What’s on *YOUR* workbench?

If you're average humidity is between 50-60%, you have nothing to worry about, and yes those little bags from Tayda and Mouser will keep your parts safe -- at least until you handle them. If you walk around your house and get a zap when you turn on the lights, then you you need to exercise extra caution, but the reality is that most of the time you have very little to worry about. I've been handling computer chips and ICs for more than 40 years, and I've never fried one (at least not from a static discharge). I have worn those wrist straps, but usually only when I'm working inside of a rack that costs as much as my house, and even then, it probably wasn't necessary.

The bottom line for me is that static isn't a problem in my house. I keep my house between 40-50% relative humidity -- mostly to protect my investments in woodwork and guitars. Both my bench and my desk are grounded, and generally before I handle ICs and processors, I just reach down and discharge myself as a precaution. Unless you're throwing sparks, you don't really have anything to worry about.

Just want to add that you don't always see or feel a discharge. Once it's to the point of feeling it, you're likely at 2kv or higher already.
Even then. It doesn't always kill a component immediately.
I don't wear a band at all time but have a grounded mat I sometimes use and have a grounded aluminum strip on the underside of the front lip of my bench I'll touch.
BBDs and CMOS are especially susceptible.

Not to be that guy, but as I've had it explained to me, the pink or blue bags aren't shielded, they're resistant only. That is they don't build up static charges on themselves as other plastic bags do, as I understand it. The metalized shielding bag is meant for shielding against electrostatic discharge.

Yep. Can zap right through the pink ones
 
When anyone here who has a doubt about ESD or is interested in ESD has time, I suggest watching this


It's an hour and 20 minutes but a very, very very good presentation.

Edit. It's also the most entertaining one probably ever made. It also covers the somewhat discovery of ESD, which is phenomenal and sad.

That's a very interesting video. Thanks for sharing...

SUPPOSED to be in California, but the estimated delivery date is 11 days. Their address is 40 miles from my house, and it was listed as IN THE USA.

"Supports dual power amplifier without blocking the capacitor to ensure high and low frequency signal distortion."

Yup, sounds like it's in the U, S and A. As long as the capacitor is not being blocked and the distortion is guaranteed at both high and low frequency, it sounds like a great deal.
:rolleyes:

There's a video of a guy testing a tone generator on youtube, and he mentions something about capacitance in the end path of the circuit causing noise in the signal being generated. I think he meant that....lol

The Chinese to English translation on AliExpress is AI now, and it is a LOT better than the old stuff. Really works well.....

And I was quite pleased that the tracking number immediately was in the possession of USPS instead of going into limbo and eventually disappearing like fake shipments do. I did get the unit 3 days ago, and THERE'S NO INSTRUCTIONS. GAA.

He's going to email me a high res picture today....

Got a request for another one. I don’t like using these jacks but they’re all I have right now. I’m always afraid they’re going to short out on something.

Looks *sweet* Great job!!!

After I learned to read, I asked my mom what it meant by when it rains it pours. She got this concerned look on her face and said "Honey I hope you never find out". Unfortunately I think everyone eventually learns THAT!

It's a really good watch when you have the time. The story about jet propulsion labs blowing up really sends the whole point home.

I had heard about the "famous" catastrophes, but not that one… the power of a diverse team of talent is invaluable.

Great video! Like listening to Feynman talk; I don't have the acumen to comprehend most of it, but it's entrancing.
