unterschied blind und buried via

Hello.......
Anybody tell the difference between Blind and Buried vias?
With Thanks
 

blind vias are connecting a inner layer to either the top or bottom layer, and the other layer is blind as it doesn't see the via.

buried via is connecting two inner layers, without access to top or bottom layer.

that's different from the regular via that connect top layer to bottom layer and pass through all inner layers.

Regards,
Sakr

Hi jayasuryan,
You could have googled before posting this.
Blind vias are via holes which are formed to connect the outer circuit with inner layers, but DO NOT go through the entire board
Buried vias are via holes used to connect inner layers and are not visible in the outer layers.
I hope you understood now.
The following web page will help you.

In the case of multilayer boards (e.g. 4 layers)

Blind via = Via goes from one of the outer layers and does not appear the other side.

Buried via = via sandwiched between the outer layers and can not be seen.

Hope this helps.
 
Through via -An interconnection between the top and the bottom layer of a
PCB. Through vias can also provide interconnections to innerPCB layers.

Blind via -An interconnection from the top or bottom layer to an inner
PCB layer.

Embedded via or buried via -An interconnection between any number of inner PCB layers.


Blind vias and through vias are used more frequently than embedded vias.
