I've built them with careful, painstaking, point-to-point wiring directly over a fixed ground plane and, in some cases, with GND wires on either side, in intimate contact (insulation to insulation) and glued together with, the signal wire. Longer leads, 10 CM or more were done with coaxial cable or shielded twinax if frequency or sensitivity was high. That with the coax and twinax is interesting. Good approach! Richard said:
When a newbie learns the benefits of such techniques, he figures out how to implement them in PCB as well. If his only contact with the problems one can unintentionally build into a PCB is on a PCB, he's never going to learn to avoid them because they're nearly impossible to fix on a multilayer board. Yes, that's indeed a good argument. I think, if the newbie is really willing to learn, he will learn from each methode. Finally, all roads lead to Rom... Kai |
