Apple iBook G4 Design Flaw Proven
empaler writes "Apple has long denied service on iBook G4s whose screens went black after just over one year of use, denying that there was any error. But now, the Danish National Consumer Agency has released a report proving that the error is due to a design flaw. So far, the only news site picking this up is The Register (unless you understand Danish). The Danish Consumer Complaints Board says that Apple needs to get a grip and acknowledge this error in the rest of the world. The NCA also has some photos from the report (explanations in Danish, but easily comprehensible from context)."
It is a feature. Next thing you know people will say the Ipod Batteries dying after a year is a design flaw too.

Reflow the solder. Simple.
Incidentally, with the introduction of RoHS-compliant lead-free solder, you will see this more and more. Consumer-grade lead-free is so crappy that it's almost impossible to make a single working board without at least some reflow work. Oddly enough, military- and medical-grade equipment are exempt from needing lead-free solder. Wonder why?
Perhaps people here are not acquainted with the product engineering process.
.. the less said the better.
Engineers take *every* component of a product into account during design, including the types of solder to be used and the methods of soldering to be employed.
Indeed, they may select higher quality solder in order to reduce the requirements and hence the cost of other parts, or they may specify lower quality solder in the knowledge that the rest of the components on their bill of materials can still be assembled to spec and will still work together reliably for the normal lifetime of the product.
In this particular case, either Apple engineers did not consider the effect of their design on the solder joint in question (it should probably have been a far more substantial joint), or they did not specify the right type of solder given the requirements of their design, or else the subcontractors who made the unit used a type of solder different to that specified by Apple. (In the latter case this would be an Apple testing/QA problem, since you *ALWAYS* check what your subcontractors are doing, no exception. If you value your brand name, that is.)
So whichever way you look at it, this is entirely Apple's fault. Design and/or testing engineers get paid for doing a good design and/or testing job, and in this case they haven't. Get the message to them, and they'll fix it --- engineers are always happy to fix problems, on principle.

There's a problem. Get it fixed.

Disclaimer: Both myself and one of my coworkers are IPC-610D certified inspectors of electronics. For those of you who aren't in the know, IPC-610 is the industry standard that dictates how all electronics assemblies are supposed to be put together. I spend considerable time inspecting fine pitch surface mount devices. I am also the manager of the assembly department at my company, where we make class-2 commercial grade electronics.
To say that I spend a lot of time looking at soldered joints is an understatement.
So, what's the problem here?
The Danish government is just as culpable as Apple is on this one.
The solder used in this joint is obviously (to me at least) a lead-free solder. (Lead free solders are exceptionally grainy and dull in appearance compared to leaded solder that is smooth and shiny.) The switch to lead-free solders was mandated to occur last year on July 1st by the European Union. Any electronics shipping into EU member nations must comply with this new standard, which is called RoHS, or "Reduction of Hazardous Substances". (Look it up in Wikipedia.)
Due to complexities in maintaining parallel manufacturing lines, most companies simply switched to the Lead-free solder for their entire product line. (As did my company). This means that most all new electronics you by are going to have lead-free solder holding them together.
So, why is this a problem? Plasticity.
Leaded solder alloys (SnPb 60/30) are extremely ductile. This means that they will flex a considerable amount before fracture occurs. With electronics that experience heat cycles, or any kind of motion at all, this is an extremely beneficial trait to have. Lead-Free solders on the other hand (like the most common SAC305 SnAu3%Cu0.5%) are incredibly brittle. What is obviously happening here is that the heat cycling from the laptop turning on and off is stressing this solder joint, and causing the joint to fail. Had this been leaded solder, I can almost guarantee that this problem wouldn't exist.
So what does this mean? Exactly what the electronics industry has feared. The EU made a dip$#!t move. Industry experts believe that the average lifespan of an electronic device has been significantly diminished. Down to an average consumer product lifespan of 5 years. There have been early reports of serious quality problems, including SWATCH having over 10,000 watches fail within a month of shipping. You can expect to see a drastic shortening of the lifespan of your electronic goodies. This is just the beginning people. If you see a device that is labeled as RoHS compliant, do not buy it if you expect to use it for more than a few years.
