Solid caps can blow up?

[Commander Kinsey]

I didn't know solid caps could break. This one shorted the 12V line on a graphics card, unfortunately I have a 2.5kW supply, so the tracks got damaged somewhat, it melted the solder, and ejected itself from the board. Smelt of TCP (a disinfectant), presumably from the evaporated paint?

It wasn't inrushing at the time. The card had been running without a restart for a week or two. It's been running flat out 24/7 for the last year doing astrophysics stuff on Boinc.

I've never seen one of those break though, they're always the coloured wet electrolytics that burst at the end and leak brown fluid.

Looks pretty wet to me. Sticking that right next to the (apparently
inadequately-sized, and certainly inadequately-vented) heat sink for the
SMPS switches isn't a recipe for long capacitor life.

What do you mean? If you're talking about the mess to the right, that's actually a piece of copper track for the ground that's burnt off the paint above it.

Well it has to go somewhere, there's a lot of hot stuff on graphics cards. It also probably needs to be close to the other VRM stuff. Trouble is all these caps are also under the big heatsink for the main GPU which gives off up to 250W. That heatsink covers the whole card, there is nowhere cool.

I thought the ones in the photo were dry. What makes you think they're wet? I thought the wet ones were these kind with vents:

Based on symptoms, there have been cases of capacitors
that needed vents, not getting vents. This was someones
attempt at capacitor fraud, selling cheap electrolytics
in polymer form-factor casings. (This was going on, early
in the intro of Polymer caps as a replacement for electrolytics.)

Companies do this, if they think they can't be sued.

When caps can fail on gas pressure, they have a K or an X
stamped in the metal top, to promote venting at sufficiently
high pressure. The rubber bung on the bottom can
also push out, as a relief mechanism, but is not the
preferred solution. It's better if the vent opens.

When the pH inside an electrolytic is wrong, it eats
through the K or X area and there is a stain on top.
The failed chemistry, even works without bias. The juice
can eat through in 1-2 years of sitting in the box.

If intending to run a vid card at max power forever, it
pays to do a visual analysis and decide whether you want to
fit a third party cooler kit (with better surface blow-down
characteristics). In the year 2022 however, the picking are
slim, so this is no longer an option. One of the companies
good at making those, has stopped. And COVID was only one
factor in the decision. Even if you buy a water block kit, the
board might still need air cooling for the VRM section.

Not that I know of, sorry.

I had considerable interest from ARPA-E back in my early consulting days
(2009ish) for making cheap handheld thermal imagers to look for heat
leaks in buildings, but back then they didn't have any discretionary
money the way DARPA has.

Back then the Measurement Specialties Inc. engineer I worked with (Mitch
Thompson, may his tribe increase) had risen to be CTO of Tyco
Electronics, but even together we couldn't get MSI to build the films
for them--they were only interested in motion detectors.

So the Footprints technology has sat there from that day to this,
unfortunately.

Of course they can. They can also pop like normal caps.
In 2015 I tried putting water on a broken laptop motherboard just to
try out what happens - and one solid cap popped and flew through the
room.

Regardless of how solid or less solid electrolytics are, they can and do
blow. Sometimes in a spectacular manner. As a kid I had a big one almost
the size of a coke can lift off and whizz by my right eye at less than
2" distance. It hit the ceiling and took some plaster out of it, fell
back onto the carpet and smoldered a nasty burn into that.

If the black ribbed thing is a heat sink and gets quite hot then the
placement of these caps so close to the heat sink was not a smart move
on the part of the design engineer for this board.

Just about anything can be made to "blow up", provided one can find a

So, one little cap, shorting, will dissapate something near, or greater
than, 2.5kW for the short time before it blows. 2.5kW of dissapation
in that tiny space is more than enough to cause significant damage,
including "blowing up".

Most of them are not actually inside computer cases, they're sat loose on shelving, so they have a nice cool air intake. They're connected via USB extensions either to a PCI-Express slot, or a multiplexer to connect 4 into 1. It's the first time I've had a failure there. I have blown some surface mount transistors on others, on the rear (non-fanned) side, in the power regulation area.

[Commander Kinsey]

I've set fire to water. I watered a plant behind my 70s stereo amp while it was off and some got inside. Assuming it would have dried out when I used it next, I turned it on and received loud mains hum on the left, and music on the right. This was shortly followed by steam, then smoke, then flames inside the unit. About eleven components were destroyed so I gave up on it. I'm guessing mains shorted into the amp input and everything overloaded?

I used to blow them up for a laugh, but outdoors. Many ended up in neighbour's gardens. The best was a 15V 53,000uF slightly bigger than a coke can cap. The bang caused ringing in my ears. There was no vent on that, until it created its own one.

You can get a nice smell off them if you blow up lots at once. I was an IT tech at a school where they were renovating and building an extension. Irish (ROFL) electricians confused the wiring colours from the old UK stuff and the new EU stuff and put 415V into a classroom instead of 240V. It was the woodwork department where they had three phase lathes, but also one phase computers, 20 per room. The power supplies in the old imacs didn't like 415V and simultaneously exploded, sending smoke everywhere. The teacher phoned me completely confused as to how so many computers would fail at the same time. The only thing that survived was a ceiling mounted projector I'd installed myself, with a surge protector plug. The plug had become a pile of molten plastic, but protected the projector. I claimed on the electrician's new for old insurance policy, got 20 brand new computers, then replaced the caps in the old ones.

That's not what heats the caps. Above them (5mm away) is a 10 inch by 4 inch by 1 inch heatsink with two 80mm 5000rpm fans to cool a 250W GPU. I guess there is no cool place to put them.

I have such a large supply as I have around 12 graphics cards all running at once. Easier to have one big 12V rail.

The input to my house currently reads 243V, 26.4A.

I'm hoping to repair it....

It (the capacitor) made no such choice, as it lacks consciousness with
which to do so.

Instead, wear and tear, likely heat related, resulted in it eventually
shorting. And once it shorted, it then dissapated sufficient energy
within a narrow enough time window to blow up.

[T]

True. I have seen a few make it awhile,
but it is very unusual.

I saw "16V" on the top. If it is facing
12V, then it is not much of an over rating.
But it might be facing 5V.

It could also be "poop happens".

2.KW power supply. Is he arc welding with it?

[Commander Kinsey]

The choice then was made by the designer who cut corners and didn't care if it exploded after 10 years, since it only has a warranty for 2 or 3.

The worst one I saw was a compact fluorescent animal UV lamp from China. The capacitor burst after 3 months use. So I put in a bigger one (higher voltage and low ESD). It seems to be happy now. Still, it was £7.50 for the lamp and the proper ones from big companies are £20-£30, which I've also had fail. Again, heat. Almost an absolute lack of vents on the chassis.

What I don't like about that area, as a co-factor, is
two connectors carrying a lot of amperes for the +12V
and the board is probably using half ounce copper.
It could be that a track traveling near the capacitor,
contributed to the local heating effects. Sometimes, the
exit area near the connectors needs via-stitching to
try to spread the current better into the departing
power tracks or power plane.

If it died purely on ripple current, you'd expect its
neighbors to be showing signs of that too.

But when everything is a blackened mess like that, it's
pretty hard to see everything. Either that black is PCB
charring, or it's chemical attack from whatever passed
as a liquid in the cap. Charred PCB might be more brownish
than black tar colored.

The pattern suggests it may have vented, down low.
Like maybe a hole burned in the cap, or the seal on
the bottom releasing under pressure.

Yes, the current in those cards is absurd. Hence the use of 12V instead of the 1V for the GPU chip. Maybe they should switch to something higher than 12V?

Do they show gradual signs or just a sudden pop?

There was a very strong smell of TCP (normally a disinfectant) when it did it. The area next to it is a copper track, now no longer attached to the board, about 1cm squared which has no sign of blue paint left above it. I assume the paint burnt off.

Not sure where all the carbon came from. Under the capacitor are only minor signs much came out the bottom.

That could be a +5V shorted to +12V fault. I could
see that blowing all the +5V logic.

There's no evidence that the cap was the first part to fail,
or by what means.

The flammability of these parts or their contents can't be
considered as anything better than 'will not sustain open
flame' - but they'll burn if subjected to sufficient temperature
and energy, as will FR4 printed wiring.

Why does anyone need a monster GPU? Serious scientific simulation?

99+ % of PC compute power is used for gaming and bitcoin mining.

Gaming has destroyed the brains of millions of kids. Coin mining uses
more power that many poor countries.

One day GPUs will run LTspice simulations so that you don't need to use a calculator to solve for resistor values.

Absolute and utter mythical bullshit. It's actually been shown it vastly improves a lot of the brain's abilities. You've got to do a lot of thinking all at once.

Actually more than the Netherlands I think it is. It's utterly stupid and I can't believe the greenies haven't shut it down. I use curecoin and gridcoin, but they don't do senseless calculations, they count how much real science you've done on various projects and reward you to offset your costs.

The only thing I liked about the bitcoin idea was keeping the government out, but somehow the US government can actually tax you on Bitcoin profits?! How do they know?!

[Commander Kinsey]

What circuits are those? Must be something pretty complex.

> I'd love LT Spice to run on a GPU, maybe 500x faster.

Is it using multiple CPU cores? If it's a linear calculation, a GPU won't help. GPUs do thousands of things at once, but not that fast.

Just learn to write OpenCL code, how hard can it be?

I found this from 10 years ago on an LT Spice forum:

"LTspice supports multithreading using all threads(cores) of
your CPU if the circuit is large enough.
The majority of the circuits we have had in this group can't
even take advantage of 8 threads. The latest 6 core CPU from
Intel supports 12 threads (6 cores plus hyperthreading) and the
8 core CPU with 16 threads is coming soon.
This means the many cores are good for really large circuits
in the simulation for IC-designs with thousands of transistors."

Or very quick, so you need a very small maximum step size. I've ccertainly simulated circuits that simulated that slowly.

Then recode Berkely Spice in OpenCL code? It clearly wouldn't be hard, but it would be tedious.

You shoot your motherboard with an air gun? I assume you're operating it without bullets or something?

110psi? That's shit. Mine does 5000psi. It's for scuba tanks. Actually I could clean my board with a scuba tank.

For the motherboard, you don't need a strong blast of air, so why get any equipment out? Your mouth can blow dust for goodness sake. Do you get polishing tools out to wipe dust off your mobile phone screen?

Mine has a filter for that, since it's for scuba tanks and you don't want water sat in those rusting them. Pretty simple, just a piece of sponge on the air line.

No country has any age limit, young or old. That's just for the official diving groups with silly regulations. Go by yourself, that's what I do. Buy your own gear on Ebay and go where you want when you want. You don't need lessons, you just read how to do it on google. There's very little to know that isn't obvious.

Drying is the relevant part. Without water there can't be conductivity.

Dust falls off things with air, you don't need water complicating matters.

[rbowman]

Some dive shops get snarky about refilling tanks, not a problem with
your own compressor. The context there is the PCP air gun crowd that
have to sweet talk the dive shop into filling their tanks. A 5000 psi
compressor isn't cheap. There are handpumps if you want to stay fit. 100
or more strokes for 2200 psi.

Oh yes it is. If you're not in a hurry a $170 unit will fill a large scuba tank in an hour.

I don't think I'll try that with a scuba tank. Not unless I hired a fit young lad to do it for me.

My brother-in-law got killed by lightning. Sooner or later you win the
death lottery. That said, I don't hang around on summits when I see a
t-storm moving in and I don't do wheelies in traffic.

I continued digging in my garden in a heavy rainstorm with lightning nearby every 15 seconds. I didn't have a hivis jacket on either!

Indeed, he'd have been much safer with the helmet off :-)

But seriously, chances are if a million people did that, only a few would die.

I haven't taken the covid one, but mainly because it's unnecessary. Most people recover just fine. Me, I never even caught it, despite taking no precautions whatsoever and mingling with many folk. My sister, her husband, and their two kids caught it, after being vaccinated. Shows you how brilliant that idea was....

That may well be true if you have a decent sense of balance. I have difficulty riding a bicycle one handed. No handed makes me fall off in 1 second. I've never tried a motorbike and I'm sure it would end badly.

Yet more of the very interesting senile blather by lowbrowwoman:
"My family loaded me into a '51 Chevy and drove from NY to Seattle and
back in '52. I'm alive. The Chevy had a painted steel dashboard with two
little hand prints worn down to the primer because I liked to stand up
and lean on it to see where we were going."

The gyroscopic effect is your friend. 80 mph on a bike and you have to
work at it to do anything other than a straight line.

I had an old ten speed that I could ride one handed but both my current
bicycles are mountain bikes. Their steering geometry is twitchier than a
road bike.

I tried my friend's road bike once and couldn't get going at all, since the handlebars aren't wide enough, I can't stand those drop things, they're too narrow, not enough leverage.

That looks amazing. I'd love to go through there at twice the speed limit.

I take it you can also take a lot more luggage to go on a long trip?

I detest golf, but the courses are nice to look at.

Gyroscopic Precession ...

[rbowman]

You generally figure it out when you're about 10. My father would launch
me and my maroon and creme Monkey Wards 24" bike down the driveway. It
had enough slope I didn't have to pedal. Eventually I made it to the
garage and had the physics down pat.

Close to 40 years and many bikes later I took one of those MSF courses
and the instructor explained exactly what I was doing. Screwed me up for
a while. I figured you look left, you go left without thinking 'now I'll
push the left bar to the right.'

Of course if you think about what you're doing walking down the street,
you may fall on your face. Science is nice and all, as far as it goes.
