    GEO 33920-56B30 ECU with leaking Rubycons

    What the fuck. Really?
    I was inside my ECU fixing a possibly blown data line when I noticed burn marks around the two 50v Rubycon capacitors. Popping some glue off also took with it the capacitors and...

    Trace damage. Both caps had leaked not once, but twice. They had totally fucked up the surrounding traces and left a high resistance short which in one place had burned a hole cleanly through the board and along another trace to ground. There are indications however this was repaired in 2000 but they replaced the caps with the same ones and twelve years later, it happened again.

      High temperatures tend to do that to caps. Even good brands are not immune.

              Is it possible bridging tiny broken trace
              by chth96
              When I assembled dreamcast I mistakenly fastened long bolt and It resulted in
              cutting tiny trace.
              This tiny trace(Total width of white coating is 5.5mm) is between R337,R343 and IC101 and it is covered with white coating in the below screenshot.


              Firstly I tried to bridging tiny broken trace with my own eyes...But it is totally impossible..So a week ago, I ordered G1200 Digital Microscope and I magnified this tiny broken trace with it.

              But It seems that It is really very tiny trace So I plan to order 0.1mm coper wire from aliexpress in order to bridging...

              Help repairing Yamaha RM1X synthesizer/groovebox - PCB trace for capacitor has been pulled off
              by jshhh
              Hi guys,

              I've been trying to restore this Yamaha RM1X groove-box I bought, and the first thing on my agenda was to replace a bad capacitor that was making it so that the screen was super dim. As I'm a complete novice I went and accidentally pulled off one of the trace pads for the SMD capacitor as I was removing it, pulling up some of the green PCB with it. I've been trying to repair it by gluing down copper tape from where it began to pull off and solder the capacitor on after...atm I've just been attempting to do the same kind of thing on rubbish PCBs I got at a recycling place,...

              Why is my silver conductive trace paint not conductive?
              by SluggerB
              I'm working on repairing a keyboard, there is trace damage on the membrane. So I got my little pen of silver conductive trace repair paint and repaired the trace. Let it completely dry, test it, and its not working. So I take my multimeter out, put it on continuity, touch 2 different area of the paint, and nothing. I put it on resistance, I get OL most of the time, occasionally it might flash to something ridiculous like 17 mega ohms or something.

              Why is this stuff not working? This is what I am using https://www.amazon.com/gp/product/B00B88B9KI

              CMOS battery holder solder pad trace
              by Kemer
              Hi,
              I will add a photo of HP 15 laptop mainboard. The positive side of CMOS battery holder solder pad has been broken. What I want to ask is, the trace of positive pole. If you look at the photo, you will notice red color "A" and "B" letters for two different shades of blue.

              Anybody help?...
