Hello Technet,

While soldering this ceramic capacitor (http://ipc-technet.groupsite.com/gallery/27235), its looks like that the capacitor suck the solder from the PCB`s pad to the capacitor pad and the color is now grayish and porosity. XRF found Sn, Pb, Cu on the capacitor pad. PCB solderability was good and the profile was SnPb at 225 deg C under Nitrogen. Other capacitors and components on the board look normal with shine soldering.
Can anybody seen something like that before? Any ideas?

Thanks and have a wonderful weekend.
