No takers on the riddle? Read the riddle query carefully and, possibly, refer to the Wiki article on VIAs ;) |

BTW: a riddle for those playing along at home: That whole (stuffed) Philips board may contain MANY, MANY vias of the kind everyone can agree upon. Where are they? --- End quote --- I call them jumpers instead of vias because it's what they are: a jumper with a solder blob in the center at the ground plane side. If they were wires or rivlets soldered at both sides of the PCB, like a homemade via, i would have called them vias. |
