  • ESD wrist-strap insulation decomposes
  • Now my attention is turning to the computer. It makes a fan noise only after sitting for several hours. I replaced the CPU fan and it runs fine until turned off for some time. When the noise returnes it runs very slow. I suspect the video card fan is the culprit. That's next to try cleaning or replacing.

  • Never use pigtails on cable shields
  • I think you have to remember the setting for John's demo. It was in front of EMI engineers. At DC and low frequencies, there will be no or negligible emissions. But if you work at frequencies where EMI could be a problem, then avoiding pigtails can never be a bad thing.

  • ESD wrist-strap insulation decomposes
  • The good news didn't last long. After letting the PC run for a few hours, I shut it down and restarted it a few hours later. The CPU fan noise was back. I'll have to replace it.

  • ESD wrist-strap insulation decomposes
  • I know a consultant who specializes in ESD protection and control (as opposed to design and test). Hopefully he'll respond to my e-mail.

  • ESD wrist-strap insulation decomposes
  • Package is long gone. Remember, I don't wear them every day like you might do in a lab. I maybe use one 2-3 times a year and have four straps. They all have some decomposition and it's recent. They've been in the same location for nearly three years. There are many other wires in the closet. It is, in fact, my wiring closet. Cable TV, LAN and POTS phone wires all merge there and distribute throughout the house. Plus, many computer cables and power cords. No deterioration on anything else. Maybe they just all aged out at the same time. Maybe one aged out and the goo got the others causing the bare wires.
