The trend toward smaller device geometries has increased IC functionality and speed. With smaller dies, heat dissipation and the thermal characteristics of the package play a significant role in chip reliability. More and more the critical factor in determining IC reliability is not the IC itself but the package. At the system level reliability depends on matching the thermal expansion properties ofthe die, interconnects, package, and the PWB to avoid thermal differential expansion due to internal or external temperature changes.Package engineers must also consider thermal and mechanical stresses associated with the manufacturing process in order to reduceany manufacturing induced defects. During the solder re-flow operation temperatures in excess of 220°C are realized. This high temperature, combined with moisture absorption in...

::::::English Description:::::: PakSi-E is a versatile 3D quasi-static electromagnetic simulation tool for electronic packaging. With this userfriendly tool, engineers and designers can address and resolve electrical performance issues in their IC packaging designs in a timely manner. PakSi-E is the only 3D quasi-static extraction tool on the market that provides whole package RLGC parasitic extractions. As shown in the above figure, small features like wires, vias, solder balls and pads must be modeled in a 3D model to generate accurate high requency SPICE subcircuits.Even though 3D modeling is essential to high frequency simulation, many competing products on the market still use the less accurate 2D or 2.5D for whole package extraction because of the technical challenges associated with 3D modeling.
