For a certain shipborne module in-stallation space and weight are limited strictly , printed circuit board to shield with each other and the three proofing requirements ,the structure de-sign is developed ,and its thinking of design and de-tailed implementation are introduced in this paper . T he engineering applications demonstrate that the volume and weight of the module is reduced effec-tively by the chamber design ,slot and the reinfor-cing rib structure ,and electromagnetic shielding is achieved .The good protection ability under harsh marine environment is obtained by choosing mate-rial ,corrosion parts surface treatment ,printed cir-cuit board protection and anti corrosion sealing desig n .
