| Abstract: | According to the development requirements of aerospace products with high-speed integrated VPX architecture, the necessity analysis of VPX crimping connector selection, characteristics introduction, fisheye terminal structure design and reasonable PCB process scheme design were carried out, and the process control flow of high-speed integrated VPX architecture was completed. The PCB aperture size verification, connector contact impedance verification, connector test sample supplement 50 insertion and removal tests, structural prototype test verification and in-orbit application verification were carried out, and the results showed that: Based on the PCB process scheme and the process control flow of VPX architecture described in this paper, a high-speed integrated VPX architecture data transmission intelligent processing equipment has been successfully developed and applied in orbit, which fully verifies that the VPX crimping connector can meet the requirements of high reliability on board. In the future, the use of higher speed VPX crimping connectors, through a reasonable aerospace product process scheme, the development of higher speed and higher integration of aerospace products, to further improve the functional performance of products. |
