Monopix, forget it. Re-creating the track is not possible in home workshop, period. The best you can do is figure out, if the stubs are solderable and if yes, replace the track of carbon with discrete SMD resistors of appropriate value. If the stubs aren't solderable, you still can do the trick by cautious use of conductive epoxy instead of solder. You have to know the resistance between stubs of course. The printed carbon film resistors that were used in these designs are tricky to design to say the least and, even if you could lay your hands on the chemistry necessary to apply such a resistive layer on an arbitraty substrate, it would be extremely hard to get the resistance right. And by 'right' I mean getting it in the ballpark of +400%/-80% range of nominal value. It's not only about track width, it's much more about its thickness and method of application... Marek |
