That’s how the PCB and parts in the near looks like after the Ni-CD battery has started to leak. Mostly the main PCB and cable connectors are affected, I have not seen damage to the RQDX or Memory Board on my VS2k’s.<\/p>\n
I have no big knowledge about repairing such issues, so have started to read about and will start on one PCB with neutralizing, cleaning, re-wirering, Solder Laquor, and resolder all parts.<\/p>\n
But maybe you know better procedures – so feel free to share.<\/p>\n
So time to neutralize the leakage, and to clean the PCB. I always remove the PCB parts, so that I can verify the lanes on the PCB, and to clean all accordingly.<\/p>\n I use diluted acetic acid to neutralize the leaking fluid. The bubbles shows that both liquids are neutralizing each other. Afterwards I have washed the PCB with distilled water.<\/p>\n More Cleaning and PCB wire checking. On the component side it was needed to clean very much, so the lanes where much more thinner as before, so i have coated them with solder.<\/p>\n There are also about 5 lanes, which were eaten by the leakage, so I need to rewire them by hand. (time to search for the schematics to find the next solter point)<\/p>\n The resistor rig was damaged as well. it is a 4.7k Ohm 10 Pin (but how many watt’s?). The three 74xxxx will be replaced as they are not expensive. The custom chips will be cleaned and I hope they have no internal error.<\/p>\n I have ordered the resistor pack and IC’s and wait for the order to arrive.<\/p>\n","protected":false},"excerpt":{"rendered":" I have got some VS2000 over the last Months.
