Description
Mohammad Taghi Mohammadi Anaei built a laser workflow in 2026 for opening and peeling advanced chip packages layer by layer. Modern packs stack mould, wiring layers, memory, and logic dies, so failures can cascade, yet grinding, etching, and ion beams are slow, patchy, or hard to scale. A single fast-pulse laser platform now handles lid removal, component removal, wiring exposure, and die cross-slicing.
Confocal imaging and electron imaging checked clean surfaces and fine structure at each step. The fast, steady route supports failure analysis, as-built versus as-designed checks, and security inspection for hidden changes. Chip teams gain a practical path to dissect complex packs without destroying the clues they need to diagnose faults.
