Measuring Micro-Fracture Signal Degradation across High Speed Coupling Capacitors
Micro-fractures in high-speed coupling capacitors elevate insertion loss and phase jitter; wideband S-parameter screening catches latent dielectric failures.
Modelling Boundary Slip Velocity in High Frequency Laminates
Boundary slip velocity models replace empirical roughness factors with electron specularity parameters, predicting insertion loss and phase delay up to 110 GHz.
Electromagnetic Surface Damping Mitigation Strategies in PCB Cavity Resonators
Mitigate PCB cavity damping by replacing lossy nickel finishes with immersion silver and controlling surface roughness below single skin depth.
Correlating PCB Physical Etch Anomalies to High Frequency Channel Reflection Losses
Trapezoidal etch profiles and sidewall undercut degrade high-frequency channel return loss by introducing spatial impedance steps that demand mSAP or dynamic CAM compensation.
Temperature Dependent Anisotropy Ratio Variations in Glass Reinforced Hydrocarbon Laminates at Millimeter Wave Frequencies
Thermal expansion alters resin density, driving dynamic anisotropy shifts that detune millimeter-wave phase stability and coupling tolerances across temperature.
