| Abstract: |
| Some antenna-fee
der devices have too complicated structure or too tiny narrow path to be
protected by traditional plating process. According to above characters,vacuum v
apor deposition process for Parylene method is proposed.
Silane process is used to improve the adhesion between Parylene film and the b
ase. The deposition process is investigated to increase the film quality.
The processed chamber has passed the anti-corrosion and EM test. |
