Technical measures to enhance the reliability of PCB equipment: scheme selection, circuit design, circuit board design, structural design, component selection, production process, etc. The specific measures are as follows:
(1) Simplified scheme design:
When designing the scheme, it is important to ensure that the equipment meets technical and performance indicators while simplifying the design as much as possible. This includes simplifying the circuit and structural design to make each component as simple as possible. The use of popular modular design methods can also help improve equipment reliability. Modular design involves breaking down the system into modules with single functions, reducing design complexity, and standardizing the design process. Adopting a modular design approach has been proven to enhance equipment reliability.
(2) Utilize modules and standard components:
Modules and standard components have been extensively tested and proven to be reliable. By using these products, equipment defects and potential issues can be minimized, making it easier to replace or repair components when problems arise. Utilizing modules and standardized components not only improves equipment reliability but also shortens development cycles, making equipment modification and installation more efficient.
(3) Enhance integration:
Selecting large-scale and ultra-large-scale integrated circuits with high integration can help minimize the number of components, reducing potential risks. This not only improves equipment reliability but also accelerates the research and development process.
(4) Implement derating design:
Derating design involves operating components at stress levels lower than their rated capacity, reducing the failure rate. Parameters such as temperature and electrical characteristics are derated to enhance component reliability under various stress conditions. Different components require different considerations for derating, such as voltage range, current size, temperature, frequency, and vibration. Capacitors, resistors, inductors, power supplies, cables, connectors, and other devices should undergo derating in their design to improve reliability.
(5) Select high-quality devices:
The quality of components directly impacts equipment reliability. It is advisable to use industrial-grade or higher-quality products, preferably military-grade components, and conduct thorough aging screening before installation to eliminate early failure devices in military communication equipment.
(6) Maximize software resources:
Software programming offers flexibility that can be leveraged in design. Utilizing software resources can aid in fault location, problem identification, and expedited solutions. With a variety of debugging methods and tools available, utilizing software resources effectively is crucial in enhancing reliability.
