A tombstone-sometimes called a Manhattan skyline, crocodile, leaning tower or space rocket-is a chip component that has partially or completely lifted off one end of the surface of the pad. Tombstones may be caused by solderability variations on terminations; volume of paste; surface area of pad; variations in thermal demand of pads; solder mask thickness; paste under parts; limited placement force; and nitrogen usage.
