| () |
| Abstract: |
| This paper describes the new sealing technology for the functional modules of the millimeter wave(MMW) front-end circuit.Soft soldering technology is used to seal the modules of the MMW T/R front-end to meet the sealing requirements through reasonably designing the connection structure of the soldering surface based on the characteristics of the connection surface and employing applicable temperature gradient and technological process, thus,a practical sealing technology which protects the MMW products against moisture,mould and salt mist is provided so that the products will be minimized,environment-resistant and reliable. |
| Key words: millimeter wave T/R front-end,assembly,sealing,anti-moisture,mould and salt mist |
