Patent ID: 8540165

Claim:
An electronic card assembly, comprising: a top and a bottom graphic layer, a top and a bottom thermal sensitive adhesion tape and an inlay assembly laminated together, said inlay assembly having an inlay assembly top surface and an inlay assembly bottom surface, the top thermal sensitive adhesion tape being located between the top graphic layer and the inlay assembly top surface, the bottom thermal sensitive adhesion tape being located between the bottom graphic layer and the inlay assembly bottom surface; wherein the inlay assembly is comprised of: an inlay sub-assembly comprising a printed circuit board (“PCB”) assembly having a PCB base and one or more electronic components mounted to the PCB base, an inlay sub-assembly thermal sensitive adhesion tape and a stiffening substrate laminated together, said inlay sub-assembly thermal sensitive adhesion tape being located between the PCB base and the stiffening substrate; a battery mounted to the inlay sub-assembly in a battery opening of the stiffening substrate on top of the inlay sub-assembly thermal sensitive adhesion tape and in electrical connection with the PCB base; and a battery insert mounted in the battery cavity on top of the inlay sub-assembly thermal sensitive adhesion tape between the battery and the stiffening substrate; wherein the stiffening substrate has a thermal coefficient that is substantially the same as that of the PCB base; and wherein the battery insert has a greater bending flexibility than the stiffening substrate.
