    摘要: A method for securing a metallic substrate (24) to a metallic housing (26). The method may include: firing a first solderable coating (64) to an edge (60) of the metallic substrate (24); firing a second solderable coating (64) to a groove (62) of the metallic housing (26); joining the edge (60) of the metallic substrate (24) to the groove (62) of the metallic housing (26) to form a joint (66) at the first solderable coating and the second solderable coating; applying a solder (68) to the joint (66); and solder bonding the metallic substrate (24) to the metallic housing (26) to provide a hermetic seal at the joint (66). There is also an electronic control module that incorporates the method.

    摘要: A flexible circuit (100) includes a first circuit path portion (110) and a second rigid circuit path portion (140) to which electronic components (102) may be coupled. Each circuit path portion (110 and 140) including a resin layer (112 and 142) and an adjacent conductive layer (114 and 144). Each circuit path portion (110 and 140) defining a gap (120 and 150) substantially running along a line corresponding to a desired bend location. A central circuit path portion (130) is disposed between the first circuit path portion (110) and the second rigid circuit path portion (140) and includes a first conductive layer (134) in electrical communication with the first circuit path portion (110) and a second conductive layer (136) in electrical communication with the second rigid circuit path portion (140), so as to provide electrical communication across the gaps (120 and 150). A metal plate (160) is disposed adjacent the second rigid circuit path portion (140).

    摘要: A method of making a multilayered circuit board wherein at least two layered subassemblies, each comprising a dielectric layer and at least one conductive layer therein, are bonded together. Each subassembly includes a through-hole extending therethrough which is aligned with a respective through-hole of the other prior to bonding. The subassemblies are compressed at a predetermined pressure (e.g., 300 psi) and then heated to a first temperature (e.g., 300.degree. C.) for an established time period, resulting in formation of a bond between the two through-holes. The resulting alloy formed from this bond possesses a melting point significantly greater than that of the subassembly dielectric (e.g., PTFE). Following this time period, the compressed subassemblies are heated to an even greater temperature (e.g., 380.degree. C.), again for an established time period, to assure dielectric flow. The subassembly is then cooled and the pressure removed. The method possesses two significant features: (1) effective engagement between respective pairs of through-holes in the compressed subassemblies; and (2) prevention of dielectric incursion within the bond formed between the respective pairs of through-holes, which incursion could adversely affect the electrical connection therebetween.
