The Impact of Production Environment on the Reliability of Power Supply Products
In the process of manufacturing, storage, transportation and assembly of components, due to the relative movement of instruments and equipment, materials and operators, electrostatic voltage may be generated due to friction, and when the device is in contact with these charged bodies, the charged bodies will be discharged through the device, causing the device to fail.
Most modern integrated circuits use MOS circuits, and most of the power modules also use MOS tubes and integrated circuit chips. In the production of power modules, if you do not pay attention to electrostatic protection, it often leads to a high component failure rate. Even if the product has passed the test, it may cause slight damage to the MOS tube and integrated circuit chip due to static electricity during the manufacturing process, which will affect the life and reliability of the power module. After the introduction of electrostatic protection system in the production environment (using human body anti-static grounding, floor anti-static grounding and anti-static grounding of operating devices and instruments, etc.), the damage caused to MOS tubes and integrated circuit chips can be effectively avoided. Anti-static damage of electronic components is a complex system engineering, which runs through the whole process of system or equipment development and production. From component procurement, packaging, transportation, inventory, installation, commissioning, testing to user use, the whole process, all-round, and all employees should follow a series of relevant measures to prevent static loss. Protection is a systematic project, which requires the investment of equipment, personnel, and effective management and system. It can be seen that the quality of an electrostatic protection system directly reflects the quality management level of an enterprise and is a demonstration of the strength of an enterprise.
