Anti Counterfeit IC Testing : Visual Inspection

As part of the Retronix Anti-Counterfeit IC testing service a customer approached us asking for our level 1 authenticity test, specifically the visual inspection service.

The customer send us approximately 3000 qty - NUD4700 type parts and asked to pick a random sample of 11 for visual inspection to check for authenticity. The reel information and datecodes given were the following:

    Where :
    M = Date Code
    MNH = Device Code
    . = Pb-Free Package

Anti-Counterfeit IC Tests

The first check straight away points out certain discrepancies.  Markings do not match the information on the datasheet, and the direction of the text with reference to the Anode was found to be incorrect, further inspection about the device itself revealed the following:

As it can be seen from the datasheet image and from the image that is sourced from Mouser Electronics, the bottom side of the device should be connected to the Cathode and continue onto the entire bottom side. But as can be seen with the image of the device on the right that these devices have two isolated pins with the bottom side being the outer casing and not a contact, this shows us that the device in question is not as per standard and is considered suspect.

Continuing investigation of the device for further inspection shows:

Device contacts are found to be incorrect, Anode and Cathode are formed into a gull wing as can be seen in 'Image 2' and not as they originally should have been as shown in 'Image 1'

Conclusion :

The visual inspection of the sample puts the batch as suspect and cannot be termed original as per standard datasheet and information available about the device. The report along with all photographic evidence and technical information was provided as a report to the customer as suspect counterfeit. This gives the customer a good insight into future purchases from the buyer and also this current purchase which could have caused big issues in case the customer would have gone on and implemented the same into his supply chain.
