In past times several months, there has been a lot of press coverage surrounding the use of counterfeit digital components. This was further highlighted by the breakthrough of millions of fake components being found in US military products. Passive Components
Fake components are created by the following process; extensive removal, sanding, blacktopping and remarking followed by a detailed clean up of solder and the deal to make it look legitimate. These components cause a real threat to the industry as once in a system, are highly likely to are unsuccessful when being used. This kind of is the reason that the discovery of them in military products has hit the industry so hard. The united states military are implementing very tough methods to help illuminate these components and punish those distributing them.
Using a High Resolution Microscope is a sure way in which electronic component suppliers can find counterfeit components. This equipment can help reveal quality issues such as lead/ball alignment, ball height, part marking techniques, laser burn, sanding markings and solder flaws. By simply testing for these indicators a firm can determine whether a component has recently been legitimately made, or has been tampered with and resold (counterfeit).
A high resolution microscope including the Keyence VHX600 series is built to provide ultra-deep and high-definition remark. This equipment provides 3 DIMENSIONAL images which improve the level of depth a part can be seen in, multi-angle image resolution, real-time improvement and built in display. This superior technology allows an customer to view an element in a multitude of ways to ascertain its genuineness.
The microscope will be used to examine the markings on the components in a higher detail. Parts that are not phony should be completely flawless with precise and similar markings. Although some phony suppliers are incredibly skilled in hiding their work, many are lacking quality equipment to perform a good job.
If a part has a tiny hole in it, small enough that only a microscope could discover it, then this is an indication that the component has been interfered with. A counterfeit part would have been sanded down to scratch of any original laser white markings. This leaves the surface of the component very thin. When they then go to re-do the laser inscriptions the lazer can then occasional lose small holes through the component where it is so thin.
Different ways a supplier can screen electronic component quality include, X-ray, ED-XRF and Decap. One form of this testing can sometimes not be enough. A provider should have a wide variety of ways to check their components. In case you are about to use a new supplier or distributor of electronic components it is good practise to validate with them what quality assurance systems they have set up.
Companies who disregard counterfeits, ignore the huge potential for significant financial liability, and loss in reputation, if counterfeits penetrate to the production line.
Clever Electronics places quality at the forefront of all its businesses by consistently purchasing people, products and techniques. This permits us to take confidence in the distribution of real and high quality electronic components. It is essential that if looking to use a brand new supplier, that you ask them what systems and equipment that contain in location to ensure high quality components. If all suppliers and distributers start taking responsibility for the matters they handle as a market, we can help reduce how much counterfeit digital components considerably.
