Ultrasonic non-destructive testing is a non-destructive technique used to detect anomalies or defects in materials or structures. It uses the different propagation speeds of ultrasound in different materials and the changes in ultrasound when encountering abnormalities or defects to detect them. This article will discuss the principles of ultrasonic non-destructive testing and its applications in different fields.

Principles of Ultrasonic Non destructive Testing

Ultrasonic non-destructive testing is a material testing method based on the propagation characteristics of ultrasonic waves. The internal structure and state of a material can be determined based on the speed, reflection, and scattering of sound waves in the material, as well as the strength and frequency of sound waves. In ultrasonic non-destructive testing, ultrasonic probes are used to emit ultrasonic waves into the interior of the material, and then based on the reflection and propagation of ultrasonic waves inside the material, problems such as defects, cracks, and pores inside the material are determined.

Ultrasonic non-destructive testing applications

In the industrial field, ultrasonic non-destructive testing is widely used in castings, forgings, welded joints, eddy current testing, and other fields. For example, in casting inspection, ultrasonic non-destructive testing can detect whether there are surface and volume defects inside the casting, and determine the location and size of the defects, which is very important for ensuring the quality and safety of the product.

In the field of electronic product testing, ultrasonic non-destructive testing also has important applications:

1. Detection of the internal structure of semiconductor chips: In the production process of semiconductor chips, ultrasonic non-destructive testing can be used to detect defects and deformations in the internal structure of chips, such as gaps, impurities, and other issues. This is crucial for producing high-quality chips.

2. Cable testing: Ultrasonic non-destructive testing can be used to detect issues such as broken wires, short circuits, and damage inside cables. This can help cable manufacturers and users understand the status of cables and repair them in a timely manner.

3. Testing of electronic components: In electronic products, ultrasonic non-destructive testing can be used to detect the status and integrity of electronic components, such as rotors, piezoelectric sensors, resistors, etc. This helps to produce high-quality electronic products and reduce return rates.

4. PCB board testing: Ultrasonic non-destructive testing can be used to detect defects and poor connections on PCB boards and circuit boards. This helps to improve the reliability and durability of the circuit board.

The application of ultrasonic non-destructive testing in the field of electronic products can help enterprises improve product quality, reduce costs and risks, and further promote the development of the electronic industry.
