I’m no scientist and have no evidence to say otherwise. Could all just be a fluke. I just find the topic fascinating :)

Not to worry, this is one of my spare pcbs and just wanted to show this for the sake of others/science. I tested the board afterward and it still works. This sheet has a ton of static the minute you pull it out of the sleeve in the box. I’m just curious that this might be why people are zapping the board.

That and a lot of homes built prior to 1974 in America don’t have grounded outlets. So essentially your PC and all it’s related peripherals are not grounded unless the home had electrical wiring updated.

My home is new construction with grounded outlets and I live in a humid climate. I can’t remember the last time I felt a static shock..

Perhaps. I don’t really use PE sheets or foam so I don’t bother. But for those that do, that could be a good solution.

In response to the post on the front page about a user frying their pcb from ESD…

I noticed this during building. I didn’t use the sheet because I don’t like PE foam. However I wonder if this is causing some of the ESD problems people are having. This thing carries a ton of static in my 50% humidity house.

It’s ESD protection not immunity. A large enough shock to any electrical component will cause damage.

They have ESD protection in both the board processor and an antistatic film in between the case and the pcb.
