Abstract:
A technique for making acicular, branched, conductive dendrites, and a technique for using the dendrites to form a conductive compressible pad-on-pad connector are provided. To form the dendrites, a substrate is provided on which dendrites are grown, preferably on a metal film. The dendrites are then removed from the substrate, preferably by etching metal from the substrate. The so formed dendrites are incorporated into a compressible dielectric material, which then forms a compressible pad-on-pad connector between two conducting elements, such as connector pads on electrical devices, e.g. an I/C chip mounted on a substrate, such as a chip carrier.
Abstract:
A printed circuit board arrangement for printed circuits with electronic components has a first board having a first electric partial circuit and having a first edge formed as a first contact comb with successively arranged first projections and first cutouts. A second board having a second electric partial circuit and having a second edge formed as a second contact comb with successively arranged second projections and second cutouts is provided, wherein the second contact comb is configured to be complementary to the first contact comb. The first and second boards are combined to form a complete circuit with the first and second boards substantially positioned in a common plane. The first projections engage captively the second cutouts, and the second projections engage captively the first cutouts.

Abstract:
A stiffener in the form of a metal-cored stiffener plate is temporarily secured to the underside of a printed circuit (PC) board having a series of integrated circuit (IC) chips and other electronic components and metallization interconnect traces on the upper or top surface of the board. Securing of the stiffening plate and PC board is provided by segments of a hook/mushrooms-containing flexible tape adhered to the PC board underside by suitable adhesive. A complementary sheet of a hooks-containing flexible material is adhered to the stiffening plate such that upon pressing of the complementary material and segments together the respective hooks and loops interlock binding the PC board assembly and stiffening plate assembly together. The securement can be easily undone by grasping and levering the edge of the stiffening plate from the PC board and breaking the interlock of the hooks and loops. The hooks and loops may be reversed on the stiffener plate and on the solder-side of the PC board. They may be the well-known complementary Velcro.RTM. materials.
Abstract:
The present invention comprises apparatus for connecting and disconnecting substantially planar arrays of optoelectrical contact sites in a mechanically secure and functionally rapid and reversible manner. The invention utilizes technology available in the zipper manufacturing industry, to achieve a high contact site density by suitably disposed contact sites for opotoelectronic connections on zipper teeth, and through the use of a conventional zipper-type runner achieving the interconnection of a multiplicity of optoelectrical contact sites.

Abstract:
Disclosed are a method and system to reduce impedance of printed circuit boards through an interconnecting of printed circuit boards using a square wave pattern of plated-through holes. A method of connecting a first printed circuit board to a second printed circuit board comprises forming a square wave pattern of the first printed circuit board and the second printed circuit board and adjoining the first printed circuit board and the second printed circuit board. The method also involves producing plated-through holes along the square wave pattern, a top section, and/or a bottom section of the adjoined first printed circuit board and second printed circuit board. The method further involves securing the top section and the bottom section using a first metal clip and a second metal clip, respectively, and connecting the first printed circuit board to the second printed circuit board by a wave soldering process.
Abstract:
An RFPCB includes a reinforcement layer and at least two FPCBs spliced together to match the reinforcement layer in shape and size. The FPCBs are adhered onto the reinforcement layer. The reinforcement layer includes circuits connected with the FPCB and has portions removed to obtain a desired flexibility.
