Stacked Chip Flexibility Testing Case Study

Target Products

Certain stacked memory ICs available.

Purpose

Qualitatively show the flexibility of the chips

Procedure

    • A mult-die stacked chip was identified, decapsulated and wire bonds removed.
    • The dies were separated using a combination of aggressive solvents.
    • One of the die was chosen for flexural analysis, with an edge fixed to a rigid surface and a displacement induced in the other edge using a micro-dynamometer.

Results of Stacked Chip Flexibility Testing

  • The dies were successfully shown to be very flexible after reviewing the details of the Stacked Chip Flexibility Testing.
