Most PCB companies classify vias with a diameter less than 150 microns to be microvias. These vias lower the possibility of any type of manufacturing defect since they are drilled using lasers which mitigates the chances of any residue left after the process. Because of their small size and ability to connect one layer to the next they enable denser printed circuit boards with more complex designs. Most HDI printed circuit boards use microvias.
Microvias are used to connect one layer of the board to its adjacent layer and have a very small diameter in comparison to the mechanically drilled vias such as PTH (Plated Through Hole).
Microvias are of two types, Stacked and Staggered.
