Abstract:
Solutions for providing stackable electronics packaging are provided. In some embodiments, electronic components are accommodated in the cavity of a printed circuit board (PCB) or printed circuit assembly (PCA), or co-accommodated in adjoining cavities of adjacent, stacked PCAs or PCBs. The cavities allow for closer stacking of the PCAs or PCBs. In some embodiments, a PCA comprises an encapsulant conformally layered over a PCB with electronic components mounted on top and bottom. Power and/or signal channels are routed through the encapsulant to the top and/or bottom layers. The encapsulated PCAs may be stacked. In various embodiments, stackable PCAs are modular, facilitating customization.
Abstract:
A flexible flat cable connecting structure and a flexible flat cable connecting method are provided so that a connector can be connected by pitch conversion without complicating the structure of the connector and metal molds for forming mold parts become unnecessary. A flexible flat cable connecting structure for connecting a flexible flat cable (13) in which a plurality of rectangular conductors (11) are provided in parallel and a plurality of connector terminals arranged at an array pitch different from that of the rectangular conductors comprises an intermediate cable arranging member (17) one end of which is coupled to the connector terminals and in which a plurality of branch conductors (19) are provided in parallel which are set to have mutually different longitudinal dimensions according to the array pitch. The intermediate cable arranging member (17) is laid on the flexible flat cable (13) so that the intermediate cable arranging member (17) and the flexible flat cable (13) are in the same plane and form an angle. The other ends (21) of the branch conductors (19) of the intermediate cable arranging member (17) are connected to the respective rectangular conductors (11).
Abstract:
An electronic-circuit assembly of the present invention comprises a plurality of film carriers which are stacked. Respective film carriers have a plurality of through-holes. One of through-holes is provided on corresponding position to another through-hole in the stacked direction of the substrate. Two of adjacent film carriers are connected by the corresponding through-holes. A connection member is provided in two of adjacent through-holes in the stacked direction of the substrates. A connection state between film carriers can be easily checked. Since it is visually checked that solder appears inside the topmost through-hole. Furthermore, wiring lengths for connection between substrates can be reduced. Since the plurality of substrates are three-dimensionally connected.
Abstract:
A method of connecting two strips (1, 3) each provided with a conductor pattern, an insulating coating (9, 11) and a set of free conductor portions (5a, 7a) of the conductor pattern, which free conductor portions are disposed outside the coating. The strips are positioned in such a manner relative to one another that the one set of free conductor portions faces the other set of free conductor portions and the coatings overlap one another at least partly. After this, the two strips are pressed against one another and the one set of free conductor portions is soldered to the other set of free conductor portions. However, before the strips are pressed against one another an adhesive is applied to at least one of the coatings at such a location that after positioning of the strips the adhesive is situated in an overlapping area between the coatings. The adhesive is used for adhering the coatings to one another while the strips are pressed against one another and the one set of free conductor portions is soldered to the other set of free conductor portions.
Abstract:
A microwave or radio frequency (RF) device (300) includes stacked printed circuit boards (102, 152) (PCBs) mounted on a flexible PCB (206) having at least one ground plane and a signal terminal. Each of the stacked PCBs includes through-holes (120) the sidewalls of which are coated with a conductive material. Microwave components (110, 112, 154, 156) are mounted on the flexible PCB within the through-holes, such that signal terminals of the components bond to respective signal terminals of the flexible PCB. A conductive cover (132, 228) is mounted on the PCBs such that the cover is in electrical contact with the ground plane of the flexible PCB through the conductive material, forming shielding cavities around the components. The flexible PCB is folded such that the cover (132) of one PCB faces the cover (228) of the second PCB. The flexible PCB includes striplines or microstrips that carry RF or microwave signals to the signal terminals.
Abstract:
Fuse assemblies are disclosed. In one implementation, a fuse assembly may be disposed that includes a first portion of the second portion. The first portion may be formed of a first metal. The second portion may be formed of a second metal different from the first metal. The second metal may be copper, and the copper may be tin plated or silver plated.
