Abstract:
A method and an apparatus for providing a planar and compliant interface between a semiconductor chip (120) and its supporting substrate to accommodate for the thermal coefficient of expansion mismatch therebetween. The compliant interface is comprised of a plurality of compliant pads (110) defining channels (117) between adjacent pads. The pads are typically compressed between a flexible film chip carrier (100) and the chip. A compliant filler (170) is further disposed within the channels to form a uniform encapsulation layer having a controlled thickness.

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:
A notch portion (12) is formed by partly scraping the substrate material along a crease that has been set in advance in the insulating substrate (11), a first portion (14) and a second portion (15) that are divided along the crease are folded and are integrally joined together by using an adhesive or by welding. A conducting pattern (17) is formed on the surface of the insulating substrate (11) at the notch portion between the first portion and the second portion spanning across the crease, and wiring patterns are formed on both surfaces of the printed wiring board (20) being directly conducting to each other without the need to forming a through hole. Use of this printed wiring board makes it possible to realize various electronic devices such as liquid crystal display device, electronic printer, etc., as well as portable information devices in small sizes, reduced weight, decreased thicknesses and at reduced costs.

Abstract:
A laminated bus bar has thereon a male terminal formed either from only two electric strip conductors separated by a layer of insulation, or from two groups of conductors separated by a layer of insulation. When only two conductors are employed, one may be slightly longer and wider than the other, and the terminal section of the one conductor has a marginal edge portion thereof extending beyond the edge of the registering terminal section of the other conductor. Both terminal sections of the two conductors have exposed outer surfaces forming a male terminal disposed to be inserted releasably into a female receptacle of an electric circuit, and a dielectric insulator barrier is secured on and covers the marginal edge portion of the terminal section of the one conductor and overlies the edge of the other terminal section. When each terminal section constitutes a group of spaced, parallel conductors one of two, like insulator barriers is secured to each side of the insulation separating the two groups, and has in one edge thereof spaced notches for accommodating and covering the edges of all conductors in the registering group thereof.
