某车载设备S波段T／R组件组装工艺

Assembly Process of S-band T/R Modules on Vehicle-borne Equipment

某车载设备S波段T／R组件工作频率较高，对组装的可靠性要求较高，本文从工艺准备、焊膏选择、网板设计、回流曲线确定、质量控制五个方面介绍T／R组件板的焊接及组件板与盒体装配的整个工艺过程，经过对组件的焊点质量检测及电性能测试验证了本文所采用的工艺满足需求。

S-band T/R modules on the vehicle-borne equipment work at some higher frequency and have higher need for reliability of assembly, so this paper introduces the entire craft process about the jointing of T/R mod- ule printed circuit boards and assembly with the box body from five aspects such as craft preparation, solder paste choice, halftone design, circumfluence curve confirmation and quality control. The adoptive craft in the paper is validated to meet the requirement by the quality detection of soldered joints and the test of the electrical properties.
