Abstract
The present invention refers to a pre-package for a flexible printed circuit board for a smartcard. The pre-package comprises a flexible printed circuit board including one or more non-planar circuit portions; a first layer of a first material at least partially covering a first side of the flexible printed circuit board so as to form a planar layer; a second layer of a second material covering a second side of the flexible printed circuit board; and a third layer comprising a hardening material at least partially covering the first side so as to form a planar layer. The third layer has a third hardness value which is higher than the first hardness value and/or than the second hardness value of the first and second dielectric materials, respectively. The pre-package may be advantageously inserted into a smartcard having a suitable window for accommodating the pre-package comprising the electronic components. The present invention also refers to the methods for forming the pre-package and the smartcard comprising it.
