Circuit type metal foil sheet for resonant frequency characteristic tag and manufacturing method thereof

摘要

The present invention relates to a circuit-type metal foil sheet for a resonant tag or a method of manufacturing the same. The circuit-type metal foil sheet provides a lamination by attaching a metal foil whose surface is covered with a hot melt adhesive resin film to a carrier sheet such as paper or plastic film by using an adhesive whose adhesive force increases by heating, and the metal foil side of the lamination is plastic Superimposing on a support such as a film and transferring the circuit-like metal foil to the surface of the support by heating the circuit pattern from the support side or the carrier sheet side. The circuit board including the resonant circuit or the wiring circuit is very precise without using an etching process in which no chemical is used.
