摘　　要：为了提高弹载计算机的可测试性,采用MTM测试总线及BST技术对其PCB板进行重新设计,经重新设计后的弹载计算机系统具有良好的可测试性,可以及时、快速、准确地检测与隔离故障,缩短故障检测与隔离时间,进而减少维修时间,降低系统维护成本,提高可靠性。In order to raise the testability of missile onboard computer ,MTM test bus and BST technology is used to redesign it PCB board. The redesigned computer system has a good testability ,and can accomplish fault detection and isola‐tion timely ,fast and accurately ,shortening the time of fault detection and isolation ,and reducing the maintenance time and cost of the system ,and improving the reliability of the system.
