Hello,

I would like to ask for cooments/advices about the inspection of small solder deposits inspection (aprox 4 mills). We tried with X ray and Scanning acoustic microscope but it looks like due to the small size, we could not be sure to get all the details about micro voids, surface level differences.

thanks in advance for your help. regards, Guillermo

Since you mentioned voids I take it you are talking post reflow correct?
