Guizhou University’s Functional Ceramics Laboratory and Guizhou Tuoyuan Sensitive Components Co., Ltd. have successfully reached a university-enterprise cooperation agreement.

On July 16, 2025, the Functional Ceramics Laboratory, led by Professor Zeng Fangfang, a specially appointed professor at Guizhou University, successfully established a university-enterprise partnership with Guizhou Tuoyuan Sensitive Components Co., Ltd. This collaboration leverages Guizhou University’s strengths in talent and scientific-technological resources, while drawing on Guizhou Tuoyuan Sensitive Components Co., Ltd.’s extensive experience in the production of sensitive electronic components. The two parties will focus on key technologies in the field of sensitive components, assemble expert teams to tackle “bottleneck” challenges, and carry out collaborative projects, technology transfer, and commercialization efforts related to sensitive electronic components. This partnership will not only promote the development of relevant disciplines at Guizhou University but also provide strong support for regional industrial development, fostering deep integration among industry, academia, and research, and contributing to high-quality economic growth in the local area.

Analysis of Various Common Faults and Their Causes in Electronic Components

In modern electronic devices, electronic components play a crucial and indispensable role. They not only support the various functions of the device but also directly influence its overall performance. However, under complex operating conditions, these components may face numerous challenges, including process-related issues during manufacturing and fluctuations in the external environment—both of which can lead to component failures. Next, we will delve into some common types of electronic component failures and their potential underlying causes.

How to efficiently diagnose electronic component failures?

Although electrical equipment contains a large number of electronic components, the failure phenomena exhibited by these components follow certain patterns. Among all components in electrical devices, resistors—being the most abundant—are not necessarily the ones with the highest failure rate. The most common type of resistor damage is open circuit; increases in resistance value are relatively rare, while decreases in resistance value are extremely uncommon. Among the various types of resistors, carbon-film resistors and metal-film resistors are widely used. The failure characteristics of these two types are as follows: First, resistors with low resistance values (below 100Ω) and high resistance values (above 100kΩ) are more likely to fail, whereas resistors with intermediate resistance values (such as several hundred ohms to tens of kiloohms) rarely fail. Second, when low-resistance resistors fail, they typically show signs of burning and discoloration, making their failure easily detectable; in contrast, failures in high-resistance resistors tend to be less noticeable. Wirewound resistors, commonly used for current limiting in high-current applications, have relatively low resistance values. When cylindrical wirewound resistors burn out, some may exhibit blackening, surface blistering, or cracking, while others may show no obvious signs of damage at all. Cement resistors, a subtype of wirewound resistors, may break upon burnout, but otherwise usually leave no visible traces of damage. As for fuse resistors, some may have a piece of their surface blown off upon burnout, while others show no obvious signs of damage—but under no circumstances will they exhibit signs of burning and discoloration. In summary, when inspecting resistors, one can use these characteristics to perform targeted screening, thereby quickly identifying damaged resistors.
