Apple iBook G4 Design Flaw Proven 252

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)."

    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?

      Exactly... It's NOT a design flaw; low quality solder joints are a manufacturing defect. As systems heat up and cool down, joints expand and contract, and can lead to cracked joints. The lower the quality the solder joint, the sooner it will happen.

        It's an engineering defect. Whether you look at it as a design problem or a manufacturing problem depends on the constraints (and perhaps also on your point of view). If they are constrained to use particular materials, then the design needs to be such that the system, when made of those materials, doesn't fail prematurely.

        Understanding the constraints and setting specific definitions around terms like "prematurely" contribute inputs to the engineering process. In the end, if you release a product that breaks too soon, you messed something up and have a defect.

        All of which is fine, if you then respond by revising either the design or the manufacturing process and fixing people's broken computers, which is not what Apple has tried to do.

          And all Macs come with a one-year warranty against manufacturing defects. Any other measure of "too soon" is just personal opinion. I expect that Apple repaired all iBooks that failed within the warranty period. Apple makes no statements on the useful life of their products beyond their warranty statement, AFAIK.

          All of which is fine, if you then respond by revising either the design or the manufacturing process and fixing people's broken computers, which is not what Apple has tried to do.

          Got any proof of that wild accusation? Remember, Apple contracts board manufacturing to third parties. I doubt that Apple has sit idly by and done nothing, but that doesn't mean that Apple would have been successful in anything they tried either. Sometimes technique changes (like lead-free solder) give some manufacturers headaches.

          Besides, have you heard about this issue on the new MacBook or MacBook Pro systems, which have been in the market over a year now? Seems like Apple had some improvements made, then, if bad solder joints were the root cause of the iBook issues.

          • So you should just expect if you buy an iBook that you will have to replace it shortly after a year. Just like when you bought an iPod and had to have the battery replaced after a year...

              That does look like a manufacturing defect, but it's not common. I have worked on hundreds of macs this year and I have only seen maybe one or two ibook G4s that had dead displays. It's not anywhere near the scale that I would say deserves a recall. If every 1 unit in 200 is bad, the model is not defective. Now if we are talking 1 in 10 maybe we can start saying there is a problem.

        I guess lead in solder gives the joint a little flexibility and tolerates expansion and contraction cycles.

        I miss the good old days where you can find a bad part by following the burnt wiring harness right up to it. My current favorite is the chip that overheats, unsolders itself and falls off the board.

      You don't even need to solder. Just disassemble the iBook (challenging enough!) and put some sort of filler on top of the graphics chip. I used a 3M rubber foot. Close everything up and the bottom of the case will keep the chip in place. I haven't had a problem in the 6 months I did this repair, and have continued to tote my iBook all over on my scooter.

      That said, it's clearly a design defect, and should have been fixed by Apple just like the G3 iBook.

      Perhaps people here are not acquainted with the product engineering process.

      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.

      As for Steve Jobs and Apple Customer Services .. the less said the better.

      There's a problem. Get it fixed.

        What do you know about electronics manufacturing? 1. "Higher Quality Solder" There is no such thing as "higher quality Solder". There are two industry recognized solder alloys out there. SnPb 60/40 and SAC305. SAC305 is used on RoHS compliant assemblies, and is mandated by the EU. From the photos, it is obvious to me that this solder was SAC305. (Yes, I can tell. From the side-cuts, you can see that the solder is very grainy and dull. This is the hallmark of lead-free solders.) Again, due to the idiotic RoHS legislation, manufacturers are REQUIRED to use a lead-free alternative, among which the SAC305 is the best. (The proverbial winner of the special-Olympics.) 2. "A far more substantial joint". The solder joint in the photos EXCEEDED IPC610-D Standards for even Class 3 medical devices. This is a SURFACE MOUNT DEVICE, and as such, there is no other way that you can get a more "substantial" joint, unless you went to a TH DIP package, if it was even available, and if you could even fit it into the design. 3. "Right type of solder" See number 1. 4. So no, it is NOT entirely Apple's fault. I'd bet $100 that if this chip were removed, and a new one were installed with SnPb solder, then it would not fail. Period. But since Apple isn't allowed to use the right solder, this happened. Have you ever designed something? Can you say that you tested EVERY POSSIBLE point of failure? No, didn't think so. It's because it's impossible to do. There is a problem, and it's the knee-jerk reaction of the EU to blindly ban the one substance that has been fully responsible for allowing the computer revolution to occur. Way to go!

          So... an engineer is told to design a ship. He's told that the material to be used is wood, but designs it as if it were to be made of steel (because that's the right material!). The ship fails. How is it not the engineer's fault for not designing the system to the intended specifications? If the specs said that a non-lead solder was to be used, then the board should have been designed so that it would not fail with a non-lead solder.

          Maybe they swapped out the solder after the design was finalized and it's not the designing engineer's fault. But you can't blame the failure on the solder (unless it was not the correct composition). It's not as if this lead-free solder is some mysterious substance. Someone, somewhere along the line, failed in the design of this system.

    • The affected chip is one that normally gets quite hot in normal use-- the thermal stresses built up and mechanically failed the joint.
    • The chip is on a part of the PC board that flexes under normal or abnormal use. The joint flexed a few times and finally failed.
    • The board was improperly wave-soldered-- either too low
  • ...and it was so expensive to fix, I bought another (used) iBook. With Applecare. And of course, this machine had a similar (if not exactly the same) problem about eight months after I got it. Thank God for Applecare.
  • The lab report (in english) can be found here [forbrug.dk]
  • ...it were a Toshiba 4600.

    (Insert -1 Flamebait here).

    I have an old Toshiba Satellite Pro 4600 that originally came with Windows 98. It then ran Windows 2000 and now runs Windows XP. Can an iBook of the same era even run OS. =)~

  • I've been out of a laptop since less than a year after I bought it. Apple refused to fix my G4 iBook after sending it to them twice. It's now more than two years old (maybe three?). If they fix the one I have it is old technology and pretty much useless to me now anyway. Are they required to refund my purchase? Or replace it with modern comparable equipment? Even a fully functioning G4 iBook is pretty crappy by today's standards.

    We love Apple for their design flaws, don't we!!

    The SE/30 featured an shielding cardboard that was coated with metal on the bottom; the motherboards pins would at time poke through, and if the machine was sitting vertically for a while, suddenly it could go - blam - and stop working and go into some type of hangup or crash. For two models, I could repeatedly get them going by shaking the machines upside down, but neither Apple, nor Apple dealers, acknowledged the issue. It may be that having parts installed - and having people disassemble and reassemble parts of the Mac - may have played a role.

    All of the compact Macs featured floppy disk drives that, over a working period over more than 6 hours, would reliably and predictably cause floppy disk errors. So I'd start using a new OS floppy after 5 hours, and things would be o.k., or not do it and consistently get crashes from 7 hours on upwards. They had built in a bright CRT, and obviously, shielding was some issue there. Nevertheless, this was an obvious design flaw.

    Or the iPod mini. The iPod mini featured some weird shielding problem whereas crackling noise would occur. It would disappear as soon as the components that are stuffed together (battery, main board, micro disk) were pulled from each other - then, no crackling noise would occur even when mechanically straining the 3.5mm jack. Another design problem where capacitor- and shielding-related issues determined the outcome.

    Or, take the Powerbook G4 Aluminium "Narcolepsy" model Apple built and sold! A design flaw classic. Not admitted by Apple, ever. I guess they switched to Intel partly because there were so MANY of these sold, that switching to Intel may have been the only way to give the Powerbook G4 owners a good reason to buy a new Apple laptop rather than attempting to force Apple to fix their old one. Maybe one day, we will hear the insider story of that botched up piece of hardware?

    Also, there were a number of Powermac G5 computers that all had severe logic board problems that I laid hands on - two of them DOA (Dead On Arrival), and on another one I just got it repaired for the cheap sum of around 800 dollars.

    So, I think if anything is newsworthy it'd be publishing that Apple actually managed to assemble some parts without design problem. That'd be what Slashdot may want to focus on, not that Apple "yet again" was shown to have screwed up something we all knew they couldn't get right to begin with.

    Anyone believe that they can get the iPhone right, at all?

    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.

The study of non-linear physics is like the study of non-elephant biology.
