The market for Dual Interface cards (DI cards) is booming, especially for payment and identity cards. DI cards require a reliable connection between the antenna and the chip module. For DI card assembly processes, we offer tesa® ACF 8414, an anisotropic conductive hotmelt film that can be adapted to common assembly lines without investments. Mechanically embedding the module and electrically contacting the antenna are now performed in a single step, which is as easy as the assembly of contact cards.

Advantages of using tesa® ACF 8414:

  • Long-term reliable chip bonding and electrical connection in one step
  • Suitable for PVC, ABS, PET, and PC substrates
  • Good workability on all common assembly lines (no investment in machines dedicated to DI cards)
