Integrated chips are modern digital integrated chips manufactured mainly using CMOS public interest. CMOS devices have very low static power consumption, but in the case of high-speed switching, CMOS devices require power supplies to provide instantaneous power, high-speed CMOS devices have dynamic power requirements exceeding those of similar bipolar devices. Due to the multi-channel supply market of electronic components in China, the authenticity of integrated circuit chips is a problem for many electronic enterprises and electronic engineers and technicians, so what are the identification methods of integrated chips?
Here we share three ways to identify the authenticity of integrated circuit chip devices, I hope to help you.
1, through the pin identification
The original factory chip pins are neatly arranged, and after the renovation of the chip pins are generally not neatly arranged. Can also be viewed through the chip pins, the original chip pins are almost all silver gray, and the colour distribution is very uniform, while the counterfeit pin colour is very bright.
2、Identify by imprint
The original chip mark is printed by a regular machine, and the font is very clear and correct, and is printed very evenly on the chip. However, the markings of counterfeit products are defective, and some will have a slightly tilted font.
3、Identification by positioning mark
The main function of the positioning mark is to find the front and back side of the chip during the soldering process. At the same time, the number one pin of the chip can be found. The depth of the positioning mark of the chip is indeed consistent, but the points of counterfeit or refurbished chips will be shallow due to polishing, and the depth of each product will be different.
Promotional reading: The role of the integrated chip
A good integrated chip can enhance the entire performance of this product. The integrated chip is the soul in the appliance, able to process instructions, perform operations, control time and process data.
The role of the integrated chip is also to complete arithmetic, processing tasks. There are integrated chips with complex functions and those with simple functions. It can be said that without chips, our products would not be miniaturised and their functions would not be complex.
