In recent years, with the rise of all kinds of intelligent terminal equipment, the quality requirements of electronic products are higher and higher. However, with the continuous influx of various fake and shoddy products into the market, it has an adverse impact on consumers and market reputation. Although the regulatory authorities and market electronic products continue to strengthen supervision, it is still impossible to avoid counterfeit goods. As the core component of electronic products, in order to ensure the quality of chips, manufacturers have adopted effective X-ray nondestructive testing technology for chip testing.

Chip detection is mainly to find out the factors affecting product quality in the production process as soon as possible and prevent the occurrence of batch out of tolerance, repair and scrap of chips. It is an important method of product process quality control. X-ray testing technology with internal perspective function for nondestructive testing is often used to detect various defects in chip packaging, such as layer peeling, burst, cavity and wire integrity. In addition, X-ray NDT can also check the possible defects in the PCB process, such as poor alignment or bridging open circuit, short circuit or abnormal connection, as well as detect the integrity of solder balls in the package. It can not only detect invisible solder joints, but also qualitatively and quantitatively analyze the detection results, so as to find the problem as soon as possible.

IC chip is one of the widely used products in the market, and its importance to products is self-evident. However, IC chips with realistic appearance and internal defects in the market can not be distinguished by the naked eye. Therefore, the emergence of X-ray detection technology makes up for this vacancy. In the process of chip detection, the X-ray detection technology introduced by domestic professional X-ray detection technology manufacturers can improve the chip detection efficiency. X-ray detection technology uses the X-ray transmitting tube to generate x-rays, which pass through the chip sample and generate a projection on the image receiver. Its high-definition imaging can be amplified by 1000 times, so as to show the internal structure of the chip more clearly, and provide an effective detection means for improving the "one-time pass rate" and striving for the goal of "zero defects".

Compared with traditional destructive physical analysis and fault analysis, X-ray has the advantages of timeliness, cost and professionalism. They have obvious advantages. In the face of those chips with very realistic appearance but defective internal structure on the market, it is obviously impossible to distinguish them by the naked eye. Only under the X-ray detection can they show the "original shape". Therefore, X-ray testing technology provides a sufficient guarantee for the product chip testing in the production process of electronic products and plays an important role.
