I’m slightly confused about how a via establishes an electrical connection between the copper surfaces of a double-sided copper clad PCB. My understanding is that a via is a hole in the board where the layers should be connected.Is the idea to drill the hole then fill it with solder?
Via’s are plated (after they are drilled) on a regular PCB. On home etched boards you would need a wire, solder filled, or a grommet (compressed) to connect the different sides.
This is one reason prototypes with a large amount of via’s are often outsourced to be made by a PCB company.
