Ball Stacked Features and Benefits
dram ballstack µZTM Ball Stack technology incorporates package stacking

  • Increased memory density within the same footprint
  • Flexible design for a single, two and four layer DRAM solution
  • Low profile enabled by leveraging solder ball height
  • Short trace lengths and wire-bond interconnections ensure high electrical and thermal performance
  • Exposed back surface of the die provides good thermal management
  • Test before stack option results in near 100% final package yield
  • No board-level underfill is required, providing the option for rework
  • µBGA® technology provides design flexibility to utilize wire or lead-bond interconnect technology, perimeter and/or center-bond orientation, polyimide or low cost laminate-based substrates
  • Standard CSP/BGA assembly, materials, and SMT processes
  • Lead-free compatible
