PCB vias
Vias are crucial components in multi-layer PCB boards, serving as electrical connections between layers and fixing devices. They can be classified into blind vias, buried vias, and through vias, and their design impacts parasitic capacitance and inductance, which can affect signal quality in high-speed circuits. To mitigate these effects, designers should carefully select via sizes, use thinner PCB boards, minimize unnecessary vias, and optimize power and ground connections. Placement of grounded vias near signal layer changes and reducing pad sizes on high-density boards can also improve signal integrity.
Parasitic Capacitance and Inductance of PCB Board Vias
Via holes are important components of multi-layer PCB boards, with drilling costs typically accounting for 30% to 40% of production costs. They serve as connections between layers or for device fixation, and are categorized as blind, buried, and through vias. Designers aim to minimize via size for high-speed circuits, considering parasitic capacitance and inductance effects. Strategies to mitigate parasitics include selecting optimal via sizes, using thinner PCB boards, minimizing unnecessary vias, and optimizing power and ground via placement.
