Circuit tracer??? Answered

Can anyone tell me how to make a device that can scan and trace an entire electronic pcb and give a schematic result ???

No. Reverse engineering boards is limited to human tracing at this point. I suspect that with the right computational and robotic resources, one could do something more, but that seems a bit out of reach for the homebrewer, although an interesting goal.

No far to complicated. PCB's are made in a very illogical order, they maybe multi layered and not all tracks may be visible.

Nice ide but not going to happen. Best answer would be to take the functionality of the unit and re-engineer it.

I think they exist, but they are beyond the bounds of amateur resources to make and cross-analyse.

I have seen analysers that can make a best guess as to what the circuite is doing but not recreate the PCB.

No doubt China would love the idea!

You cannot make it,

You might rent it,

You can certainly learn to be it !!.................

No such device exists. You would have to be able to x-ray the board and do so in such a way that you can capture each individual layer if there is more then one or 2 internal layers. Even then your having to map it out yourself. Best you can do is build a light box to help illuminate the internal traces so you can make an effort to draw out your own schematic.

In most cases you can find the schematic online or request it from the manufacture. Though you may have to pay a good sum to get it from the manufacture. Service manuels are rarely cheap.

Devices don’t think so I doubt one can be made and if you did make one the database you would need would be the size of the library of congress.

See my Instructable “Reverse Engineering”

https://www.instructables.com/id/Reverse-Engineering-1/

It is on tracing circuit boards and making a schematic of the PCB.
