NCVM (Non Conductive Vacuum Metallization)

* NCVM 目標是要鍍出具有金屬光澤且不導電,不會影響到無線通訊RF傳輸之薄膜.
* 利用鍍出金屬及絕緣化合物等薄膜,利用各相不連續之特性,得到最終外觀有金屬質感且不影響到無線通訊傳輸之成果.

(問題)請教一下,就我所知NCVM鍍層薄膜鍍材是錫,是用蒸鍍機鍍的,請問為何鍍成薄膜會不導電?台灣有哪家做NCVM的?

蒸鍍鈀材並非只有錫,各類適合產品表現的均為其可使用鈀材,
臺灣廠商:位速科技

謝謝指教,增長見識了,只是我試了鋁材不導電效果不佳

既然cnvm不导电，就有可能影响RF。那我们为什么要做导电膜层来达到emi，cnvm的原理和作用是什么，能否解答？

NCVM 不導電即不會遮蔽天線幅射,其作用並非EMI,而是純粹外觀上之需求金屬表現,但對RF不能有影響而採用此種製造製程.

請教一下屏蔽效應為什麼會讓RF不能通過呢?
雖然是做這一塊的但是還不清楚原理，麻煩您指導一下。謝謝！

Huang, I´d like to know how NCVM happens. It´s very strange to me that a surface is metallized and become non conductive. Could you explain to me, please. In English, because I don´t understand Chinese...:):):):):):):)...

請教一下，關於NCVM製程，通常主要的品質管控項目有那些?

是否所有的NCVM對各頻段的訊號都可通過?我用過一種不導電的電鍍但是仍會影響2.4MHz 的訊號,是否我用的不是NCVM?
