John and Reinhard do you have any references for your recommendations?



I'm afraid my information was in a telephone conversation back in the
early 90s when I was investigating the best way to deal with ni-cad and
other alkaline battery corrosion and called a number of battery
companies (this was prior to the Internet). The advice given has been
tested subsequently on countless pinball and video game MPU boards by
many people and the results are positive. I wrote several articles in
our industry trade magazines to get the word out, and have subsequently
posted on my web site more info.

It doesn't always work, the corrosion can be too extensive for
economical repairs, but boards that have been treated as advised have
rarely failed if they worked after cleaning (and corroded IC sockets,
etc. replaced). Boards where traces are missing are normally too far
gone, but have been saved with extensive repairs.
