Application of Flying Probe Test in Quantity Production for T/R Cells of Phased Array Radar

数字板是T/R组件中的重要模块,决定了T/R组件的性能。数字板器件数量多、功能复杂,为其在线测试带来了挑战。飞针测试技术可靠性高,适用范围广,且发展迅速,是解决数字板在线测试瓶颈的有效手段。本文介绍了飞针工作原理,对飞针的测试程序开发进行了详细介绍,并对其中的关键问题进行了理论分析。现已将飞针测试成功应用于某批次T/R组件的批量生产中,统计结果表明,飞针测试技术对改善数字板在线测试效果显著。

As the most important module of T/R cell, digital board determines the performance of T/R cell. At present, in-circuit test of digital board is a big challenge in micro-electronics production due to its complex function and vast components. Flying probe test has a rapid development recently. According to its reliability and flexibility, flying probe test is used to solve difficult in-circuit test problems. This paper introduces the working theory of flying probe. Development of program design and some key technologies are deeply analyzed. Flying probe test has been applied in production of T/R cells and statistics show that the improvement is obvious.
