Abstract
An RFID antenna that is protected from corrosion and is configured for easy attachment to an electronic chip is very advantageous. The electrically conductive RFID antenna pattern is coated with a layer of solderable material that protects the copper from corroding. The solderable material has a low melting temperature so that the solderable material can be heated to form a weld joint between a chip and the solderable material without damaging the chip.
