Harvey,

? All good info. 

Thanks.

If I ever come up with a money making idea with a pcb 
board involved, I may have to have my boards made, But I don't ever see 
that happening. 

Make sure that you can legally do this with the PC board package you
have.  EAGLE and other "free" versions have a "no profit" restriction.

DesignSpark has no restriction. I don't think Diptrace does either but I would have to verify that.

Who knows, maybe in a time saving way if the price was 
right, but I need to be realistic as I have many other interests/hobbies 
that need some of my time. :) 

Not that I'd know anything about that...........

:):):) I was told once that my hobby was "collecting hobbies".

That said, when I decide to do something I 
go all out to do it the best I can so all this info is great. I am going 
to use Muriatic and HP for my etchant for now.

I started out many years ago with photoetching, KPR and Kodalith
negatives.  Photo stuff was fine, the KPR was nasty stuff.

I tried some presensitized boards, with varying results, negative
density is absolutely critical.

Went to toner transfer, which has been working for a long time. Needed
double sided boards and ended up making each side and epoxying them
together.

However, the designs got so complex that I needed plated through
holes.  That ran the limit of what I could do at home.

Tried Oshpark (and they're very nice, good quality, price depends on
the size of the boards), then I tried a Chinese firm, somewhat
different boards, but not too much.  Oshpark was ENIG (gold plated),
Chinese is HASL (Hot Air Solder Leveled).  Either works.

So I outgrew, if you would, what I could do at home.

Good luck on your projects.

Harvey

You likely did much more than I even plan to accomplish. Small and simple for now.
