Any one has experience over solder voids in oscillator capacitor joint could result in high phase noise during the digital performances test? The noise signal was gone after solder touch up. What could be the root cause of the high phase noise?

I haven't experienced this problem, exactly, but I have had issues with noise in digital circuits that appear to have gone away with touch up. The problem was that the customer blamed the noise issue on the solder quality, and he pointed to the fact

I�m working in Solder paste manufacturing industry and my customer has complained the void issue on BGA pad. I�m internally conducting the void test on BGA pad in my Lab. I used OSP furnish board with Sn/Pb and /or lead free component using Lead free

I agree. Voids in plating are bad news and baking will not change that.

Hello, Sometimes you have no choice other than putting uvias in ubga's-pads. I know examples of high-end mass production of products with ubgas having voids. (no problems, but always voids visable in x-ray) I also performed a DOE a while ago to avoid

Via in pad is the most efficient use of space. Blind via seems to be blamed for this. Cross-sections (send me some) will probably show a void still existing in the via or spherical voids aligned near the component pad side. One can estimate the vo

what is your experience about the presence of the voids in the joints ? Are they dangerous and when ?

Do you of reducing hole size of DIMM connector will improve solder voids??
