WIRELESS DEVICES DECORATED USING NON-CONDUCTIVE VACUUM METALLIZATION (NCVM) TECHNIQUES: CONSIDERATIONS AND COMMON FAILURE MODES
The Non-Conductive Vacuum Metallization (NCVM) process has become a mainstream metallization technology to achieve metallic like appearances on the surfaces of plastics used in wireless electronic devices while maintaining radio frequency (RF) functionality of the internal antennas. The impact on device performance and reliability of NCVM coatings has been discussed based on the most common failure modes and industrial testing standards. This paper discusses the effects of environmental conditions as well as construction variation of NCVM systems as they relate to various customer- impacting failure modes such as discoloration/corrosion, delamination and RF interference.
