Ultra Smooth Foil Interface Mechanics in Multilayer Board Lamination
Ultra-smooth foil lamination trades mechanical tooth for chemical bonding, demanding tightly controlled press viscosity windows to avoid delamination.
Modeling High Frequency Conductor Loss Variations from Copper Foil Roughness Profiles in Multilayer Boards
Foil roughness forces skin currents through sub-micron surface teeth above 10 GHz, requiring Huray snowball modeling and low-etch oxide chemistries.
Modeling Phase Delay Instability from Thermal Dielectric Drift in PAM4 Substrate Stackups
Dynamic thermal gradients alter substrate permittivity, causing severe phase delay skew and PAM4 eye closure unless mitigated by ultra-flat glass and low-drift resins.
Non-Equilibrium Microscopic Field Singularity Extraction across Complex Three-Dimensional Treated Copper Foil Geometries
Non-equilibrium field extraction pinpoints microscopic copper nodule singularities to prevent partial discharge and dielectric breakdown in thin PCB laminates.
