Any tip on re-tinning vias and holes? Just fill it with solder and then take it away with a desolder pump?obitus1990 wrote: ↑Thu May 05, 2022 7:48 pmI have an A3000 that I purchased with similar signs of corrosion. I desoldered every single component and socket in the area that had even a tinge of corrosion, then sanded off the solder mask to bare copper, checked for continuity in all traces, cleaned it in an ultrasonic, re-tinned the traces, through holes & vias, then recoated the exposed copper traces with a UV cured solder mask.
You have a lot of work ahead of you to mitigate that if you want to keep the system running...and it will not be an easy desolering job due to the large ground planes the A3000 possesses. I feel your pain.
Also, anybody know where to find a BOM for the A3000? that would be useful, I want to replace the passive components around that area now that I am at it (I already sources a couple of ICs).
