Blind and Buried Via Plating Technology: Decoding the Precision Process of High-Density Interconnect PCB Manufacturing

Blind and Buried Via Plating Technology: Decoding the Precision Process of High-Density Interconnect PCB Manufacturing

How does traditional plating address the “dog bone effect” and void defects when the aspect ratio of the interlayer vias exceeds 10:1? Technical Principles and Process Challenges Structural Characteristics of Blind and Buried Vias Definition Differences Blind Via: Connects outer layers to inner layers, typically 50-200μm deep Buried Via: Completely embedded within inner layers, aspect … Read more

The Impact of PCB Vias on Heat Dissipation

The Impact of PCB Vias on Heat Dissipation

In natural convection heat dissipation products, the size of vias on the PCB has a significant impact on heat dissipation. However, the exact extent of this impact is still unknown. We will start with a simple product analysis, focusing on the via parameters of a single chip, to study how changes in via parameters affect … Read more
