[0002] Ball Grid Array (BGA) is widely used in core components of complex electronic products due to its high pin count, excellent thermal and electrical properties, long-term reliability and other advantages. It is the mainstream development trend of high-density and miniaturization of microelectronics.

[0003] In recent years, with the widespread application of phased array radars in fields such as drones and satellite communications, the core components of phased array radars using traditional brick-type design - transceiver components are becoming increasingly difficult to meet actual needs. Therefore, in order to meet the stringent requirements of drones and satellites for low cost, light weight, low cost and high reliability, transceiver components based on BGA packaging technology are gaining more and more attention in the industry.

[0004] However, due to the miniaturization of BGA packaged transceiver components and the rapid increase in the number of component channels in radars, traditional manual assisted test fixtures for component index testing have problems such as inconvenient manual picking and placing, low efficiency, and easy damage to components. At the same time, in order to ensure the high reliability of radar transceiver components, multiple rounds of electrical testing are required before and after the component is capped. The number of test indicators is complex, the amount of data is huge, and many types of instruments are involved, which further increases the difficulty of the testing work and ultimately brings new challenges to the efficient and accurate testing of BGA packaged transceiver components.
