RFID Inlay and Embedded Key Fob and ISO Card Made for High Temperature & Reliability

FACTORS THAT DETERMINE RELIABILITY OF RFID INLAYS, CARDS AND KEYFOB
Properties & Attributes
AVANTE Patented Technologies
Traditional Methods and Technologies
1.       High temperature stability
§        High temperature propriety low cost substrate for long-term usage at 200°C and higher with intermittent processing stability of up to 300°C for minutes.
 
§        Etched copper for high temperature stability.
 
§        Soldered interconnections and encapsulated to protect from high temperature reflow.
§        Standard inlay substrates are polyester (PET) that deforms at temperature at 150-180°C and melt above 200°C and thus render them not applicable at higher than these temperatures,
§        Most have printed silver inks that will deformed along with substrate melting or deforms.
§        Most uses adhesive or mechanical attached that may be detached or loosened.
2.       Long-term Interconnection stability
§        AVANTE uses wired-bonded for its chip level interconnection and protected module for all its high temperature inlays. This proven interconnection ensures long-term stability at temperatures up to 300°C for long-term use.
§        The encapsulated module is soldered directly on etched copper for high temperature stability.
§        Soldered second level interconnections are encapsulated for processing at high temperatures beyond soldering temperature.
§        Traditional methods uses direct mechanical contacts on aluminum, metal strap or printed silver inks. These interconnections may suffer oxidation and/or mechanical contact loosening and thus lost in read distance or reliability.
§        The metal strap or direct flip-chip first level interconnections may or may not be encapsulated.
§        The metal straps are attached to the tag antennae with adhesive or mechanical compression that may loosen over temperature and/or mechanical stress.

The applications for RFID (based on ISO 15693 or ISO 18000-1/6) tags and RF-enabled (based on ISO 14443, ISO 15693 and ISO18000-6C) cards and key fob products are endless.

 
ISO 14443 For More Secured and Private Applications:

Key Fob and Cards based on ISO 14443 are shorter range in read distance for more secured and more suitable for the financial and security applications:

  • Access control:
    • Inside door
    • Building door
    • Passport or ID cards
  • Financial Transaction:
    • Retail check out programs
    • Pharmacy and drug dispensing programs
    • Loyalty programs with points accumulations
    • Kiosk access
    • And purchasing
    • Vending machine purchasing

 

ISO 15693 HF and ISO 18000-6C UHF For Longer Range Convenient Applications:

Key Fob and Cards based on ISO 15693 or UHF ISO 18000-6C have longer read distance for more convenience. The security can still be maintained high.

  • Access control:
    • Car Park
    • Gate
  • Monitoring and Convenience Applications:
    • Time attendance
    • Membership and activity monitoring programs
    • Identification and services
    • Frequent buyer or customer identifications
    • Library card and assets
    • Video and other rental membership
    • Gift cards and programs
    • Sports tickets and programs
