Cycles To Failure

Thermomechanical, power temperature cycling (PTC) and vibration analyses were performed on a 313 staggered pin PBGA package using plastic and viscoplastic disturbed-state damage models. An accelerated finite element failure analysis was performed using a newly developed procedure. Validations were performed using published PBGA test data. The disturbed state concept was used to model the disturbance (damage) accumulated in PBGA solder joints subjected to thermal cycling (PTC and TCT), vibration, and vibration coupled with three distinct temperatures. 2D FEA plastic and viscoplastic models were created based on a diagonal “slice” of the PBGA. This allowed the most critical solder balls (under the die and furthest DNP) to be analyzed in the same model. The thermal cycling results indicate that the solder balls under the die are the most likely to fail. The vibration results indicate the solder balls furthest from the package center are most likely to fail. The vibration results, coupled with distinct isothermal temperatures, indicate that as temperature increases, the cycles to failure decreases.

Element Failure

This paper describes a progressive damage failure model which is making an attempt to predict damage growth and ultimate compressive strength of notched laminates subjected to uniaxial compression. A non-linear finite element programme is developed to perform the ply-by-ply stress analysis and numerical results are compared with existing experimental data [1,2]; the agreement is acceptable.
