Abstract

The invention consists in making an adhesive which conducts electrical and electronic currents, characterised by an agglomeration of particles of conductive metals of the type: copper, bronze, iron, etc., joined by inorganic or organic binders, which allow passage of the electric current, by offering a very low resistance once dry. This adhesive can be used in silk screen printing, for stencilling or in the form of a pressurised dispensing flask, and for making three-dimensional elements.

Description

La présente invention concerne la fabrication d'une colle conductrice de l'électricité. The present invention relates to the manufacture of an electrically conductive adhesive.

Cette colle est composée d'une part d'un produit colloidal et d'autre part de particules conductrices de courant électrique. This adhesive is composed on the one hand of a colloidal product and on the other hand of electrically conductive particles.

Actuellement il est normal d'utiliser la soudure à l'étain pour réunir des éléments généralement en cuivre. Currently it is normal to use tin solder to gather elements generally copper.

Dans de nombreux cas il est préférable d'utiliser une colle qui permet d'éviter la présence de la soudure et évidemment du fer à souder surtout dans les composants très sensibles à la chaleur. De même cette colle permet à des élèves ainsi qu'aux débutants de s'initier aux systèmes électroniques. De même cette composition permet de fabriquer des encres utilisables en sérigraphie ou au pochoir. Par rapport au système de fabrication des circuits imprimés, celui-ci évite l'utilisation d'agents agressifs tels que : perchlorure de fer acides etc...In many cases it is preferable to use an adhesive which makes it possible to avoid the presence of the solder and of course the soldering iron, especially in components that are very sensitive to heat. In the same way, this glue allows students as well as beginners to learn about electronic systems. Similarly, this composition makes it possible to produce inks that can be used in screen printing or in stencil. Compared to the printed circuit manufacturing system, it avoids the use of aggressive agents such as: acid ferric chloride, etc.

Il est possible de conditionner cette colle dans un flacon verseur par pression de façon à étaler uniformé- ment les produits d'un point, à un autre sur une plaque destinée à recevoir ce circuit fait manuellement. Ce procédé évite l'utilisation de systèmes compliqués. Il est surtout utilisable lors de la création de circuits prototypes. It is possible to condition this glue in a pressure pourer so as to uniformly spread the products from one point to another on a plate intended to receive this circuit made manually. This method avoids the use of complicated systems. It is especially useful when creating prototype circuits.

La colle électronique se compose d'une part de parti cules métalliques : cuivre, bronze, fer, or, argent étain etc : tous composants conducteurs de l'électricité. D'autre part la colle est de nature diverse : elle peut être r < > mposée de résines acryliques, vinyliques, d'acétate de cellulose ou de polyuréthane etc. Epoxy ou même de colles minérales du type silicate. The electronic glue consists on the one hand of metallic particles: copper, bronze, iron, gold, tin silver, etc: all electrically conductive components. On the other hand the glue is of various nature: it can be rposed of acrylic resins, vinyl, cellulose acetate or polyurethane etc. Epoxy or even mineral glues of the silicate type.

Il est éssentiel que le mélange soit fait d'une façon telle que le métal soit prédominant afin que la conductibilité du mélange une fois sec puisse laisser passer les micro courants nécessaires. It is essential that the mixture be made in such a way that the metal is predominant so that the conductivity of the mixture once dry can pass the necessary micro currents.

Par exemple : Bronze : à l'état de limaille fine 1 part en volume, Colle en milieu solant : 2 part en vo-lume.  For example: Bronze: in the state of fine filings 1 part in volume, Glue in soling medium: 2 part in vo-lume.

Afin de pouvoir conserver la colle pendant un
certain temps avant son utilisation il est 30uhai- -table d'utiliser des meteaux inoxytables du type
or,acier inoxytable,autres.In order to preserve the glue during a
some time before its use it is 30uhai- -table to use inoxtables meters of the type
gold, stainless steel, other.

De meme il est possible de pouvoir réaliser des
élements tridimentionels pouvants ntteidre plusieurs
céntimétres (cm) d'epaisseur,en utilisant une colle
de preference reticulable à l'aide d'un catalyseur
tel que le polyester,ce qui permet des prises en
masse.Similarly, it is possible to achieve
three-dimensional elements that could
microcentres (cm) of thickness, using glue
preferably crosslinkable using a catalyst
such as polyester, which allows for
mass.

Dans ce cas la colle électronique se présente
sous deux formes d'élements à melanger au moment
d'utilisation. In this case the electronic glue is presented
in two forms of elements to mix at the moment
use.
