Abstract:
An electromagnetic interference shield includes a polymer thin film metalized with conductive metals and a solderable material deposited over the conductive metals. The solderable material has a low melting temperature so that the solder can be heated to form a weld joint between a chip (or component) and the solder without damaging the metalized polymer thin film. One example of a low melting temperature solder is SnBi.

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 (107) is coated with a layer of solderable material (110) 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 (120) between a chip (115) and the solderable material without damaging the chip.
