I know that there are three vias, blind/buried vias and through hole vias.
But of the products I see will use through hole vias rather than
blind and buried vias, why?
The deciding poingt is Cost..
For example,I want to get a quote with 60*80MM 4 layer PCB design.
I get a quote for 22K USD for 20 pieces, I naturally objected.They said is because it has buried vias. Later, I changed the design sent the gerbers back, price was 150$ in 5 working days.
Unless you have BGA package, don't use any via other than through hole.

Blind and buried vias will cost more on a multi-layer board.
Because their high cost,they are only used on high-density, high-performance systems.
