Thanks so much!Conductive ink would be simpler to use. You need to clean the board thoroughly and use the conductive ink.
Remove the battery and solder two wires and get a separate battery holder connected.
Use a magnifying glass and a pen light torch and a multimeter to see which connections are dead.
it will take time but it is worth it.
150 solder joints are low-count and you are lucky!
These pens are felt-tipped with a typical middle size line width; I have used them long time back. More recently we used silver paste for electrical connections we did not wish to take the risk of high temp. I used a fine brush to make signal connections and thick brush for power connections. Once we baked it at 120-150C it was a very good conductor (could not be measured with a regular multimeter) but lacks flexibility. The paste we bought has 60% solid with 40% silver content. The solvent was nitromethane and amyl acetate.I wonder if any of the conductive pens is fine enough to repair traces on the shown board. Personally I'd absolutely prefer to substitute broken traces by thin copper wires. Another point to consider, epoxy IC packages are not fully hermetic, electrolyte may have entered and cause malfunction.
Bad recommendation and must not be followed for cleaning electronic items.Hello Bob,
I would highly recommend you use some white viniger soaked into a used toothbrush to neutralize the acid from the backup battery spill. Then clean it with isopropyl alcohol to remove the rest of the viniger.
Save your vinegar for your salads.
I do not know where you received this information.
Um, you cant neutralize acid with another acid.Hello Bob,
I would highly recommend you use some white viniger soaked into a used toothbrush to neutralize the acid from the backup battery spill. Then clean it with isopropyl alcohol to remove the rest of the viniger.
Use Kynar wire for your trace replacements. If you're in Australia, you can buy the wire from Wiltronics. It's 30AWG sized wire coated in insulation.
If you live elsewhere, it shouldn't be difficult to obtain. Just do a Google search.
If you find that you need to attach a wire to an IC lead, then obtain a fiberglass pen to remove the corrosion. Once again, do a google search on it. A fiberglass pen is excellent in cleaning up solder joints for resoldering as well.
If you do all the work and it still doesn't function properly, you may have to remove some IC's to see if any traces underneath have been compromised.
Good luck on this endeavor and please keep us posted on your progress.

Relayer
