Abstract:
A process is disclosed for manufacturing printed circuit boards, printed circuit foils and semifinished products for printed circuit boards and printed circuit foils from blanks with electroconductive layers (7, 8) that may be structured into conductive patterns and substrates (4) that may be structured for forming connecting means (V), profiles (K) and conductive patterns (L). The connecting means (V), profiles (K) and conductive patterns (L) are structured at the same time or in the same process steps on the blanks. The connecting means (V) and the profiles (K) are part of the structured substrate (4) of the blanks. The electric or mechanical connecting means (V) are placed in a position in which they may be connected and the finished conductive patterns (L) may be detached around the profiles (K).
Abstract:
Die Erfindung bezieht sich auf ein elektronisches Schaltungsmodul mit einer Leiterplatte (1) mit einer elektrisch isolierende Schicht (2), die eine erste Metallschicht zur Bildung von Leiterbahnen und zum Tragen von oberflächenmontierbaren Bauelementen aufweist. Um den Platzbedarf des elektronischen Schaltungsmoduls zu verringern wird vorgeschlagen, daß die Leiterplatte (1) mindestens eine Biegekante aufweist, an der die elektrisch isolierende Schicht eine Vertiefung aufweist und um die ein Abschnitt der Leiterplatte umgebogen ist.

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.
Abstract:
A method of forming conductive end portions on a flexible circuit member (15) having a dielectric layer (19) (e.g., polyimide) with at least one conductive element (41, 43, 45) (e.g., copper) thereon. The method comprises the steps of forming (e.g., punching) an opening through both dielectric and conductive element, providing (e.g., additive plating) an electrically conducting layer on the opening's internal surface, providing (e.g., electroplating) a plurality of dendritic elements on the conducting layer's surface, and thereafter removing (e.g., punching) a portion of the dielectric and conductive element such that the formed dendritic elements (e.g., palladium) project from the flexible circuit's conductive ends.
