Except for the PCB material, physical properties, и производственный процесс, there is no difference.
Опорное отверстие — это отверстие в печатной плате, от которого отходят другие отверстия., prototypes are requested as a “quick turn” order. That is to say, the customer needs the boards urgently, so the making process and shipment require an immediate approach. This is typically done to meet certain deadlines and incurs an extra cost.
