Micro vias are very small round holes in PCBs, sometimes simply called through hole, used to connect to various circuits. Micro via can be placed anywhere on the PCB, but they are most commonly found in areas where many signal or power lines cross each other to reduce PCB crosstalk and improve PCB signal integrity. Micro via can be widely used in high-speed PCB design , power and signal circuit ...

Blind Buried Micro Vias PCB

Guide to blind, buried, and micro vias in PCB design . Learn types, applications, design guidelines, and how to choose manufacturers for HDI boards.

Here are the main types of Micro Vias : Staggered Vias : This is the most common and less costly method of implementing the Microvias to interconnect the multilayer high-speed or RF signals. By placing an offset on a slightly different axis, a zigzag path is created, as viewed through the cross-section of the stackup.

The Art of Microvia Placement

Use via -in-pad designs for BGAs, filling vias with conductive epoxy or plated caps to support solder joints. Maintain adequate spacing from traces and other vias per design rules, preventing plating voids. In power delivery networks, cluster microvias under planes for low inductance paths.

Design strategies for reliable microvias include selecting laser drillable materials and adhering to IPC-T-50M and IPC-2226 standards.
