摘　　要：鉴于航空电子产品具有小批量、多品种的特点,飞针式ICT测试是其最合适的在线测试方案。针对飞针式ICT测试过程中多种测试模式重复测试且测试时间长的问题,提出一种新的基于非向量测试技术的测试解决方案,试验结果表明,新方法在不降低测试覆盖率的同时能缩短40%以上的测试时间,极大地提高了飞针测试的速度,缩短了测试周期,保障了航空电子产品的及时交付。Avionics products feature small batch and multi-species, therefore flying probe test is a more appropriate online test solution. A new solution based on vectorless test technology is proposed to solve the problem of the time-consuming testing process. The test results show that the new method can keep test coverage while reducing test time by more than 40%, which greatly improves the speed of flying probe testing and shortens test cycles to ensure the timely delivery of avionics products.
