Abstract: The test curve distortion will occur when the BGA package micromodule is tested with high efficiency and no damage using the crimping probe connector. Simulation analysis is made to search on the reason of the poor performance of the test system composed of "micro-module-test mould- test board" caused by the introduction of test mould. The influence of parameters such as permittivity, limit spacing and limit gap on the radio frequency (RF) transmission performance of the system is analyzed in detail. It is found that the changes of the permittivity and limit gap have great influence on the performance of the system. The limit spacing has a negligible effect on the system.
