Is there a way to make PCBs at home without any etchant chemicals ?
Thanks

a mechanical router is one way.

copper tape to laydown the traces is another.

buying punched and etched boards is another.


Those are the ones that come to mind quickly.

MILL the pattern with a CNC router. This takes a special machine, and
special software. Etching is MUCH simpler, and actually gives better results, with
proper care.

and there are etchants which are really cheap, relatively safe, and even
some which can be reused forever.

i don't consider "glue the tracks with copper tape" really a serious
method.
then i would rather use wire wrapping.

Perhaps not necessarily at home yet, but I was reading in "Electronic
Design" (a trade magazine I get at work) about Xerox working on a
semiconductor inkbased on a poly compound that can be used to print
electronic patterns.

Supposedly, they can actually "print" working transistors (however,
slower and larger than the silicone counterparts).

This will be an emerging technology, but it isn't quite ready for
prime time. In the mean time, without chemical etching, one could
still:

1. mechanically etch (milling)
2. wire wrap
3. simply solder the components together (make modern art) ;)
4. use your imagination....

Of course, some of these aren't PCBs.....oh well...

I seem to remember the idea of copper tape as a means to let students
make a fast circuit in the class in a matter of minutes.

This site came up on a google. see the bottom of the page.
