Optimizing Press Thermal Profiles for High Density Interconnect Coreless Assemblies
Optimizing coreless HDI thermal profiles requires synchronized heating ramps, controlled viscosity dwell windows, and low-rate cooling to prevent warp.
Prepreg Rheology Control in Thin Core Laminate Stacks
Precise control of prepreg minimum viscosity and press temperature ramp rates prevents core squeeze out and micro voiding in thin laminate stackups.
Non Newtonian Squeeze Flow Dynamics and Anisotropic Glass Weave Permeability under Non Isothermal Lamination Conditions
Non-isothermal squeeze flow and anisotropic permeability dictate prepreg filling, requiring precise press ramps to prevent dielectric micro-voiding.
Characterizing Dynamic Viscosity and Resin Cure Kinetics in High-Density PCB Prepregs
Dynamic prepreg viscosity and cure kinetics dictate resin flow windows, microvia filling completeness, and layer encapsulation during HDI board lamination.
Optimizing Inner Layer Registration Tolerances and Resin Flow Dynamics during Pressing
Optimizing inner layer registration requires balancing thermal expansion tolerances through four-slot pinning while managing prepreg viscosity windows under staged pressure.
Rheological Testing Conditions for Thin Prepreg Viscosity
Dynamic parallel plate rheometry under controlled 2 °C/min thermal ramps defines the minimum viscosity window for thin prepreg lamination success
