Constitutive Response of Electronics Materials

Modal testing circuit board assembly of an electronic apparatus by laser vibrometry

“…Data on vibration modes, vibration decrement and other modal characteristics are also necessary for the verification of finite element models used in the development of electronic systems [7] and in the computer design of new materials [8]. With knowledge of eigenvibrations and vibration velocities, it is possible to calculate the dynamic stress field distribution in bench testing as well as under real operation conditions of electronic equipment.…”

“…Today laser vibrometry is extensively applied in dynamic testing of various printed circuit boards. Quality control approaches are developed for fault inspection of electronic equipment and its components and for optimization of circuit board arrangement [3,6,7,[9][10][11].…”
