Too Much Gold Delays World's Fastest Supercomputer

timothy posted about a year and a half ago | from the other-people's-problems dept.

Bug 111

Nerval's Lobster writes "The fastest supercomputer in the world, Oak Ridge National Laboratory's 'Titan,' has been delayed because an excess of gold on its motherboard connectors has prevented it from working properly. Titan was originally turned on last October and climbed to the top of the Top500 list of the fastest supercomputers shortly thereafter. Problems with Titan were first discovered in February, when the supercomputer just missed its stability requirement. At that time, the problems with the connectors were isolated as the culprit, and ORNL decided to take some of Titan's 200 cabinets offline and ship their motherboards back to the manufacturer, Cray, for repairs. The connectors affected the ability of the GPUs in the system to talk to the main processors. Oak Ridge Today's John Huotari noted the problem was due to too much gold mixed in with the solder."

Shavano (2541114) | about a year and a half ago | (#43179009)

Yep. Gots to pay attention. Thick gold on the connector to connector contacts is best, but don't plate it onto the solderable end of the connector, or on the pads on in the through holes. Actually, a tiny amount is good because it prevents corrosion before you have the part soldered on, but it has to completely diffuse into the solder to avoid making a non-conductive boundary layer. If there's too much to diffuse, you're screwed. You'd think the engineers at Cray would know this.

meh... silver is a far better conductor than gold, and copper too. So gold doesn't oxidize nearly as easily... but still seems with the price of gold these days it would be more effective and still less expensive to use silver or copper with a clever super thin layer of insulation than uninsulated gold. Then again, I dropped out of second semester physics after a couple weeks, so I'm probably missing something important about why gold is so popular in electronics.

The Cray engineers did know this. The amount of gold used was well within the bounds of the manufacturer's (nVidia's) specification for the environmental conditions. Unfortunately, those bounds were apparently not tight enough, and the brittleness introduced by using the gold made it so the solder couldn't stand up to the vibrations of the running system. Diffusion was not the problem.

The problem in solder is not the lead. It's the tin.

Tin by itself forms whiskers spontaneously. Some of the worst culprits in this isn't the solder, it's the hardware - the tin in hardware used to mount PCBs etc seem to whisker the most and cause problems. And plenty of research have shown what combination of tin ("bright" tin is the worst - and it was only until recently did manufacturers stop using it) led to the worst problems.

Leaded solder suffers from whiskering as well. Anytime you use tin, you'll have whiskers. Its just a matter of time - use the wrong tin and it'll whisker quickly. Use the right tin and it'll whisker slowly. And it's not the result of electrochemistry, electromigration, or anything. It's just tin atoms wishing to migrate to relieve stress in the crystalline structure. They diffuse through the structure - the atoms aren't pulled locally, but from the entire bulk.

We knew this when the first solders were created for electronics. At the time, they experimented and found lead worked "well enough".They never went to find out if there's any other substitute. Massive amounts of R&D is going on in materials science to find alternatives.

Agreed. My previous camera (Canon SX20) had to be repaired twice, and then replaced (with an SX40), since it came from one of the first production lines which used leadless solder. The solder was bad, so the voltage converter would stop delivering the correct voltage after about 10 000 shots.

Quote from Wikipedia [wikipedia.org] :

Legislation published in July, 2011 removes these exemptions.

Apart from a few exemptions, RoHS2 covers all types of Electrical and Electronic Equipment (EEE) including some medical devices and monitoring and control equipment which have been exempt in the past. Previous exemptions to product from categories 8 and 9 will be gradually phased out,[16] with:[17]

- Cat. 8: Medical Devices - 3 years after publication
- Cat. 8: In-vitro-Diagnostics - 5 years after publication
- Cat. 9: Control and monitoring instruments - 3 years after publication
- Cat. 9: Industrial control and monitoring instruments - 6 years after publication

The reason stated on Wikipedia for exempting these things in the first place was being cautious until enough experience had been collected, considering that they only constituted only a small part of the electronics garbage pile anyway.

Solder, even in the "good old days" is not 100% lead. In electronics it can frequently be only 60-95% lead... and you know what the other portion mostly is? Tin. The problem of tin reacting with gold has nothing to do with lack of lead and can happen in both leaded and lead free solder.

Re:can someone please explain (3, Informative)

TapeCutter (624760) | about a year and a half ago | (#43178393)

Sorry but either your comprehension sucks or your just trolling. They are not "using tin instead of lead", it's an alloy composed of 63% Sn + 37% Pb, ie: good old fashioned tin-lead solder, the abnormally high trace levels of gold is the cause of the problem.

Re:can someone please explain (5, Interesting)

ebno-10db (1459097) | about a year and a half ago | (#43177225)

What's strange is how the gold got mixed into the solder. Long gone are the days of cheap gold when they would plate every metallic surface on a connector. Now they selectively plate the mating surfaces. Certainly they don't plate the part you solder. Gold contamination of solder is a well known phenomenon, but I haven't heard of it in decades, literally. The only other thing I can figure is that sometimes they flash plate some gold on the PC board to reduce solder whiskers or something. But that's a well known process. What the hell happened here?

Certainly they don't plate the part you solder

I worked as a surface mount process engineer on microprocessors, every connection that was soldered has gold as it prevents oxidation of the underlying metal. Not enough gold and you get oxides that are too thick or too difficult for your flux to remove and you wind up with unsoldered connections.
On the flip side too much gold and you start forming brittle intermetallics and changes in grain structure which will impact its reliability.

RTFM. Solder contaminated with gold is brittle. The article didn't specify where that happens, so can't comment if it is solder joint localized to solder down connectors or something else.

When I used to work in Telecom, we specify usually twice the amount of gold (30um) on connectors vs usual industrial application We do a lot of our own reliability test and manufacturers auditsetc on components and didn't have any issues.

Re:can someone please explain (4, Informative)

tibit (1762298) | about a year and a half ago | (#43176991)

I can only guess, but perhaps the coating on the terminals has to maintain certain mechanical properties over time. A wrongly formulated alloy, or a wrong thickness of plating will give you a connector that, perhaps, degrades in presence of heat and vibration. Or perhaps it plastically deforms on the contact area, thus lowering the contact pressure and eventually leading to loss of reliable connection. When you have small contact area, the contact pressure is sufficient to provide essentially a gas-tight connection. As the contact area grows, the pressure drops and eventually you expose your contact area to the atmosphere. At that point things usually go wrong.

Pure gold is soft and by itself it has about the worst properties imaginable for any sort of a connector surface. It literally rubs off, it's so soft. Its low resistance is irrelevant, since the gold layer is very thin. Gold's bulk conductance plays little role in overall resistance of a mated contact pair. You could replace gold with a metal that has 10x lower conductance, usually with little or no measurable change in contact resistance -- that is, if you can find something that can match gold in other properties (wetting of underlying surfaces, resistance to oxygen, etc.).

Gold is also useless as plating for high current terminals. I have designed plenty of connectors where some pins were for small signals and were gold plated, and others were for power and were silver plated. Gold plated power contacts simply lose the gold and then you have all the problems of an unplated contact pair that's exposed to the atmosphere since the gold erodes away leaving craters. It's no fun.

When you get relays with gold-plated contacts, there are often two sets of ratings. One is for low-current use, where the gold is guaranteed to stay on the contacts. Another rating is for sufficiently high current use where the gold is vaporized away and you're left with some other coating material that works well in this application. You can't swap such relays around without realizing what's going on, since contact pairs that were exposed to high currents will perform horribly in small signal, small current applications.

I also can't quite understand why people still buy gold jewelry -- all it took for me was a gold wedding band. I switched to tungsten carbide after a decade and I'm not looking back. The standard 18K alloy is a joke.

Re:can someone please explain (1)

ebno-10db (1459097) | about a year and a half ago | (#43177263)

But that still doesn't explain how the gold got into the solder. Connectors are selectively plated with gold only on the mating surfaces. It doesn't go on the part that gets soldered.

My guess would be this was a custom connector and either

1: some subcontractor decided that given low volumes it was cheaper to just plate the whole thing at the highest specified thickness than to work out how to selectively plate it (possibly in violation of a spec, possiblly following a spec that only specified minimum thickness of gold not maximum).
2: whoever was designing the connnector specified uniform gold plating

Alloys work in mysterious ways. Some alloys are "simple" having properties somewhere between the pure metals. Others have properties significantly different than their components. It can be a very non-linear process, in some cases even a fraction of a percent of "contamination" can drastically alter the properties of a metal, or you may have a "sweet spot" where the properties get better and better until you add just a little to much and change things completely. In this case someone said it was a matter of excess gold making the solder brittle.

Re:can someone please explain (2)

servognome (738846) | about a year and a half ago | (#43180705)

As you add more gold you are changing the properties of the alloy you are forming. A small layer of gold to prevent oxidation doesn't really cause much impact, your solder (in this case eutectic Sn-Pb) still melts and solidifies basically the same way. The more gold you add the more complex the system becomes. Rather than a nice eutectic material that goes from liquid to solid directly, you get different phases that solidify at different temperatures. This results in the formation of brittle intermetallics that fail prematurely.

Well... the thing's name is Titan; I'd say it probably out-did Monster in the gold contacts department. That said, maybe it couldn't handle the high bit-quality and kept getting distracted by being able to hear the imperfections from the original recording equipment....

I'm kind of amazed they couldn't spring for a full ATLAS system, I mean, TITAN, what losers.

We all came out to Oak Ridge,
and brought the cores online.
To make records with our petaflops,
We didn't have much time.
But there was a problem with the Mothers,
Were at the best place around,
But some stupid with a soder gun,
Burned the plans to the ground.
Gold in the soder, connectors gonna die .

Solder huh? (1)

Trogre (513942) | about a year and a half ago | (#43177365)

Just a question for anyone in the know, and I admit it is heavily loaded:

If lead was present in this solder, would the outcome have been any different?

Re:Solder huh? (0)

Anonymous Coward | about a year and a half ago | (#43177631)

no, it is the tin that is the problem, non ROHS solder is around ~63% tin

Re:Solder huh? (2)

TapeCutter (624760) | about a year and a half ago | (#43178535)

Oddly enough the solder they are using is 63%tin and 37% lead, the tin is not the "problem" since the problem doesn't occur without the extra trcaes of gold.

Re:Solder huh? (0)

Anonymous Coward | about a year and a half ago | (#43180603)

and gold is not the problem because it doesn't happen without the solder? Tin and gold don't mix well, there's tin in both ROSH and non-ROSH solder

interesting semlab report. I would have guessed that lead would have prevented the problem. I guessed wrongly.

Re:Solder huh? (2)

TapeCutter (624760) | about a year and a half ago | (#43178513)

There was lead in the solder, 37% to be exact.

Did you know that people in North America pronounce "solder" as "sodder"? I had no idea until I moved to the US and I still find it hilarious!

I did indeed know that, being from North America. However, I just learned that people elsewhere pronounce it differently. That's interesting. What, do you pronounce the L or something? Do you pronounce the L in "walk" too? Here "walk" and "wok" are basically homophones.

Uhhhh, you may now resume your regularly scheduled scheme to become jillionaires by mining computers for a few milligrams of gold.
