A flip chip interconnect is made by mating the interconnect bump directly onto a lead, rather than onto a capture pad. The method includes: in the process of generating the software installation package, a plurality of support library files required to develop the software are divided according to file types, and the support library files of the same type are compressed together, and the compressed support library files of the same type are located in the same one part of the software installation package. The method also includes determining if the output signals are outside of a range of output signals. As the distance increases, the display can be modified to include a zoomed-out view of the object. A rotational shaft operably coupling a carrier of the composite planetary transmission section with the output rotational body is inserted through a planetary transmission mechanism of the composite planetary transmission section, the first clutch mechanism, the second clutch mechanism and the speed-reducing planetary transmission mechanism. The riser reactor system prevents riser reactors with a plurality of inlet ports for feeding gases having different compositions and for controlling the residence time of a gas catalyst within the riser reactor.
