Resistance between Probe and PCB Superior wetting ability prevents voiding For smaller components such as QFNs, micro BGA and LGA, bigger voids could occupy majority of the pad area thus creating a

. X-ray inspection allows each pad to be seen clearly, as well as the large central soldering pad. Missing solder, open and bridged solder pads can easily be seen, and voiding can be measured on each pad, and in the central large pad where higher voiding can lead to poorer thermal efficiency
