5.What is blind and buried via boards?
Blind and/or buried vias are similar to traditional, multi-layer PCBs with through-holes in that these via create connections between layers of the PCB. But one important difference is that blind and buried vias do not necessarily connect all layers of a board. This difference permits circuits of non-planar topography to be connected, which traditional multi-layer boards can’t do. This is an important advantage since it economizes the use of space on the board by permitting only the required layer be connected. 

Uniwell circuits applies specific definitions to the various types of drilled interconnections. They are:
● Through-hole via: on that can be accessed from both external layers of the board
● Blind via: one that doesn’t go through the complete board yet can be accessed by one of the external layers of the board.
● Buried via: one that only makes connections with the inner layers of the board and is not accessible by any of the external layer
