Tombstoning

Also known as the Manhattan Effect or Chip Lifting, Tombstoning occurs during Surface Mount Technology (SMT) processing when the chip component stands on one end.  Alpha can aid in the identification and rectification of this defect’s root causes, including pad design, placement accuracy and pressure, and the reflow profile.
