Implantable transponder and improved method of assembly

摘要

An improved identification marker and method of assembling the marker is provided, which includes the steps of providing a glass vial and filling the glass vial with a quick curing liquid to a predetermined volume corresponding to at least the volume wherein the unfilled volume of the vial is equal to the displacement volume of an IC circuit hybrid and antenna. The IC circuit hybrid and antenna are placed in the vial so as to be entirely enveloped by the liquid. A cap is placed on the vial and the liquid is cured. Preferably, the cap is an anti-migration cap so that when the transponder is implanted in an animal, it prevents the transponder from sliding out.
