    Damaged through-hole via

    So I was replacing a set of primary filter caps in an amplifier PSU board. The caps were glued to the board, and when I finally got them loose, I realized I damaged one of the vias when trying to break the glue bond. The trace is still good, but the via is not.

    My plan is to bypass the trace, and solder a piece of wire between the capacitor leg and the next component.

    However, since this is inside a sub enclosure, its possible the capacitor leg may make intermittent contact with the trace or what's left of the via from vibrations. Do I need to worry about arcing at all from this intermittent contact? This is a 200V 820uF capacitor and 125V mains voltage runs through it.

    I don't usually work with things outside of PCs, so I figured I'd post this and let one of the gurus chime in.

    Thanks!

    Do you have any pictures of it?
    I fixed a broken via in a UPS on a large snap-in electrolytic capacitor without any problems.
    Before I fixed it, the UPS inverter would not run, because the protective circuitry timed out because of a missing output rail.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      Don't know exactly how it looks, but shouldn't you be able to fix it with some hot glue? Maybe get some thick tape to insulate where you don't want it to touch?

        Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
        by acedogblast
        This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

        There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

        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...

        Lifted trace, how to glue back down?
        by Widget
        Hi all,

        I have a PCB and one of the tracks lifted. I tried using superglue but no good, didn't stick.

        What have you had success with at gluing down traces/tracks ?...

        The Real Dangers of conductive glue.
        by mitsu2k
        I know many folks on this forum warn against conductive glue and suggest removing it immediately upon site. I'm here to vouch and say these people know what they are talking about. To be more accurate, the glue isn't intended to be and doesn't actually start out conductive. It gets conductive as it is heated by components that get hot. The glue starts out to be a light tan color but as it is exposed to heat, it gets darker and darker until it is a dark brown. I have found that it becomes conductive at the point that it reaches a light brown color on darker.

        Here is an experience I...

        ASUS Rog Strix G17-712LV Laptop Liquid damaged
        by XxMicroSoldering
        Hello Guys

        I have a ASUS Rog strix laptop that I bought recently to fix and the previous owner spilled water on it . He brought it into a repair shop for them to check it out and instead of fixing it they damaged the battery connector of the laptop ! Other than that they damaged damaged nothing . But since the liquid damage the laptop only turns on and the keyboard lights up and then immediately turns off. I really want to repair this laptop and I also have experience in repairing phones etc and laptops and a bit of soldering but the diagnosing part is where I need help with and...
