Electrical shorts on glass frit seal of ceramic ICs

Has anyone experienced electrical shorting between adjacent leads of a ceramic hermatic sealed IC? If so, can you share root cause and corrective action? The shorting appears to be in the glass frit seal itself but the failure mechanism is unknown. Any similar experiences that can be shared would be greatly appreciated.

Thanks - Linda

Make sure that whoever is pretinning leads are not using a water soluble flux. If they are, make sure parts are being cleaned immediately upon cooling
