What are the advantages of a cryogenic probe station? How stable is it?

Nowadays, more and more corporate culture began to vigorously carry out the analysis of product technology research and development, because the Chinese market information is updated very quickly, only to ensure that the company's products have a certain advantage in the market, in order to effectively avoid being eliminated. With the continuous innovation and development of the probe table process, there are now many types of probe tables.

1. Meet various temperature requirements (very low temperature)

When testing wafers at low atmospheric temperatures, water vapor in the air will condense on the wafers, resulting in excessive leakage or the probe not being able to contact the electrode, leading to test failure. To avoid these problems, it is necessary to remove the water vapor from the vacuum chamber prior to the test and keep the pump running throughout the test.

Oxidation is more pronounced when wafers are heated to temperatures of 300 °C, 400 °C, 500 °C or higher, and the higher the temperature, the more severe the oxidation. Excessive oxidation can lead to electrical errors, physical deformation and mechanical deformation of the wafer. To avoid these problems, it is necessary to pump oxygen out of the vacuum chamber prior to testing and to keep the pump running throughout the test.

During wafer testing, due to the phenomenon of thermal expansion and contraction, there will be relative displacement between the positioned probe and the device electrodes, so it is necessary to reposition the needle holder. the CINDBEST needle holder is located outside the cavity, we can also choose to use the operating lever-controlled automatic needle holder to adjust the probe position.

2. Small size and high stability

Compared with the traditional probe station, the high and low temperature vacuum probe station is more stable. The use of Chinese advanced technology for technology, so that the probe table in the work of the development process of fluency and smoothness is higher, which can ensure the stability of each experimental research data. So that an experimental analysis of the results we will become more accurate, for the economy of China's enterprises to quickly research and development of new products have a great help.

3. Lower cost, compatible with DC and RF test applications

Compared with the traditional probe table, this probe table uses advanced synthetic materials, the cost is lower than the traditional probe table. But the functionality and accuracy are more powerful, so it is normal that the sales are booming.

To summarize, the main reason for the sale of high and low temperature vacuum probe station is because of the affordable price, so that many companies see the benefits. But low prices by themselves do not guarantee that the boom will continue. Sales are up because the probes are more powerful and can meet the needs of any business.
