Claim 18:
19. A method for assembling a biometric sensor module, comprising:
providing a biometric sensor comprising an array of sensing elements for acquiring sensing signals indicative of a biometric feature of a user, the array of sensing elements arranged facing towards a front side of the biometric sensor;
attaching a bottom flexible film to a back side, opposite the front side, of the biometric sensor, the bottom flexible film carrying at least one electrically conductive line, wherein the biometric sensor is attached to a first side of the bottom flexible film, the bottom flexible film further carrying at least one electrically conductive pad on a second side opposite the first side, the at least one electrically conductive pad being electrically connected with the at least one electrically conductive line;
forming an electrical connection between at least one electrically conductive line and the biometric sensor,
attaching the biometric sensor to a top film closer to the front side of the biometric sensor than the bottom flexible film;
bending the bottom flexible film towards the top film along sides of the biometric sensor, such that the bottom flexible film is attachable to the top film adjacent to bent portions of the bottom flexible film.
