    摘要: A selectively releasing runner and substrate assembly (10) comprises a plurality of conductive runners (16) adhered to a substrate (12). A portion (18) of at least some of the conductive runners have a lower adhesion to the substrate for selectively releasing the conductive runner from the substrate when subjected to thermal stress. The selectively releasing runner and substrate assembly is made by selectively depositing an adhesion layer (14) of a first metal to portions of the surface of the substrate where maximum adhesion is desired. The other portions of the substrate are not covered with the first metal. The first metal layer and the uncovered portions of the substrate surface are covered with a second metal layer (16). The adhesion of the second metal layer to the substrate is less than the adhesion of the second metal layer to the first metal layer, and less than the adhesion of the first metal layer tot he substrate. The second metal layer may be copper. Additionally, an electronic component (22), such as an integrated circuit, may be attached to the selectively releasing metal portion.

    摘要: A molded thermoplastic housing (100) includes base (102) and cover (104) members joined by a living hinge (106). The base member (102) includes a peripheral wall (108). Four solderable printed circuit patterns (112, 114, 116 and 118) are vacuum deposited onto the interior and exterior surfaces of both housing members. The printed circuit patterns on opposing surfaces of the base and cover members are joined by conductive through-holes (e.g., 120 and 122), while the printed circuit patterns on the interior surfaces of the base and cover members are joined by an interconnecting printed circuit pattern (124) which is vacuum deposited onto the living hinge. Mylar sheets (132) are adhered to the exterior surface of the housing to insulate the exterior printed circuit patterns. An antenna pattern (126) is also vacuum deposited onto an exterior surface of the housing. A switch (136) and battery contact (152) are integrally formed with the housing and an integrally molded structural support means strenghthens the housing members. The housing is manufactured "opened up" and, at the final assembly stage, the cover member is rotated about the hinge until it contacts the upper surface of the peripheral wall (108B). Snap-fit connectors (e.g., 110) join the cover to the base.

    摘要: Printed circuit patterns are photolithographically defined on a three dimensional "projection" surface (204) of a printed circuit substrate (202) using a projection image aligner and a photomask (210) having a planar image (210A). The geometry of the projection is restricted such that the slope of the projection surface, as measured at any point on the projection surface and relative to a reference plane which is parallel to the focal plane of the projection image aligner, is less than 90 degrees. A solution of photoresist includes a photoresist solvent, a fluorosurfactant and an aromatic hydrocarbon solvent, and is preferably sprayed over the projection surface. In one method of manufacture, the printed circuit substrate is moved from one position to another during the exposure of the photoresist layer (206). In another method, after a first portion of the projection surface is exposed by a first photomask (502), a second photomask (504) is substituted and the remainder of the projection surface exposed. In still another method, a photomask having a plurality of planar images (604A, 604B and 606A) each image being positioned parallel to the others but separated by a small distance, is used to simultaneously exposed the entire projection surface.

    摘要: The preferred housing includes an integrally molded thermoplastic base (102) and cover (104) assembly. The cover is joined to the base by a living hinge (106) and a peripheral wall (108) extends around the perimeter of the base. In one embodiment, the antenna is a wire loop (204), the wire being wound in an external circumferential groove (202A) in the peripheral wall or, alternatively, integrally molded into the peripheral wall. Other embodiments use printed circuit loop antenna patterns that are preferably vacuum deposited directly onto the thermoplastic base and/or cover. When the antenna pattern is disposed on both the cover and the base, a portion of the antenna (e.g., 1002K) is also disposed on the hinge to join the main portions of the antenna on the base and cover. In one embodiment of the printed circuit loop antenna, the plane of the loop lies parallel to the base and may include one or more turns or loops (e.g., 402C, E, G and J). In another embodiment, the loop includes a 90 degree bend (e.g., 504) and both planes of the loop lie perpendicular to the base. In still another embodiment, the loop includes three 90 degree bends, a crossover at one of the bends (e.g., at 704), and all four planes of the loop lie perpendicular to the base.
