Finite Element Analysis

  • Ph.D. level staff with broad expertise in analysis for design and failure analysis.
  • Analysis capabilities that can align with all aspects of DFSS, DfM, FMEA, and reliability calculations.
  • Simulation capabilities of thermal, stress, thermal-stress, shock, vibration, drop test, fracture mechanics, and multi-physics analysis.
  • Simulation tools such as ANSYS, Abaqus, LS-DYNA, Simcenter3D, and Comsol, with geometry import in all mainstream CAD and ECAD formats.
  • Experience with size scales from on-chip stress in inner-layer-dielectrics (ILD) and through-silicon vias (TSVs), to package, board, and chassis levels.
  • Services include:
    • Package design optimization per thermal, stress, cost, weight, and reliability requirements, among others. Includes performance comparison of different materials: molding, underfill, solder alloy, laminate substrate core and buildup materials, etc.
    • Failure analysis, modeling, and prediction.
    • Failure modes include delamination and crack growth due to temperature cycling and/or static and transient stress.
    • The simulations may be supplemented by testing performed by a network of commercial labs.
    • Examples:
      • SEM + EDS analysis of sectioned components
      • Shadow MoirĂ© warpage tests;
      • Mechanical testing of materials and components
      • Ultrasonic mapping of delamination
