What is to much Void? | 13 December, 2004

We are setting up our criteria for acceptance of solder voids. We would like 2% to 4% or smaller as our tolerance. Does this sound reasonable? Are most x-ray machines able to accurately measure at that size? Also, do most people find that 2% to 4% is a reasonable tolerance to use?

Check IPC-7095, 7.4.1.6 For Class 2, 45% of the diameter adn 20.25% for the area.
