Recently I got some information in the mail from HTE Corporation in
San Diego. They sell a pcb prototyping system that enables you to make
single, double and multilayer printed circuit boards. It consists
mainly of a plotter that draws the traces on the pcb with an etch
resistant ink. The plotter also has a drilling attachment to drill the
holes and vias. The system also includes a tank for the sodium
persulphate etchant.

The boards it produces are not plated thru holes. So soldering must be
done on each side of the board. How reliable and how inconvenient is
this?

Multilayer boards are made by first making a double sided board and
then making layers on flexible laminates and then soldering the layers
to one side of the double sided board.

I would appreciate if any fellow sci.electronics netters who are
experienced in making pcbs would comment on this system. Of course,
I would like to hear from anyone who has the HTE system. But this is
a new product and I'm not sure that anyone who owns a system will have
access to the net.  

Any comments posted to this newsgroup or emailed to me will be greatly
appreciated.
