Stiction in MEMS devices can occur during manufacturing, testing, and operation in the field. Veryst Engineering approaches this problem through design and manufacturing processing to assure that stiction is eliminated in MEMS structures.
Veryst used topology optimization to design an additively manufactured bracket for adhesive assembly and then used cohesive zone modeling to predict the strength of the bonded joint.
Knowledge of thin film mechanical properties is important for device operation, reliability, and simulation. Veryst measured the elastic modulus of a low stress silicon nitride thin film using nanoindentation and validated the technique with atomic force microscopy.
The microelectronics packaging industry relies heavily on adhesive bonding to assemble electronic components. Veryst built a COMSOL Multiphysics model of a thermocompression bonding process to help reduce bonding cycle time by simultaneously optimizing material and process variables.
Veryst Engineering helps clients realize high-performance additively manufactured parts. Our strong foundational knowledge in materials science and mechanics coupled with practical expertise in experimental methods and engineering software make us uniquely qualified to solve complex additive manufacturing challenges.
Veryst consults in clean manufacturing, which is common for precision products that are deleteriously affected by particulate, molecular contamination, and human contamination. Key areas are: target contamination control levels for the room and equipment, detection and measurement of contamination, transport and deposition of contamination, removal of contamination, and sources of contamination.
The consultants at Veryst provide failure and root cause analyses using core engineering disciplines to evaluate different failure scenarios. Engineering specialties we apply to failure analyses include: mechanical engineering, materials science (metallurgy, ceramics, polymer science, composites
Veryst works with clients to develop high-performance, reliable, and manufacturable medical devices. We apply advanced characterization technologies, engineering analysis, and sophisticated simulation software to provide cost-effective solutions to time-critical engineering problems.
Veryst assists clients with MEMS and sensors consulting through failure analysis, reliability, lifetime prediction, yield enhancement, micro-contamination analysis, and microfluidics and multiphysics simulations. We provide a synergistic approach of combining analytical characterization, empirical studies, and simulation. Veryst scientists are well versed in packaging reliability as well.
Veryst offers expertise in a full range of analytical tools and techniques for non-destructive and destructive failure analysis. Choosing the right analytical method is critical for determining the root cause of a failure. Some of the non-destructive methods we use begin with high magnification
