Complete Automation of Manufacturing

The Kingston plant is completely automated through the assembly process. Workers don't really touch components again until the final Quality Assurance checks.

8-up DIMM blanks were machine loaded.

Then high speed chip inserters behind glass load memory chips in the blank PCB.

The filled PCB then passes through SMT-soldering stations that secure the surface mount chips to the PCB.

Quality Assurance is in play at every step of the process. At this point, the soldered DIMMs pass through an optical inspection station.

Every board and chip is automatically examined for integrity of the soldering. Poor or suspect products get dropped from the line for further testing.

    I have nothing against Kingston, in fact I have bought plenty of their ram before and I'll keep buying it in the future, but I won't believe that you test every module you sell by hand in a computer test.

    As for reliability, Kingston may be a bit more reliable as I've never had issues with their memory (compared to others) then again, Kingston is usually a bit less agressive with their timings than the competition.

    Typos, sheesh.

    ...binned down to *lesser* speed grades...

    ...when their *cache* is flawed...

    Heather, you imply that you have a rather high failure rate when you say that the cost of RMAs would be insane [if you shipped without screening everything].

    >>Any insight as to why failure rates would be so high?

    >>What happens with the failed product ... do they get binned down to less speed grades (not unlike how Pentiums get turned into Celerons when their cash is flawed)?

    >>How much margin do you give the memory? Meaning, if it's rated at PC3200, how much faster do you test it to ensure that it's not operating right at the edge of ability -- i.e. fail at PC3202?

    I know you likely cannot answer some of these questions, but anything you can offer is welcomed.

    Sorry to hear that. Would be intersted to know where you purchased these from.

    Testing DIMMs? Are those testers former Microsoft employees? I've had only 3 ValueDimms DDR400 CL2.5. Two of them were just broke, and the last wasn't able to run at DDR400.
    This "testing" is why I'll never buy again Kingston.

    i have to visit some friends in Taiwan this year. any links or review of non-trance/non-top 40 music nightclubs would be sincerely appreciated. thanks for the article. btw. really fun in light of Sunday + Monday Reply

    I run Kingston in my current system and after this article and Heather's post, I'll likely buy them again when I upgrade my rig in the coming weeks. Reply

    Hello - I can guarantee that the testing procedures done at Kingston are not B.S. I have worked at Kingston for over thirteen years and have never seen it done any other way. Yes, it does take a lot of time and effort, but it is worth it. Sometimes that does involved a slight premium, but we are very competitive in our prices. We don't want to have returns and value the quality that we have in our products. Sure, we could cut corners and make things easier, but the rate of Returned Merchandise would be insane and that price is a lot higher to pay.

    Some of our motherboard testing is done by hand depending on the quantity and some automated. We have an exceptional test engineering team who have patented many of Kingston's testers to make Kingston memory the utmost in quality.

    Again, I guarantee you that we don't just put on a show just because we have a visitor. I know that other manufacturers might do this, but it will come back to haunt them. We want to show people what we really do well.

    As far as Kingston being in the Enthusiast market - we are definitely there. We don't launch products until we find that they are not only just useful in the market, but can be done on the quality level that we expect and done not just for a handful of people, but to the market as a whole. Any company can come out with releases that show a higher, faster performing cards. But often speeds and performance are only validated on an engineering sampled board with beta bios etc. We want to make sure that outside of one board and one person that the masses reach these numbers. We launch products that aren't vaporware/paper launches. That is what makes us unique. It may look like we are behind sometimes in regards to speeds for enthusiasts, but we are definitely not. We just launch when we feel that it is useful to the market and we can reproduce more than just a handful.

    I welcome questions.

    - Thanks,
    Heather Skinner

    #15 & #18 - I have seen wave solder machines used for mixed motherboards with some SMT as well, but you are probably correct that the machines I saw were reflow soldering. I have changed the article to say "SMT-soldering stations" which should be a correct description in the absence of more info. Reply
