Could not agree more. I know the thoery but the practice it's a whole
different ball park.
You DO know, doncha, that the PTH is done FIRST, then "SOLDER-
plating" of the
desired pattern (including through the holes!), and etch LAST,
with chemistry that will etch copper, but NOT "solder".
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.
