A conductive adhesive, such as an anisotropic conductive adhesive, comprising a population of conductive particles and a population of signal particles in an adhesive; wherein both the conductive particle population and the signal particle population have an average particle diameter of &#x3c;200 &#x3bc;m with a coefficient of variance of &#x3c;10%; wherein the signal particles are arranged to provide an indication when they are deformed to a pre-determined height; and wherein the conductive particles are arranged such that they will not fail, e.g. crack or fracture, when deformed to a height larger than or equal to the pre-determined height at which the signal particles are arranged to provide the indication.

Conductive adhesives

A process for the preparation of an activated polymer particle comprising contacting a polymer particle with at least one polyamine, wherein said polyamine has three or more amino groups, to form a surface treated polymer particle; and applying a catalyst to the surface treated polymer particle to form an activated polymer particle. In some examples, the process can further comprise applying a metal coating to said activated polymer particle to form a metal coated polymer particle.

Process for the surface modification of a polymer particle

An isotropic conductive adhesive having silver coated polymer beads within an adhesive matrix and a method of forming an isotropic conductive adhesive are disclosed. The mean average diameter of the polymer cores of the beads is less than 30 &#x3bc;m, and the silver coating comprises interlinked silver deposits grown from dispersed nucleation sites scattered across the surface of the beads.

Polybranched organic/inorganic hybrid polymer and method for its manufacture. The hybrid polymer has the form of an inorganic core carrying organic branches. The core is first prepared by controlled hydrolysis and condensation of a silane with a structure: X&#x2014;B&#x2014;Si(&#x2014;Y)in which X&#x2550;NRR, while R, Rare chosen among hydrogen, alkyl and aryl, or R, Rare chosen among condensation products, addition products of one or more type of chemical substances such as acids, alcohols, phenols, amines, aldehydes or epoxides. B is a linkage group chosen among alkylene and arylene which may include oxygen, nitrogen, sulphur, phosphorous, silicon and boron. Y is chosen among hydrolyzable residues such as alkoxy, carboxyl, and halogen. The organic branches are developed by substituting N&#x2014;H hydrogen atoms in the X&#x2014;B group by reactions that are typical for primary and secondary amines, and/or by adding an acid that causes an addition to the N atoms of the X&#x2014;B group in the core. Specific uses of the hybrid polymers are also indicated.
