Seektronics

In general, the system is always composed of multiple subsystems, which in turn are composed of smaller subsystems, until the subsystems are subdivided into a complex combination of resistors, capacitors, inductors, transistors, integrated circuits, mechanical parts, and other small components, any one of which will be the cause of the system failure. Therefore, the hardware reliability design should consider both the reliability design of a single control unit and the reliability design of the entire control system based on ensuring the reliability of the components.   1. Factors affecting hardware reliability   (1) Component failure.  There are three kinds of component failure: one is the defect of the component itself, such as silicon crack, air leakage, etc.; the second is the processing process, environmental conditions change to accelerate the failure of components and assemblies; the third is the process problems, such as poor welding, screening, etc.   (2) Improper design.  In
