| 摘要 |
A sealed filter member comprises a filter body means having selected first and second surface portions, the first surface portions defining discontinuities between and surrounding the second surface portions; a dielectric polymerizable material polymerized on and adhered to the selected first surface portions defining sealed surface portions and plating material disposed on the second surface portions defining plated surface portions. The plated surface portions comprise electrically discontinuous electrode means. The polymerized dielectric material both excludes plating material from the sealed surface portions during plating and permanently seals the filter body means at the sealed surface portions. The polymerized dielectric material is resistant to solder and solvents and excludes solder and solvents from the sealed surface portions. A process for making the sealed filter members is also disclosed. |
