Microvia Fill Ratio Control

2007 IEEE International Symposium on Industrial Electronics, 2007
A control law for microvia fill process optimization is proposed in this paper. The law enables linear growth of either microvia fill ratio by applying nonlinear control of cell voltage or plating current density, implemented as a set point trajectory for a potentiostat or galvanostat, respectively.

Optimum concrete filling ratio for partially filled noncompact steel tubes

Thin-Walled Structures, 2019
Abstract In this study, both experimental and analytical investigations have been carried out on noncompact Circular Hole Section (CHS) steel tubes with partial concrete filling. A total of nine specimens are tested as cantilever under flexural loading.

New criteria on the filling ratio and impedance ratio effects in seismic response evaluation of the partial filled alluvial valleys

Soil Dynamics and Earthquake Engineering, 2012
Abstract An extensive numerical analysis on the seismic site effects due to local topographical and geotechnical characteristics is carried out. 2D configurations under incidence of vertically propagating SV waves is modeled with the aid of HYBRID program, combining finite elements in the near field and boundary elements in the far field. The filling

Research on the control of overburden deformation by filling ratio of cementing filling method with continuous mining and continuous backfilling

Environmental Science and Pollution Research, 2022
Underground resource exploitation has seriously damaged the surface ecological environment and underground water system. As an effective control measure, the filling mining process has greatly reduced the surface subsidence. As a branch of the filling mining process, the continuous mining and continuous backfilling (CMCB) method solves the ...
