Re: Finding an open on pcb

Thank you for all of the help. I really appreciate it. Just so I can
be clear about this let me explain again. I am working on a mixed mode
complex circuit board that has no paper and a lot of custom parts. I
need a quick easy way to follow the traces on the board. The go from
one side to the other and there can be up to fifty lines all grouped
together. I can use my meter or a logic probe but it takes to much
time. Is there a tool that you can use to sweep over the traces to
follow a particular node without breaking into the trace. They make
things like this for tracing AC wiring but I have to be careful on how
big a signal I can inject. Lets say I start at a pin of a chip. I
would like to quickly follow this trace and see where it goes. Using
something like a probe that has a beep or light that gets stronger the
closer you are to the correct path and weaker when you go the wrong
way. Has anyone seen something that will do that?

Thanks again
Russ
