Disposal of counterfeit SMT patch components

Disposal of counterfeit SMT patch components
According to an artICle published by Le Monde in 2016, the total turnover of SMT electronic components in 2015 ranked 7th, 309 billion euros, which is equivalent to 10% between - 21 billion euros and 30 billion euros From destroying computers to destroying the integrity of complex systems (which cost millions of euros), these illegal copies pose a major risk to the entire industry
In order to deal with this increasingly serious phenomenon, researchers and manufacturers must compete with traffickers, play a creative role, and find new combat strategies.
The illegal copy MARKet is booming
At least one of every two home appliance crystal companies has to deal with counterfeit products of its technology. It is said that the number of copies in circulation has increased three times since 2009. Aircraft manufacturers have determined that the counterfeit electronic circuits they supply appear real, but are actually empty. In 2010, the US military took the lead in condemning this wave of illegal elements. The damaged parts damaged the infrared vision system of the helicopter, the deicing system of the patrol aircraft or the flight display of the transport aircraft.

Computer USB keys were the topic of discussion in 2016. The device is equipped with a DC-DC converter and a capacitor, which are responsible for the connection of sending garbage to the landfill, thus damaging the components of the PC. A hong kong company copied the key and sold it to the it security consultant for official use.
SMT electronic component failure. There are several obvious reasons:
*Injury and fatal hazards in certain sectors (medical, military, automotive)
*Risk of fire in case of short circuit
*Efficiency of modified products
*The huge cost and loss of revenue in the SMT industry
To copy components, counterfeiters use various technologies. They can obtain blueprints of electronIC components through various eSPIonage activities or reverse engineering to discover their secrets.
Why are counterfeit products flooding the market
The media often talk about counterfeiting in the luxury goods industry, but all industries are more or less affected by scale, and the security risks vary from product to product. Unlike the luxury goods industry, no fault is allowed in the military, aviation, automobile or medical industries.
There are many reasons to develop stolen electronic components:
Globalization has greatly reduced the cost of acquiring technology
Production outsourcing in Asia promotes technology transfer
The interoperability of operating systems in IT allows large-scale dissEMInation of information
This shipping giant has adjusted its products to make SMAll package transportation more affordable
Counterfeiting also comes from the production of e-waste sent by developed countries to developing countries. The counterfeiters use these wastes as raw materials to obtain illegal copies of spare parts.
Technologies used by illegal manufacturers: non functional equipment, sandblasting and observation, black paint, replacement of equipment, use of waste products, forged labels, etc.
Counterfeiting: control components
Check components
The first thing to do is to conduct a series of tests and controls on SMT electronic components to ensure their integrity (AOI test, power, impedance, metallographic cutting or X-ray).
The X-ray machine can accurately and non-invasive inspect the mold, weld and delamination. Then, SIMply compare the manufacturer's specifications to verify the authenticity of the components. According to the same logic, the tolerance provided by the electrical test of the suspect component is sufficient to compare with the manufacturer's data. If the gap is too large, a more in-depth investigation should be carried out.
If the height, length and width are measured and compared with the manufacturer's specifications, the height, length and width can also be inferred if the components are relative.
Find Break
The method often used by counterfeiters to cover up black spots is to hide the original serial number and reprint another mark on the top to mislead buyers. The naked eye cannot detect fraud, but a skilLED eye can detect fraud under a microscope. Acetone can also be used to remove incorrect markings.
Unblock
In the final analysis, the disassembled parts are invasive and destructive. However, when all other tests fail to ensure compliance, this process is still the final solution for viewing your ingredients. Use a powerful microscope to check the authenticity of the manufacturer's trademark, defective parts, layout and serial number.
Prevention of counterfeiting
Directly from SMT manufacturer
Direct supply to manufacturers seems to be a reliable solution to minimize risk. The addition of intermediaries reduces transparency and increases risks.
