Reliability refers to the ability of a system, mechanical equipment or component to perform its intended function under specified working conditions and over a set period of time. In military standards, reliability is defined as the probability of completing a specified function under specified conditions and within a certain timeframe. It is an important indicator for measuring the level of reliability.
Reliability is influenced by multiple factors, including product design, manufacturing processes, environment, and usage conditions.
The three main types of reliability are:
Inherent reliability
Inherent reliability refers to the reliability of a product at the design and manufacturing stage. For electronic components, factors such as raw material quality, manufacturing processes, and operating parameters can all affect inherent reliability. For electronic products, inherent reliability is influenced by factors such as product complexity, circuit and component selection, working parameters and reliability, mechanical structure, and manufacturing processes. Generally, the more complex the circuit and structure, the more components used, and the more manufacturing processes involved, the lower the inherent reliability of the product.
Usage reliability
Usage reliability refers to the impact of users and maintenance personnel on product reliability. It includes whether the usage and maintenance procedures are correct, whether the equipment selected is reasonable, whether the operation methods are proper, and other human factors. Usage reliability depends largely on the user of the equipment. Skilled and correct operation, timely maintenance and upkeep can significantly improve the usage reliability of the product. Usage reliability is directly related to human-machine engineering design.
Environmental adaptability
Environmental adaptability refers to the impact of environmental conditions on product reliability, including natural, mechanical, and electromagnetic environments. To improve the environmental adaptability of equipment, various effective protection measures need to be taken.
Reliability is an important aspect of product quality. Generally, a good product quality means that it not only meets the expected technical indicators but is also reliable in use. Reliability directly affects the product's performance, customer experience, and satisfaction. In military, navigation, communication, aerospace and other fields, reliability is one of the core indicators that users are most concerned about.
When evaluating an electronic product, we look at whether the function is advanced, and the appearance is beautiful - these are the core issues that designers focus on. We also look at whether the product can be efficiently and inexpensively manufactured - this is the focus of manufacturers. Finally, we look at whether the quality is stable and the product is reliable - this is the concern of users and represents the level of product design, as well as an important embodiment of enterprise core competitiveness.
With the continuous development of material technology, component technology and electronic design technology, electronic products are becoming increasingly complex, and integration is becoming higher. This places higher demands on electronics reliability. The improvement of product reliability to achieve optimal performance is a key factor in improving product quality and directly affects user evaluation. Improving the reliability of electronic products is an extremely important and challenging task. From a certain point of view, improving product reliability also improves the product's core competitiveness, and the embodiment of technological progress is the upgrading of product quality and the improvement of reliability.
