As the wife of someone here of this list said before, "routing PCB is an
art", and something you should master.
At home, I use just CIRCAD. I do mostly single-sided boards, routed
manually (I LOVE TO DO THAT, believe me!) and every jumper I must use, I do
like a top layer trace. So I just change top layer mask for jumpers :o)
If you NEED to do double sided boards, you have some tips:
- Do you know that hundred-pack of resistors that jameco sells? That
1/16th W small things? They have a wire SO THIN that you can put then into a
pcb hole WITH The component or the socket.. So you can solder it on top and
on the bottom
- Use extra vias for interconnecting top and bottom pcb traces. Use a
small component wire to join then
- Be an expert on the art of doing single sided boards :o) I did a 1MB
memory board for use on an EPROM emulator, using 32K SRAMs taken from used
486 motherboards (yeah, 32 chips on a board, I'll need a good PSU for this
toy!) with two rows of 16 chips, with only some jumpers. I can post a photo
of the board just in case you are interested to see (and hold on because
I'll put the entire project on the net as soon as I can make it work with a
good program,
- Use a decent program. Eagle is good, but besides the autorouter,
nothing beats Circad :o)
