The Growing Threat of Counterfeit Electronic Components
Counterfeit electronic components:
- Lack authenticity
- Are falsely presented as real components, either in terms of their source or quality
- Have a significant impact on the entire supply chain, especially in Mainland China
- Affect various industries, including medical, automotive, consumer goods, networking, communication, space, and defense
Undetected counterfeit electronic components during production can lead to significant consequences. Failure, scrap, and rework rates rise, adversely affecting total profitability. In high-dependability applications, such as aerospace or medical equipment, the repercussions can be even more severe, putting lives at risk.
Common Counterfeiting Techniques
The cunning techniques used by counterfeiters make the detection of fake electronic components quite challenging. Some common counterfeiting techniques include blacktopping, remarking, and altering part numbers, which can be found in printed circuit boards. It is crucial to suspect counterfeit components to ensure the quality and functionality of the final product.
Blacktopping involves coating the area of a component, which can be removed by sanding or other methods to assign a new part number, often to deceive original component manufacturers (OCMs). Remarking is another deceptive practice, where markings on a component are altered to give the illusion that it is a different part, deceiving authorized distributors and customers. Similarly, altering part numbers is accomplished by modifying the markings on a component to give the impression that it is a different part, which can be detected during incoming inspection.
These techniques make it difficult to identify counterfeit components, requiring thorough inspection and testing methods.
Identifying Counterfeit Electronic Components
To detect counterfeit electronic components, including basic electronic components such as integrated circuits, various methods are employed, such as visual inspection, electrical testing, and X-ray inspection. These methods help detect discrepancies in part numbers, logos, markings, and other characteristics that can indicate the presence of counterfeit components, including counterfeit integrated circuit components.
The following subsections delve into the specifics of visual inspection, electrical testing, and X-ray inspection, highlighting their effectiveness in identifying counterfeit electronic components. A firm grasp of these techniques is vital to fight against counterfeit electronic components and affirm the authenticity of parts across different industries.
Visual Inspection
Visual inspection plays a crucial role in identifying counterfeit electronic components. During visual inspection, the following steps are taken:
- Verify part numbers against shipping documentation.
- Evaluate date codes based on previous data and past products acquired from the supplier.
- Check the texture of the top and bottom surfaces of a component. They should be consistent, as they are formed by the coating or molding of organic material.
- If the texture is dissimilar, the component is considered compromised.
Apart from verifying part numbers and date codes, tools such as electrostatic sensitive parts handling tools and a microscope with at least 30X magnification, complete with a built-in camera, are necessary for visual inspection. The MIL-STD-883 standard 3 is utilized to test the marking permanence of electronic components, and the scanning acoustic microscope is a non-destructive method to locate laser etching underneath blacktopping.
Electrical Testing
Electrical testing authenticates resistance, capacitance, and functional analysis of active parts, aiding in the detection of counterfeit electronic components. This method is essential for ensuring the proper functioning and authenticity of electronic components.
However, electrical testing comes with its own set of challenges. To test complex products, an expensive test setup and programming expertise are required, which is typically only available at Original Component Manufacturer (OCM) or certain third-party laboratories.
Despite its challenges, electrical testing remains a key tool in detecting counterfeit electronic components and verifying the reliability of parts across industries.
X-ray Inspection
X-ray inspection is employed to examine hidden or internal properties of electronic components, verifying:
- physical dimensions
- lead frames
- bond wires
- internal variations
This is done to ascertain defect-free products. One method for detecting counterfeit electronic components is by comparing physical dimensions with the specifications outlined in the datasheet.
Decapsulation and X-ray inspection are the most essential internal evaluations for detecting counterfeit electronic components. Tools such as a micrometer or other measuring instruments are used to assess the physical dimensions of a part. Additionally, an XRF Analyzer is utilized to ascertain whether the leads are composed of the appropriate material.
Tips for Avoiding Counterfeit Electronic Components
One of the most effective steps to evade counterfeit electronic components is sourcing parts from reliable vendors, substantially decreasing the chances of encountering counterfeits. Implementing in-house quality inspection systems helps to augment counterfeit electronics detection capabilities and curtail the utilization of low-quality parts.
Collaborating with external entities, such as reliable third-party companies that are forthright about their processes and adhere to ISO 9001:2008 standards for quality management systems, can also help prevent counterfeit components.
Obsolescence management, the practice of identifying outdated parts and proactively updating equipment accordingly, further mitigates the risk of counterfeit parts and increases equipment efficiency.
The Role of Industry Standards and Regulations
Industry standards and regulations are instrumental in curbing the circulation of counterfeit and substandard components in the electronic supply chain. The G-19 Counterfeit Electronic Components Committee, comprising representatives from all aspects of the supply chain, is dedicated to raising awareness and establishing industry standards to combat counterfeit and substandard products.
Standards such as AS5553 and AS6081 have been designed to mitigate the risks posed by the increasing prevalence of counterfeiting. Adherence to these standards and regulations helps companies to prevent the receipt and installation of counterfeit electronic parts.
With the continuous evolution of the electronics industry, the maintenance and updating of these standards become indispensable in the persistent battle against counterfeit electronic components.
