Reply to comment by NovaForceElite in Space65 R3 - already dead from ESD! :( by aleksyandr

how is ESD normally triggered? I always just touch my keyboard without thinking about this risk.

Usually by like rubbing your hand against fabric or something along the lines of that

Doesn't it have to be a direct contact with the PCB for that to happen? I always rub my hand on my sweater or a piece of cleaning cloth laying on my table and touch the keyboard after but nothing abnormal ever happened.

Direct contact? Yes for plastic cases and such

For metal cases? Easily sparks can jump from case to PCB or even for metal plates sparks can jump right to the PCB

Nope, in this case, aluminum (it's metal) case boards have a risk for ESD.

In my case, I'll feel buzzy when I'm touching my Vega when I'm not grounded. Makes me think that the board was "susceptible" to ESD. Even though it never broken once on me.

More metal, more risk to conduct static discharge. Even then, I don't think it's accurate to just say "swap to polycarbonate or plastic case" to simply alleviate the issue.

Then again, I am no electrical engineer. Probably helps a little that I have little to no carpet flooring at my current residence plus the wood flooring probably helped.

I've always been curious about this. I get static shocks from doorhandles and my cardoors all the time, but have never ever gotten a shock from any of my keyboards. Maybe I've been lucky

You can get esd mats but the bracket is annoying. Never used then after my 2nd year of work switching to pure software.

Probably because it shouldn’t be a risk on a reasonably well built consumer electronic.

So this space65 is an expensive keyboard with cheap pcb or something?

Not just cheap, but missing basic ESD protection components. It’s a PCB built by someone who knows nothing about electronics, sold as a high-end electronic.

Some part of the PCB/electronics is touching the case and then the static discharge from wearing socks on carpet or whatever discharges when you touch the case.

I've had ESD trigged by my dog rubbing against my leg. Happens more often in a dry environment. Some people say to use humidifiers to stop it.

Wearing socks on carpet is usually what builds up the biggest charge for me, but you can get static electricity build up from pretty much every daily activity. Then it's just touching something or arcing with something that is conductive.
