چکیده
In a previous study, high-damping printed circuit board (PCB) implemented by multilayered viscoelastic acrylic tapes was investigated to increase the fatigue life of solder joints electronic packages vibration attenuation in random environment. However, main drawback this concept is its inability mount parts on PCB surface area occupied interlaminated layers. For efficient spatial accommodation electronics, paper proposes new version with thin metal stiffener spaced from PCB. Compared ensures utilization for mounting as well capability. Free tests were performed at various temperatures obtain basic characteristics proposed The effectiveness verified sample PCBs numbers layers compare packages.

Piezoelectric-based shunt dampers are developed in recent years because of simplicity in comparison with other methods. In these methods, a part of converted mechanical energy is stored in the internal el...
متن کاملViscous damping of perforated planar micromechanical structures.
The paper gives an analytical approximation to the viscous damping coefficient due to the motion of a gas between a pair of closely spaced fluctuating plates in which one of the plates contains a regular system of circular holes. These types of structures are important parts of many microelectromechanical devices realized in MEMS technology as microphones, microaccelerometers, resonators, etc.T...
متن کاملViscous Damping of Alfvenic Turbulence in Plasmas
We consider viscous damping of both strong and weak Alfvenic turbulence in fully ionized plasmas. We find that the damping is affected by the wandering of magnetic field lines, which makes the effective viscosity scale-dependent. We show that the strong turbulence cascade gets into the viscosity-damped regime at the scale that is larger than the ion mean free path by a ratio of thermal to Alfve...
متن کاملEquivalent Damping Ratios of Structures with Supplemental Viscous Dampers
The current design formulas such as those provided by FEMA273/274 for building structures with supplemental viscous dampers were derived based on the shear building assumption. However, for medium-rise to high-rise buildings that deform in a combined form of shear and bending when subjected to seismic loading, the design using existing formulas may result into an actual damping ratio much lower...
متن کاملThermal Behavior of a New Type of Multi-Layered Porous Air Heater
Based on an effective energy conversion method between gas enthalpy and thermal radiation, a multi-layered type of porous air heater has been proposed. In the five layered structure which is analyzed in this work, there are five porous layers which are separated by four quartz glass windows. The main layer operates as a porous radiant burner that products a large amount of thermal radiative ene...
