Thanks guys
I'll give scanning a shot and check out Eagle, see if i can replicate an image. How much would the etching materials cost roughly? the PCB is about 83mm x 121mm x 1.5mm
If you want to use a rotating switch that contacts the board as in the original design you might need some kind of tinning or coating on the exposed tracks, bare copper might have problems with tarnishing.
Personally I would try to replace any bad or missing traces before replacing the whole board. Another option would be to scan and recreate the original artwork but have it fabbed professionally. That would take care of the routing to get the exact shape needed, plus you could easily get spares in case something goes wrong during reassembly.
Would prefer to replicate it to original spec. Can I 'tin' the contacts with a layer of solder or does it require a specific layer ?
What is 'fabbed'? I had a look online but all the manufacturers for PCBs seemed rather expensive.. probably alot more expensive then the Multimetre is worth :/
The current traces seem intact.. but some sections seem not in good shape. one section in particular, in the centre circle area, the 'tin' has corroded and scratching that away leaves copper. Some areas are also bubbling.
Being a multimeter, is it possible the condition of the traces / contacts could increase resistance and give false readings if trying to probe voltages ?
