When it comes to microprocessors, the counterfeit ones are usually non functional - just an empty package. Making a functional micro is a huge amount of work. The chinese almost never do anything difficult if they can make a fast buck easily. The way you do it is you buy say 10k of some part from a disti. You then return it for a refund. But you return to them the duff parts. They put the duff ones into stock and somebody else ends up with them. By the time it is discovered the source of the duff ones is long gone, having made millions simply by running a chip overmoulding and marking machine. It is particularly nasty because the duff parts may be undiscovered for a long time, if your stock turnover is slow. So you can't claim under warranty because it may have expired. We used to always open the packages and program one device from each one. Unfortunately returning stock is not difficult, if you pick the right channel. |

OK, I've read through this thread as well as both Pdf's.I don't know, maybe I'm nieve but I find it mind boggling the amount of effort put in to fake items where amount of money made doesn't justifiy the amount of work put in.Just think about it. How many pcbs has to be stripped to build up a reasonable amount of ic' s to sand, sandblast, then to reprint whatever the hell it is they want to put on there. Not to mention the lead extensions. Just think about what needs to be done in order to achieve this at a scale where it becomes worthwhile. I don't think anyone in their right mind would dispute the major source of these faked parts which is kinda sad especially after reading all 32 pages of the "Trade war" thread. |

Well, everything is possible if you have unlimited amounts of virtually free labor. |
