随着电子技术的飞速发展,对整机结构设计及内部互连的要求也越来越高了。但仍要遵循如下基本原则: ①便于实现总体要求, ②确保长期可靠性, ③满足装配、调试、使用、维护及外观上的要求, ④扩大系列化、积木化程度。便于实现系统的更换、组合、扩充或压缩;便于实现系统各级间的兼容性, ⑤便于实现机械化、自动化生产并满足各种工艺性方面的要求。如今,象电子计算机等大型电子设备的组装都已从组件、插件板、机櫃三级组装发
With the rapid development of electronic technology, the requirements for structural design and internal interconnection of the whole machine are also getting higher and higher. However, the following basic principles are still to be followed: (1) to achieve the overall requirements, (2) to ensure long-term reliability, (3) to meet the requirements of assembly, commissioning, operation, maintenance and appearance; (4) to extend the scope of serialization and building blocks. Easy to implement system replacement, combination, expansion or compression; easy to achieve the compatibility of all levels of the system, ⑤ easy to achieve mechanization, automation and production to meet a variety of technical requirements. Nowadays, the assembly of large-scale electronic devices such as electronic computers has been carried out from the assembly, the plug-in board, the cabinet three-level assembly
