The difference in chip color after opening the IC cover is one of the concerns of many consumers when purchasing electronic products. With the continuous expansion of the IC market, some unscrupulous individuals have also begun to use counterfeit and inferior ICs to seek huge profits. Therefore, how to quickly distinguish the authenticity of ICs has become an urgent issue. In this article, we will delve into the color issue of IC chips after opening the cover, and how to quickly distinguish authenticity to avoid being deceived.
We first need to understand the color issue of the IC chip cover opening. In the process of chip manufacturing, chip manufacturers generally use different materials, processes, and technologies to meet different application needs. These factors can affect the appearance, quality, and performance of IC chips. Therefore, even chips from the same manufacturer may have different colors.
Generally speaking, the chip color of the genuine IC is relatively bright, showing golden yellow or red. The chip color of counterfeit and inferior ICs is relatively dull, appearing brown or gray. In addition, the surface of genuine IC chips is smooth and free of obvious particles or impurities, while the surface of counterfeit and inferior IC chips has obvious particles or impurities.
In addition to the above methods, the authenticity of ICs can be distinguished through the following methods:
Visual inspection
The appearance of an IC is an important basis for determining its authenticity. Normally, the appearance of a genuine IC is relatively neat, free from impurities or stains, and the surface patterns and text are clear and clear. Counterfeit and inferior ICs often have a rough appearance, unclear patterns and text, and obvious wear and defects.
Measurement parameters
By measuring the parameters of the IC, it is possible to preliminarily determine its authenticity. For example, the parameters of genuine ICs are generally indicated in product manuals or labels, while counterfeit and inferior ICs may have inaccurate or missing parameters.
Shake
For some smaller ICs, they can be judged as genuine by shaking their bottles or boxes. Generally speaking, genuine ICs have high stability and will not become loose or loose when shaken, while counterfeit and inferior ICs are prone to becoming loose or falling off.
price
Price is also an important factor in determining the authenticity of an IC. Usually, the price of genuine ICs is relatively high, while the price of counterfeit and inferior ICs is lower. If you encounter an IC with an abnormally low price, it is likely to be a counterfeit or inferior IC.
Secondly, to avoid being deceived by counterfeit goods, you need to choose legitimate sales channels, inspect product packaging and labels, and use professional tools and equipment for inspection and analysis. For example, you can choose to purchase products from official channels or choose trusted sellers on large e-commerce platforms. You can also check the relevant information on the product packaging and labels, such as product model, batch number, etc.
The Color difference of IC chip cover opening is a normal phenomenon, but it should not be the only basis for you to distinguish the true from the false. To better distinguish authenticity, you can use a professional third-party testing agency. The company's testing services cover various testing projects such as electronic component testing and verification, IC authenticity identification, product design and material selection, failure analysis, functional testing, factory incoming material inspection, and tape weaving.
