Silly question from a hardware ignoramus :
what is a 6 layer (or 4 layer) board ?
I suspect it is to do with the track layour, but all the boards I ever used
were 'double sided' = 2 layer ???
Your in ignorance,
Norman.
PS. Be gentle when you reply !

Thanks for that simple explanation Jerome.
Does that mean that a 4 layer board is really 2 * two layers plus an
insulator between and then when each pair of layers has been etched, the
board is 'glued' together? I mean, it would be difficult to etch out the
tracks in the middle two layesr

What equipment do you use to apply the etch-resist pattern to the
boards, etch them, and then bond them together?
Is it all very expensive for a hobbyist to produce one-off boards for
experiments prototypes? (Probably nothing as complicated as a Q40
board.) In comparison to, say, the cost of
