be copper plating issue as well? anyway, would be interesting to see some photos. Sounds like solder (from HASL process, wave or even poorly washed SMT solder paste) to me.

I would recommend that you have some of the subject vias micro-sectioned and examined in a SEM to determine exactly what is the nature of the problem. I can support this type of analysis (www.semlab.com).
