Abstract:
A printed circuit board which is of such a construction that patterns of electrically conductive strips and/or pads of either standard or non-standard form can be readily provided comprises a rigid board 1 of which at least the major surfaces are of electrically insulating material, which has extending through the board a multiplicity of holes 2 arranged in a pattern of rows and columns and which carries on one or each of its major surfaces a multiplicity of annular metal islands 3 each bounding a hole in the board and discrete with respect to the other annular islands. The rigid board 1 may also carry on said one or each of its major surfaces supplementary metal islands 4 and 5 each positioned between and discrete with respect to annular islands bounding adjacent holes in the rigid board. A circuit of either a standard or non-standard pattern can be formed by electrically interconnecting selected adjacent metal islands 3, 4 and 5 with local deposits of material of high electrical conductivity in such a way as to bridge the gap between adjacent islands. The local deposits may be effected manually but are preferably effected automatically using a modified computer aided design plotter or an automatic fluid dispensing machine.
Abstract:
Procédé et appareil (10) permettant de former des systèmes de distribution d'alimentation électrique ou des parties de ceux-ci pendant des opérations de poinçonnage. Un organe plan (16) en matériau conducteur est placé à proximité d'un substrat (14) sur lequel le système de distribution d'alimentation électrique ou une partie de celui-ci doit être formé. Un poinçon (18) est utilisé pour former les conducteurs (12) à partir de l'organe plan (16) et pour déposer les conducteurs (12) sur le substrat (14). L'action du poinçon (18) provoque une interférence mécanique entre le conducteur (12) et le substrat (14) fixant ainsi le conducteur sur le substrat. Le système de distribution d'énergie électrique ou une partie de celui-ci peut comprendre un ensemble de bornes électriques, un commutateur électrique, un puits thermique d'un module électronique ou un plaque à circuit électrique.
Abstract:
s7 The invention relates to a method of interconnecting conductors of different layers (2, 4) of a multilayer printed circuit board by forming a depression in the relevant conductor of the outermost layer (4) so that the insulation layer(s) (3) is deformed and contact is made between the outermost layer (4) and the appropriate conductor(s) of the next layer or layers (2). The method can suitably be used in multilayer printed circuits on a substrate and in flexible multilayer printed circuits on an electrically insulating foil. In the latter case a temporary backing surface is required for the depression process. The substrate (1) or the temporary backing surface must be deformable to a sufficient degree.
Abstract:
Un circuit électrique (32) se compose d'une pluralité de couches (30, 100), chaque couche (30, 100) comprenant un ou plusieurs cheminements électriques (36, 38), chaque couche (30, 100) comprenant également une isolation (34) isolant au moins une partie d'une couche (38) d'une autre couche (100). Les cheminements (36, 38) comprennent des motifs répétitifs (40, 42). Chaque cheminement (36, 38) de chaque couche (30, 100) peut communiquer avec les cheminements (36, 38) des couches adjacentes (30, 100). Quelques parties des motifs (40, 42) qui comprennent les cheminements (36, 38) de chaque couche (30, 100) peuvent être au moins partiellement alignées avec quelques parties des motifs (40, 42) des cheminements (36, 38) des autres couches (30, 100). D'autres parties des cheminements (36, 38) des couches (30, 100) restent non alignées. Un laser à impulsions (134) peut être utilisé pour sectionner les parties non alignées des cheminements (36, 38), de manière à créer le circuit électrique désiré (32). Des composants peuvent être fixés sur le circuit électrique selon les besoins. En outre, un tel circuit peut être utilisé dans la construction des couches de métallisation finales de puces telles que des réseaux de portes.
