Abstract:
1. A chip card for insertion into an electronic device that is provided with a holder, which holder is equipped with electrical device contacts and a press-on device, the chip card comprising: an electrically insulating planar substrate with a first major surface, an opposing second major surface, and a perimeter edge surface; a metallic planar contact field applied to the first major surface of the electrically insulating planar substrate; a chip located on the second major surface of the electrically insulating planar substrate and electrically connected to the metallic planar contact field; and a single-piece injection molded encapsulation located on the second major surface of the electrically insulating planar substrate and enclosing the chip, wherein the single-piece injection molded encapsulation is a monolithic structure that is located directly on the chip and on the second major surface of the of the electrically insulating planar substrate to form a solid structure that is free of a cavity; wherein the single-piece injection molded encapsulation, with no further encapsulation material required, has such a thickness that, on insertion of the chip card into the holder, the single-piece injection molded encapsulation has body contact with the press-on device of the holder, the contact field has body contact with the device contacts of the holder, and the contact field is reliably electrically contacted to the device contacts of the holder; wherein a top base surface of the single-piece injection molded encapsulation is at least as large as the contact field without projecting beyond the perimeter edge of the substrate; and wherein the perimeter edge of the substrate projects beyond a perimeter edge of the single-piece injection molded encapsulation and beyond a perimeter edge of the contact field.
