Application of helium mass spectrometer leak detector for electronic packaging shell

Date:2024-07-15 Views:1245

Electronic packaging housings have high requirements for tightness, so helium mass spectrometer leak detectors are used to detect leaks in electronic packaging housings. The helium mass spectrometry leak detection method for electronic packaging housings has the following advantages: 1. High sensitivity: Helium is a small molecule that can diffuse rapidly and be accurately detected by a mass spectrometer, so it can detect tiny leaks.

2. High accuracy: As a detection device, the mass spectrometer has high precision and accuracy, and can accurately locate and determine the location and size of leak points.

3. High speed: It is easy to operate and has a fast detection speed, which can quickly obtain detection results and improve production efficiency.

4. Wide application range: It is suitable for various types of electronic device packaging housings, helping to ensure product tightness.

5. Non - destructive: Using helium as the detection gas will not damage the object being tested and maintains the integrity of the object.

These advantages make the helium mass spectrometry leak detection method for electronic packaging housings a common and effective leak detection method.

The main functions of electronic packaging housings are to install, fix, seal, protect chips, and enhance electrothermal performance. Electronic packaging housings play a crucial role in electronic devices. They not only protect chips from damage by the external environment, but also improve the reliability and performance of electronic devices by enhancing electrothermal performance and facilitating the assembly of the entire machine. In terms of the impact on the reliability of the circuit and the proportion of the circuit cost, the housing holds an important position. The requirement for tightness is extremely high. Once there is a leak in the housing packaging, the entire chip will fail!


Application of TO Package Helium Leak Detector

The materials used in electronic packaging are ceramics, glass, and metals. With the development needs of various electronic industries, packaging housings are widely used in military and civilian fields such as aerospace, aviation, navigation, radar, and communication.

Helium mass spectrometry leak detection uses helium to check for small holes in the packaging shells of electronic components. Because helium atoms are very small in size and can easily pass through small holes and enter the interior of the shell, this detection method can detect very small holes (that is, it can detect small holes with a leakage rate of approximately 1011~10-13 cm2/sec). Its sensitivity is comparable to that of radioactive leak detection methods, but it is simpler than radioactive leak detection methods.

Leak Detection for Semiconductor Ceramic Chip Packaging

The materials used in electronic packaging are ceramics, glass, and metals. With the development needs of various electronic industries, packaging housings are widely used in military and civilian fields such as aerospace, aviation, navigation, radar, and communication.

Helium mass spectrometry leak detection uses helium to check for small holes in the packaging shells of electronic components. Because helium atoms are very small in size and can easily pass through small holes and enter the interior of the shell, this detection method can detect very small holes (that is, it can detect small holes with a leakage rate of approximately 1011~10-13 cm2/sec). Its sensitivity is comparable to that of radioactive leak detection methods, but it is simpler than radioactive leak detection methods. Taking the metal packaging housing as an example, the back - pressure method of helium mass spectrometer leak detection requires leak testing of the tightness of the metal packaging housing itself. Since the packaged devices are small in size and cannot be evacuated or directly filled with helium, Nuoyi Technology recommends using the "back - pressure method" of the helium mass spectrometer leak detector for leak detection. The specific steps are as follows:

1. Place the packaged device to be tested in a vacuum pressure - holding tank. Set the pressure and time according to the size of the leak rate.

2. Take out the packaged housing and use air or nitrogen to purge the helium on the surface.

3. Place the packaging housing in a vacuum leak - detection tank, and connect the leak - detection tank to the inlet of the helium mass spectrometer leak detector.

4. Start the helium mass spectrometer leak detector. In the vacuum mode, set the leak rate value to 5×10-10 Pa•m3/s for leak detection.

5. Analyze the results: Judge whether there are leak points, as well as the location and size of the leaks based on the detection results.

This method is widely used in the electronics industry to ensure the tightness and stability of electronic devices.

The helium mass spectrometer leak detectors produced by Anhui Noy Technology have been widely used in many industries due to their excellent quality and stable performance, and can meet various applications. They can be used for single - machine leak detection or integrated into leak - detection systems or PLCs.
