Abstract:
Mehrere Leiterplattenstücke einer räumlichen Leiterplattenanordnung einer elektronischen Baugruppe werden bekanntermaßen über Folienverbinder elektrisch miteinander verbunden und in der Raumform um ein Bedien- oder Aktorelement angeordnet. Die Montage derartiger Baugruppen ist jedoch sehr aufwendig, da die Leiterplatten alle mechanisch befestigt werden müssen. Durch Verwendung von Folienverbindern mit einer höheren Steifigkeit können Leiterplattenstücke direkt über diese ohne zusätzliche mechanische Arretierung gehalten werden und die räumliche Leiterplattenanordnung bereits durch eine Arretierung in der Raumform gesichert werden. Verwendung für elektronische Baugruppen mit Bedien- und/oder Aktorelementen bei hohen Anforderungen an den Platzbedarf, insbesondere für KFz-Baugruppen
Abstract:
A molded electrical interconnection system (1) includes a three-dimensional molded dielectric substrate (3) including at least one open socket (4). Stamped and formed electrical circuitry (2) is embedded in the molded substrate (3) and includes a contact blade (2b,2c) projecting into the socket (4). An interface module (5) is positioned in the socket (4) to define a receptacle for receiving a male terminal (19) of a complementary connecting device.
Abstract:
The probe card assembly (500) includes a probe card (502), and a space transformer (506) having resilient contact structures (524) mounted to and extending from terminals (522) on its surface. An interposer (504) is disposed between the space transformer and the probe card. The space transformer and interposer are stacked on the probe card and the resilient contact structures can be arranged to optimise probing of entire wafer.

Abstract:
A cutout portion (12) is formed by cutting out partly a board material along a fold predetermined in an insulating material (11), and a first portion (14) and a second portion (15) partitioned along the fold are folded and attached together into a unitary body by means of a bonding agent or thermal fusing. Formed on the surface of the insulating board (11) is a conductor pattern (17) that continuously runs across the fold at the cutout portion between the first portion and the second portion, and thus the conductor pattern assuring continuity between both sides of a printed wiring board (20) results without the need for providing through-holes. By employing such a printed wiring board, a compact and low-cost feature is implemented into electronic apparatuses or portable information apparatuses such as liquid crystal display devices or electronic printers, through a miniature, light-weight and flat design effort.
Abstract:
A connector for microelectronic elements includes a sheet-like body (30) having a plurality of holes (36), desirably arranged in a regular grid pattern. Each hole is provided with a resilient laminar contact (38) having a plurality of projections (42) extending inwardly over the hole in the body. Microelectronic elements (68) having bump leads (70) such as solder balls thereon may be engaged with the connector by advancing the bump leads into the holes of the connector to engage the bump leads with the contacts. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.
Abstract:
An interconnection contact structure assembly including an electronic component (102) having a surface and a conductive contact terminal (103) carried by the electronic component (102) and accessible at the surface. The contact structure (101) includes an internal flexible elongate member (106) having first (107) and second ends (108) and with the first end (107) forming a first intimate bond to the surface of the conductive contact terminal (103) without the use of a separate bonding material. An electrically conductive shell (116) is provided and is formed of at least one layer of a conductive material enveloping the elongate member (106) and forming a second intimate bond with at least a portion of the conductive contact terminal immediately adjacent the first intimate bond.
Abstract:
This invention relates to three dimensional packaging of integrated circuit chips (306) into stacks to form cube structures. Between adjacent chips in the stack, there is disposed an electrical interconnection means which is a first substrate (300) having a plurality of conductors (316) one end of which is electrically connected to chip contact locations and the other end of which extends to one side of the chip stack to form a plurality of pin-like electrical interconnection assemblies. The pin-like structures (318) can be formed from projections of the first substrate having an electrical conductor on at least one side thereof extending from this side. Alternatively, the pin-like structures can be formed from conductors which cantilever from both sides of an edge of the first substrate corresponding conductors from both sides are aligned and spaced apart by the first substrate thickness. The spaces contains solder and form solder loaded pin-like structures. The pin-like structures can be directly solder bonded to conductors on a second substrate (302) surface or the pin-like structures can be adapted for insertion into apertures (320) in a second substrate. The second substrate provides a means for electrically interconnecting a plurality of these cubes. Preferably, the first and second substrates are circuitized flexible polymeric films. The second substrate is disposed on a third substrate, such as a PC board, with a resilient material therebetween which permits a heat sink to be pressed into intimate contact with an opposite side of the cube.
