    Electrical isolation of PCB, need advice

    Hello,

    I have made a quick project, using a general purpose prototype PCB. It's a kind of interconnection board for a part of 220V AC circuit and I cannot be absolutely sure that I will be the only one who touches it, I want to take some precautions. I thought of drowning the whole board in some curing material. The first thought was hot melt glue, then I found some text that says that hot glue is not isolating for higher voltages, but did not find any exact data. So, I need an advice.

    Materials on my disposal are hot melt glue, sanitary silicone, seal maker silicone. Which of these materials is most appropriate for this application?

    Thankful in advance,
    Sasa

    i use epoxy resin,

    you could use silicone if it's not acid or alkaline based cure.
    read the packets.

      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...

      Hi.

      I'm posting this here in part as a memo to self as well as to describe the procedure I used in case anyone else found it useful. I found a lot of the necessary information to make this work on this forum and I figured I would give something back. If this is not the appropriate place to post this, I don't mind it being deleted but I hope it can help other people.

      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...

      Dell Latitude 5511 audible electrical noise
      by Asxetos21
      I have a Dell Latitude 5511 laptop, and lately, a faint but clearly audible electrical (crackling) noise comes from the motherboard, similar to the random clicking coming from a mechanical hdd's heads moving inside it.
      The laptop shows no signs of malfunction, and clearly this is electrical not mechanical, so my suspicion goes to a dodgy component in the power rails (a capacitor or a coil?). I fear this could develop into a serious damage.

      Any advise on how to narrow it down?
      The schematic is available here:
