Could not agree more. I know the thoery but the practice it's a whole
different ball park.

Took me sometime to figure this one out. But it's not solder but
tinned. And the process is called pattern plating.
As a homebrewer it is too expensive for me to send boards out to
make. If I could only find out a simple way to make plated thru holes
at home without killing myself. And eyelets and baluns are too time
consuming.
