Intel is taking the next step in environmentally friendly products

Intel Corporation announced on Tuesday that the future of its microprocessors will be lead-free and environmentally friendly.  This follows a big tech industry shift towards products that are more environmentally friendly.  The shift will begin with its line of "green" 45-nanometer high-k metal gate (Hi-k) processors, which includes the next-generation Intel Core 2 Duo, Core 2 Quad and Xeon processors.

Lead is mainly used in a variety of micro-electric "packages" and "bumps" that attach the Intel chip to "packages", which are then wrapped around the chip and used to connect it to the motherboard.  Package designs include pin grid array, ball grid array, and land grid array, and will all be 100 percent lead-free.

With the introduction of 65nm Yonah, Chipworks -- a company that reverses engineers chip packaging -- discovered that Intel silently transitioned from lead-tin solder-ball interconnects to plated copper pillars. Since then, all 65nm Intel processors no longer use lead for interconnects.

"Intel is taking an aggressive stance toward environmental sustainability, from the elimination of lead and a focus on greater energy efficiency of our products to fewer air emissions and more water and materials recycling," said Nasser Grayeli, Intel vice president and director of assembly test technology development, Technology and Manufacturing Group.

Lead, which can cause neurological damage in humans if ingested, was used in electronics for decades due to its electrical and mechanical properties.  Intel produced its first lead-free flash memory product in 2002, and began shipping products with 95 percent less lead than previous chips in 2004.  The remaining 5 percent was replaced by a tin/silver/copper alloy in the first-level interconnect, the solder joint that connects the silicon die to the package substrate.

In February 2003, the European Union adopted the Restriction of Hazardous Substances Directive. The directive mandated that all electronics sold must be near lead-free by June 2006. Special clauses protected microprocessors from utilizing some lead in their design, but AMD and Intel both opted to go lead free before the call to action date anyway.

Production on the Intel lead-free 45 nanometer high-k processors, codenamed Penryn, will begin in the second half of this year.

Now read this-

I read sometime back the press release of-DFI for the following-

As I use a DFI mobo,naturally I began to scan the site for information for this Mobo(upgrade option).
I read/saw this warning at their site (below left)-

The solder used in some of these product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Now lets be honest does Intel as a matter of fact any of the hardware manufacturers,do display this warning !

Your explaination -
neurological damage in humans if ingested,
is not correct.

The DFI warning is the exact reason why Intel is worried about.
They can be taken to court by those ever/y MONEY hungry lawyers for damages.(class action lawsuit.)

While this has been widely published in California, it does not negate the fact that lead is still a neurotoxin.

Even in the studies that indicate a higher risk of birth defects, the lead must still be ingested by the parents -- which makes sense if you think about it. Make any parent ingest neurotoxins and I can assure you you'll witness higher birth defect rates.

That aside, the real reason Intel and AMD switched from lead was not because of lawsuit concerns. The amounts found in CPUs is too low to fall under violation of any of the ROHS or California clauses.

The real reason was electrical and manufacturing benefits.

Doesn't surprise me. I'm sure they would use an opportunity like this to spin it into something positive. To those who aren't sure how you get a toxin from a CPU into your body. The danger is surely when the old chips are dumped and these metals seep into the ground at land fill sites then potentially find their way into drinking water.

That ignores the fact that the lead was originally pulled from that ground in the first place. Lead is mined, not manufactured.

There are countless millions of gallons flowing over countless tons of lead ore even as we speak, courtesy of Mother Nature.

Nuclear waste isn't dangerous from the natural uranium found within it, but rather the large amount of daughter radionuclides which don't exist in nature. That's a far cry from disposing of lead identical to that found naturally within the ground.

And in any case, the dangers of radioactive waste disposal are drastically overstated as well. As long as any plutonium was first removed, nuclear waste could safely and easily be disposed of by simply dispersing it in the ocean. Emotionally, you might shy away from that solution, but given the vast amounts of radioactivity already naturally present in seawater, it wouldn't pose a threat to the environment or to human health.

It was sold as electronics solder in a specialized shop though, alongside German-made high end silver solder. In a packaging and diameter typical of electronics soldering. It was made by Chinese so it's entirely possible they purposefully resold plumbing solder as electronics solder. It would certainly explain extreme difficult I had working with it.

Antimony is as bad as lead if not worse. Since the focus has been on lead, companies have moved to other materials. Pure tin is also quite toxic. If I were you, I wouldn't use too much of that solder at a time.

As someone who did a lot of soldering I can say that leaded solder is indeed MUCH easier to work with. I only have used one type of lead-free solder but it was extremely difficult to use it, even with $150+ temperature controlled iron. The melting temperature is higher and it doesn't reflow - you cannot make the joint to melt after it's made even if you up the temperature; the only way I got it to melt again is by adding some leaded solder to it. I sincerely hope they came out with newer mixtures since, as the DIYers would be SOL if this is all we can work with.

Are we talking about electronics soldering here? Because as a jeweler I have a lot of silver solder around and have used it in a variety of applications even to solder wires together. It flows beautifully if you know how to use it. The only time I would need a lower melting point solder is if I couldn't use a high temperature torch around the item (such as a motherboard or something that couldn't handle the 1500° F required to melt soft silver solder)

I suspect it's a different solder. Silver solder does work beautifully and that's what I use when I can for audio electronics. It's only 4% silver though and it still has almost as much lead as the normal eutectic solder. The one I worked with is tin and antimony and masher2 pointed out it may actually be meant for plumbing (I shouldn't trust Chinese labels I guess).

I've noted that there are exceptions in the RoHS rules and those rules are used by a fair number of semiconductor manufacturers on many parts. I'm one who uses those parts in designs, not the designer of the parts -- but I've noted that in some packages it seems that a bit of lead is needed (having to do with the bonding I think). I've read some of the details but not being my thing, I don't recall more than the lead being needed as mentioned above. May not be a lead-tin sort of solder, may have to do with just being lead (which by itself has a fairly high melting point) and maybe something else. Lead being soft, perhaps it has to do with prevention of cracks . But it's something that they (semiconductor companies) have been trying to "fix" so that they can get rid of the lead so they don't need to use that RoHS exception clause -- but it's taking time, and it seems Intel is getting there.

Some have posted sarcastic comments about the press releases being dirty lousy fluff meant to sound good for purely promotional reasons. But to those folk (not you masher2), let me say that such things are important to circuit designers (such as myself) who need to make their product RoHS compliant and as lead free as possible. It's significant and important to people like me.

I think you're probably right about softness of lead. The most famous problem is of course the Xbox360 high failure rate which is regularly attributed to worse properties of lead free solder - specifically its rigidity. But as you mentioned, whatever you think about lead, you must comply with the law (or exclude a large customer base). I recall reading about the EU law and the consequences if you don't comply are onerous (read: jail time). And being a small business and claiming ignorance or small quantities or hobbyist or even being a foreigner does not absolve you. Even if you don't live in EU you'll end up traveling there sooner or later. And there's extradition too. Sure, they may not bother with small fry but you never know.

Yes, it's not about police as such, it's being able to sell products in Europe, and being RoHS compliant is one of those rules.

But it's also more than that as well, things will need to be RoHS compliant in the U.S. at some point too, writing is on the wall. Parts suppliers have been massively going over to RoHS compliance over the last few years. Some still don't, not 100% of the way there yet, but it'll probably be 100% within a few years (except probably for some legacy products where it'll get dropped before conversion).

If you lived in California, you would understand what that means. They have those signs in sushi and other restaurants serving fish. California passed an initiative a few years ago (could be more, nor sure) that mandates those signs be present anywhere there are chemicals that may cause cancer. Theres on outside Fry's Electronics, the doctors office, the local dump... etc etc etc. People here have just learned to ignore them (for better of worse). In the case of the sushi restaurants, it it referring to another heavy metal, mercury. If pencils still har real lead in them, your local Wallgreens would have to display the sign.

No, it's important to designer/builder of systems and boards that the components they use are lead free because their products are wanted to be lead free by their customers (in addition to RoHS rules if one wants to sell in Europe). Etc. Also there are complications in manufacturing where lead-free and leaded manufacturing lines have to be kept separate and so it's advantageous to being 100% lead-free. IOW it's advantageous to Intel's customers that their parts be lead-free (to Dell for instance, I'm not talking about a home builder). That they're getting the lead out is important economically to their immediate industrial customers.

"However, even though writing pencils made of graphite were first used around 1565, writing pencils that used lead were still in very common use in the 18th century. Why? Because they were cheaper, even if they were toxic. But, you certainly wouldn't want to suck on a "lead" pencil if it really had lead in it.

I'm pretty sure that's incorrect; I've read the exact opposite on dozens of occasions. Lead marking styluses were used until the 19th century...but they were simply a block of raw metal, not encased in wood or anything else, and not intended for writing, but simply general industrial marking applications. Some of the confusion may have come from the fact that, until the 18th century, graphite was actually thought to be a form of lead.

In any case, if you define "pencil" as some type of wood-encased writing tool, then they've always been made from graphite and/or slate.

Wrong. The first source of viable graphite was discovered in England, where the British refused to release any of the material to foreign nations or merchants until 1795. Lead was a far more common material. It wasn't until an alchemist ground finely a lower grade graphite and mixed it with a clay slurry that graphite was a financially feasible alternative to lead-core pencils. Graphite was originally thought to be an odd form of coal. Sheep herders discovered its marking utility on accident, as graphite was an excellent marker for their sheep, allowing them the distinguish them from neighboring flocks.
Its somehow become a myth that lead was never used in pencils.

You're wrong about graphite being originally thought to be coal. It was thought to be a form of lead ...hence it's original name plumbago (latin for "lead ore").

But you're still missing the primary point. Lead is harder than graphite and much less brittle, meaning there's no need to encase a lead marker in wood or anything else. Pencils-- if you define the term as a wood-encased writing tool-- were never made from lead. People marked with lead...but they didn't make pencils from it.

Also, though England did restrict access to their high-quality graphite, pencils were being made from powdered graphite as far back as the 1600s.

Anything that can be considered a free radical causes cancer, that is exactly what cancer is. Any atom that doesn't have a full outer shell of electrons causes cancer because it attaches to other atoms within a cell and then changes the cell.

They may have not phrased it that way.

But in any case all of these sarcastic retorts are IMO rather silly.

RoHS'ification (which includes six materials, one of which is lead) is something driven by the EU. You do it if you want to sell stuff there (or your customers want to sell stuff there).

That's what's driving the lead free campaign, and it's not just Intel, it's the entire electronics industry (along with other industries as well).

That said, the amount allowed is a lot more than zero so their part may already be RoHS compliant and they're taking it further, which is fine and good.

Good things are good things even if it isn't Mother Teresa doing it. Good things should be applauded rather than punished. Even if it's unusual, still should happen that way.

One may argue how big are the "bonus points" they earn doing it, because it may have happened "for free" when done for other reasons, but they still get bonus points -- just a matter of how many and how big the points are.

Lead free...

Lead in solder is quite stable and not likely to come out once the product is finished. Lead-free substitutes, on the other hand, use materials even more harmful to work with and dispose of. That's not to mention how much more difficult they are to use anyway. That's what happens when politics get in the way of science and engineering...
