Encapsulation of systems in package - process characterization and optimization

Thomas Schreier-Alt; Florian Schindler-Saefkow; Olaf Wittler; Hartmut Kittel

This paper investigates different stress and strain measurement methods usable during packaging of electronic systems. By applying stress measurement chips, embedded fiber optic Bragg grating (FBG) sensors and pressure sensitive multilayers it is possible to determine the stress condition on the surface of silicon chips, on various substrates and within epoxy polymers.

There is a great number of sensors at work in motor vehicles. They act as the sensory organs of the vehicle and convert input variables into electrical signals. These signals are used in control and regulation functions by the control units in the engine-management, safety and comfort and convenience systems. Various measuring concepts are applied, depending on the task.
