目前,国内通信设备都广泛采用条形机架结构,这是比较先进的一种结构形式。其所以先进,主要在于结构简单;占空尺寸小;安装灵活;三化程度高,采用它能够降低生产成本,缩短设计、试制周期。 条形机架的主要部件——电路功能框是安装电子元器件的主要结构,目前国内外对于电路功能框的结构设计和电路盘的安排,花样繁多,各有特色。对于这一结构和电路盘的设计合理与否,将直接影响到条架优越性的发挥,特别是集成化程度不高的电路盘,如果没有一个比较合理的设计安排,将会无谓的损失宝贵的空间。本文就电路功能框和电路盘的设计安 At present, the domestic communications equipment are widely used bar rack structure, which is a more advanced form of structure. Its advanced, mainly due to the simple structure; small footprint; installation flexibility; three high degree, using it to reduce production costs and shorten the design and trial cycle. The main part of the strip rack - the circuit function box is the main structure of the installation of electronic components, the current domestic and international structural design of the circuit box and the circuit board arrangement, a variety of tricks, each with its own characteristics. For this structure and circuit board design is reasonable or not, will have a direct impact on the superiority of the bar to play, especially the integration of the circuit board is not high, if not a more reasonable design, will be meaningless loss of valuable Space. This article on the circuit box and circuit board design safety
