Typical existing antenna clips use multi-piece configurations that are manufactured through the assembly of the antenna contact terminal to an injection moulded base, with separate fixing pins to support the SMD interface. This approach increases complexity and quality risk, as well as increasing manufacturing costs.
Autosplice crush-proof antenna clips integrate both the antenna contact and the base into a unified single-piece stamping that improves reliability and reduces cost. Since the entire contact is formed from stamped copper alloy, contact resistance and mechanical stability during vibration are superior to multi-piece designs. In addition, the footprint of the one-piece contacts can be significantly smaller, requiring less PCB space and allowing for overall better fit, form and function. The clips are also available in a variety of heights to accommodate specific antenna and product design requirements while minimising PCB real estate usage.
One of the major challenges for integrating NFC into a product is making sure that the antenna will meet the requirements of NFC standards, such as ISO 14443B and NFC-Forum Type 4 tag compliance. Successful integration depends on precision control of the size, shape, material and positioning of the antenna, along with the need for robust resistance to vibration and shock under a wide range of operating conditions. The Autosplice design can provide maximum configuration flexibility and reliability while also minimising cost and size.
