That makes all the difference on this planet as to how you should design. People who get the true nature of both professional positions do perceive that circuit board design actually is the more durable of the two jobs. That’s why I ask the question and that’s why I believe most of you had been shocked, since you didn’t expect to listen to the answer they gave. They, similar to the two guys in 2008, they stated, "Oh yeah, board design’s more durable."

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.
