Paper Abstract

As a result of the relatively low intrinsic damping in printed circuit boards, vibration and acoustic energy present in the operating environment may excite vibration modes in the PCB that lead to deleterious effects in attached vibration sensitive components, such as MEMS gyroscopes. An investigation of the use of sandwiched layers of microfibrous metallic cloth in contact with the PCB to increase damping was investigated. Tests were performed for both vibration excitation and acoustic excitation. The initial results indicate that mechanical damping can be increased through this approach.
