Thanks Kevin, this is the best video I've seen directly demonstrating ESD component failure modes. I'd really like to see your follow-up video trying to destroy an Arduino or RasPi microcontroller whenever you have time. I show this to all my friends who have the mistaken belief that modern computer hardware isn't sensitive to ESD, but then waste days or weeks troubleshooting strange unexplainable hardware glitches.

I was working in prototyping a plc and I notice after a few days it start to act weirdly especially the transistor leaking the current. Thank to you to show the unseen process of esd damage on transistor.

Hearing you shuffle your feet back and forth on the carpet reminds me of that Dilbert cartoon where Dogbert is shuffling around to build up static, in a bid to rediscover himself as a modern day Zeus by electrocuting Dilbert :D I recently bought myself a new vacuum cleaner. A brand new, fully cromulated Dyson V6 cordless. Amazing little thing! But the static it builds up is such that I've now taken to vacuuming my house whilst barefoot, otherwise I can't touch the metal tube after I'm done!

Very good demo. exactly what i needed. Im using the atmega 328p mu. after reading the manual and such, i found out that it has this internally, so the easiest method is to just add resistors on all the io pins. i will use this method that you showed on the mosfets tho. ive probably killed a few earlier boards that i made with esd.... when i think about it :P

Years ago and I mean years ago I owned a security company. I installed a well known brand security system and customers were walking across the carpet and touching the remote turning the system on/off and activating the panic alert to police. The company finally duplicated the problems and sent out transorbs to help correct it! Trouble with transorb at that time, they needed to be replaced if hit with a excess charge beyond their rating

@samuelrj23508 жыл бұрын
What physically causes this? Is something in the FET getting permanently charged like EEPROM double gates? Maybe your socks on the carpet charged you positively and the fleece negatively which is why the LED got dimmer or brighter after certain shocks. I'd be interested to see if you'd get only dimmer failures or only brighter failures if you only had one diode in.

It's the blown remains of the metals and other materials making up the MOSFET that form a permanent conduction path that can no longer be influenced by the gate.

@@SomeDudeInBaltimore Thanks for the reply! Do you have thoughts on why the on-state got dimmer, then brighter again after subsequent shocks?

Quick tip for your house. When there is more moisture in the air / carpets / ... - there is more conductivity for the charges. Sometimes even only lightly sparing your carpet with an spray bottle of water is all you need to prevent these charges to accumulate on yourself.

+Richard Johnson here's one for ya - I was working on a design once and was having problems with an old CD series part. This was through hole stuff that this company had stocked in their parts bins. So I swapped the part out with a new one... nothing... then another, and again... nothing... I tested every part in that bin and they were all dead. I then overnighted a tube from digikey, and bingo, worked like a charm. We think that someone stuck their hand in there and zapped the whole freakin bin. That one had me pulling my hair out...

+Kevin Darrah or one time I was working in the EMC lab for a company and we were running contact/air discharge tests on a product when another engineer told us about really weird ESD problem. They were zapping all of the mounting screws of the product, which is no big deal since they tie right into chassis ground, but the strange thing was that the product would reboot when one of the screws got zapped. They spent weeks trying to figure this out, and it turned out the that path to ground through the metal chassis passed right by the main processor. They found that the EMF generated by the ESD was enough to mess with the reset line!
