A printed circuit board is provided with a flexibly attached limb or tab on which an encapsulated electronic component or assembly is mounted, such that the encapsulated portion can assume its own orientation in a completed device incorporating the board. As shown (Fig. 4), a smart card comprises a printed circuit board 17 sandwiched between two plastic laminae 23, 24. An encapsulated electronic sub-assembly 19 is mounted on a portion 22 of the board 17 which is only attached to the main portion of the board 17 by a flexible bridge portion (not shown) which bears the connections. Accordingly the potted components are able to adopt a centralised position between the surface laminae 23, 24. <IMAGE> |
