| Abstract: |
| The structure and machining process of thin-wall polysulfone attenna cover are introduced in this paper. The cause of cracking is determined by a series of experiments from different aspects, such as material, drilling parameter and heat treatment. Production shows that the reject fate is reduced from 30% to below 3% by optimizing drilling process parameters and heat treatment process. |
| Key words: polysulfone antenna cover cracking |
