CST Studio Suite 2011, including CST Microwave Studio high-frequency simulation software, is for electromagnetic problems. Material property descriptions have been enhanced across available solvers. High-performance computing options are available for the frequency domain and the integral equation solver. Time and frequency domain can provide sensitivity information for an arbitrary number of parameters in one simulation run. The trust region framework can employ sensitivity information. Yield analysis for complex 3D models is available at virtually no additional computational cost. The multiphysics flow has been enhanced. Based on one simulation model, the simulation task concept makes optimization feasible, considering electromagnetic, thermal and mechanical aspect. Temperature calculated from the electromagnetic losses can be used to change the material parameters for a consecutive electromagnetic field simulation. CST Mphysics Studio also features a thermal solver on tetrahedral grids.

ProActiv printing technique includes a control subsystem and a set of squeegees featuring embedded electronics. Is said to extend the print process window for consistent printing of small apertures for 0.3 mm CSPs and 01005 passives. Enables next-generation components to be printed next to standard components using a conventional printing process with a single thickness stencil. When activated, energizes paste in contact with or in very close proximity to the squeegee blade. Reportedly does not alter the paste but makes it more compliant, improving packing density of solder particles into apertures and enhancing solder bond, increasing solder paste transfer efficiency.
