Abstract
When forming smartcards or pre-forms thereof additional functionality may be implemented by, for instance, incorporating components, such as a display device, and the like, by preparing pre-packages separately from the rest of the pre-forms and subsequently inserting the pre-packages into the pre-forms, thereby achieving superior process robustness and production yield.
Claims20
A pre-package for a smartcard, comprising
- a flexible printed circuit board including at least one non-planar circuit portion;
- and
- a stack of material layers that accommodates said flexible printed circuit board to provide a top surface and a bottom surface of said stack of material layers that are planar.
A method of forming pre-packages for smartcards, the method comprising
- providing an array of flexible printed circuit boards mechanically interconnected by a carrier material, each of said flexible printed circuit boards including at least one non-planar circuit portion;
- attaching said array of flexible printed circuit boards to a first layer of a smartcard compatible material;
- laterally enclosing at least said non-planar circuit portion of each of said flexible printed circuit boards in said array by attaching, for each of said non-planar circuit portions, a respective frame layer to said first layer, each of said frame layers having an opening so as to accommodate at least said respective non-planar circuit portion and level, at least partially, a non-planarity of said respective non-planar circuit portion;
- attaching a second layer formed of said smartcard compatible material to said first layer so as to form a planar bottom surface;
- and
- attaching a third layer formed of said smartcard compatible material to said frame layers so as to form a planar top surface.
