What is a Microvia?

Microvias structures can be found in High Density Interconnect (HDI) printed circuit boards.  These are structures being defined by the aspect ratio of a hole, which is the ratio of the length or depth of a hole to its preplated diameter.  They are miniscule holes drilled by a laser in multilayer circuit boards to create the connection between layers.

IPC-2226 1.5.2 HDI Types (I, II, & III of VI)

• TYPE I: (1 + n + 1) Laser Microvias on Both Sides of the Board.
• TYPE II: (1 + n + 1) Laser Microvias on Both Sides of the Board, with Buried Vias in the Core.
• TYPE III:  (2 + n + 2) Laser Microvias on Both Sides of the Board—may Have Buried Vias in the Core.
