Packaging Stress Analysis
Analyses that leverage our expertise in substrate manufacturing as well as Fujitsu Group’s experience in electronics manufacturing.
The heat generated at the time of component packaging causes substrate warpage and gives
stress on the component joints, decreasing packaging yield and product reliability. Analyzing such
problems in packaging in a way consistent with customer’s point of view, we propose optimal packaging
design by suggesting packaging location and stress improvement countermeasure best suited to each
Performing simulations in the early stages of the development phase will greatly reduce the number of verifications for prototypes, resulting in the reduction of cost and time during the development process.
