A flexible electrical contact is formed as a convex dome structure extending from one side of a surrounding structure, with the convex dome structure and the surrounding structure forming an integral metallic structure. The convex dome structure includes a central contact portion and a number of legs extending between the central contact portion and the surrounding structure. Each leg extends radially outward from the central contact portion and circumferentially around part of the central contact portion. A number of convex dome structures of this kind may be part of a removable shield in an electronic enclosure, provided to electrically ground the shield to a conductive frame, reducing the level of RFI (radio frequency interference) emissions from a device. Alternately, a number of convex dome structures may be provided along spring strips fastened to such a shield. In such spring strips, electrical contact may occur between the shield and intermediate positions along the length of the legs.

Method and apparatus for manufacturing formed, plated component parts in a continuous production run which includes component parts of alternate configurations by advancing a strip of material of indeterminate length, within which strip the component parts are carried, through a plating operation continuously while the forming operation is modified to accommodate the alternate configurations without interrupting the continuity of the plating operation so as to enable relatively long uninterrupted production runs which include, within the longer runs, shorter runs of each of the alternate configurations. In addition, the formed and plated component parts are severed from the strip by a severing operation which is modified to accommodate the alternate configurations to deliver individual formed, plated component parts.

A shielding enclosure has an access opening for enabling selective access to a component placed in the shielding enclosure, a closure member and a connector section selectively expansible and contractible to enable the closure member to be captured within the access opening upon expansion of the connecting section to complete shielding of the component and to be disengaged from the access opening upon contraction of the connecting section. In the preferred construction, the connecting section is in the form of a perforated web having beams oriented oblique to the directions of expansion and contraction, and the shielding enclosure is made in one piece from a single blank of shielding material.

In the manufacture of RFID tags, electronic components are connected with soldered connections to antennas stamped from a thin strip of electrically conductive metal, utilizing methods and intermediate products which enable accurate registration of the leads of the electronic components with contacts on the antennas. Thus, a strip of metal is provided with contact members unitary with the strip and coupled to the strip through compliant coupling arrangements which allow compliant movement of the contact members relative to the strip for accurate alignment with electronic components juxtaposed with the contact members for soldered connections between the leads of the electronic components and the corresponding contact members. The antennas, with the electronic components soldered in place, are carried by a substrate, and the sequence of the stamping and soldering operations avoids exposing the substrate to the heat of soldering.

A shielding gasket is affixed to a shield housing for interposition between the shield housing and a circuit board of an electronic device. The circuit board includes a plurality of electronic components and related circuitry and the arrangement of the shield housing and the shielding gasket provide for inter-component shielding of the plural electronic components from one another, together with corresponding related circuitry, as well as overall shielding of the plural electronic components on the circuit board. To that end, the shielding gasket includes partitions integral with the shielding gasket for extending between the electronic components, the partitions engaging the shield housing such that the shield housing and the partitions complete inter-component shielding of the electronic components and related circuitry from one another.

A smart card reader includes a housing having a rectangular plan configuration and housing members secured together by sets of complementary overlapping tabs located at the four corners of the rectangular housing and joined together, as by welding. Some of the sets include locator elements on one of the tabs of the set for locating the overlapped tabs accurately relative to one another to assure accurate dimensions in the completed housing. A stiffener plate is secured to at least one of the housing members, as by welding at spaced apart locations along the stiffener plate, to add stiffness to the housing. A lead-in ramp assists in leading the smart card from an inlet section of the reader into an intermediate section of the reader for connection to an electrical connector located in a connector section of the reader.
