A method of constructing an RFID unit can include using a protective layer to hold an integrated circuit chip module to a substrate layer with an antenna unit while a conductive adhesive has not yet fully set.
Abstract:
A component alignment casing system for connecting circuits, and a method for making or assembling the component alignment casing system is disclosed. The system has at least one surface mountable component which has a plurality of exposed leads, a prepared component which has a plurality of exposed traces, an alignment base onto which the prepared component and the surface mountable component are laid, and a compressive cover that attaches to said alignment base. The alignment base has a plurality of alignment ribs to isolate and align the exposed traces of the prepared component. The prepared component and surface mountable components are electrically connected and attached together, preferably by soldering. The method comprises laying the prepared component on the alignment base and ribs, and overlaying the surface mountable component, with its exposed leads, on to the alignment base and the prepared component, and electrically connecting the components together, preferably by soldering, to the alignment base. The cover is then snapped on, and supplies compressive force to assure good contact between the leads of the surface mountable component and the traces of the prepared component.
Abstract:
A self centering coil (200) includes a coil section (202) and also having curved end section (206) and (204) at opposite sides of the coil section (202). The curved end sections are preferably substantially flat and in a plane which is parallel to the center axis (306) of the coiled section (202).
Abstract:
A component for surface mounting is fixed by means of adhesive to a surface of a member. For improving the adhesion, the fixable surface of the component includes a structure which makes it possible, first, for this fixable surface to lie flush against the surface of the member. Second, the structure of the fixable surface also makes it possible for a quantity of adhesive adequate for fixing to remain between the fixable surface of the component and the surface of the member.
Abstract:
An inductance element comprises conductive paths of copper and a spool member arranged on a substrate, and insulated winding formed by a fine copper wire whose surface is coated with an insulating film of urethane etc. is wound around the spool member so that both end portions thereof are subjected to ultrasonic vibration by an ultrasonic bonding apparatus to be connected to the conductive paths by ultrasonic bonding. Thus, the end portions of the winding can be processed by local heating with application of ultrasonic vibration, whereby the coil needs not be entirely heated and an inductance element can be readily implemented directly on the substrate.
Abstract:
An electronic device is provided. The electronic device includes a display including a display area and a connecting area extending from one side of the display area, a flexible printed circuit board (FPCB) connected with the connecting area, and a first module mounted on a first surface of the FPCB, where the connecting area is bent such that the first module is apart from the display to face the display.
Abstract:
Power amplifier assemblies and components are disclosed. According to some embodiments, a power amplifier assembly (10) is provided that includes a power amplifier (12) having a gate lead (14) with a gate contact surface, a drain lead (13) with a drain contact surface and a source contact surface (15) having a length and width. An extended heat slug (11) is mounted against the source contact surface to conduct heat away (18) from the surface and to extend the electrical path of the source. The extended heat slug has at least a length that is greater than the length of the source contact surface.
Abstract:
A capacitor holder includes: a cylindrical portion made of a resin having a cylindrical shape and externally fitted to a capacitor; a pair of protrusions formed integrally with the cylindrical portion, the protrusions protruding in an outward direction of the cylindrical portion from positions opposed to each other with respect to an axis of the cylindrical portion; and a pair of metal pins protruding along the axis from axial end surfaces of the paired protrusions, the metal pins configured to solder the cylindrical portion and the protrusions to a printed circuit board. In the capacitor holder, a distance between the axis and outer circumferences of the protrusions is less than 0.76 times of an inner diameter of the cylindrical portion.
Abstract:
The invention relates to a method of joining at least two components (12, 16, 36) of an electrical circuit module (30) for establishing a mechanical and electrical interconnection between the components (12, 16, 36), wherein the joining is realized by a sintering process for sintering a metal joint (26, 34) between the components (12, 16, 36) and wherein ultrasonic vibration energy is supplied at least temporarily during the sintering process for supporting said sintering process. The invention further relates to a corresponding composite (10) comprising at least two components (12, 16, 36) of an electrical circuit module (30) and a corresponding electrical circuit module (30).
