That makes all the difference on the planet as to how it’s best to design. Individuals who get the true nature of both professional positions do understand that circuit board design really is the harder of the 2 jobs. That’s why I ask the query and that’s why I feel most of you were shocked, since you didn’t expect to listen to the reply they gave. They, just like the 2 guys in 2008, they mentioned, “Oh yeah, board design’s harder.”

Buried vias are contained within an internal structure, and do not have an external opening. Since buried vias are laminated over, it saves space and allows for more elements to be added to the external layers. When creating small PCBs, there often wouldn’t be enough room to add components if one were to use a thru-hole via.
