Abstract: front page image
(EN)Disclosed herein are anisotropic conductive particles contained in anisotropic conductive adhesive films which are used in the mounting field of circuit boards. The conductive particles exhibit superior electrical reliability. Further disclosed are polymer particles having good compressive deformability and recoverability from deformation without being ruptured when an adhesive film containing the conductive particles is interposed and compressed between connection substrates, thereby achieving a sufficient contact area between the particles and the connection substrates. Since the polymer particles have a spherical shape, a uniform particle diameter, and a narrow particle diameter distribution, they show enhanced conducting properties.
(FR)L'invention concerne des particules conductrices anisotropes contenues dans des films adhésifs conducteurs anisotropes utilisés dans le domaine du montage de cartes à circuit imprimé. Les particules conductrices présentent une fiabilité électrique supérieure. L'invention concerne de plus des particules polymères présentant une bonne déformabilité à la compression et une bonne capacité de récupération après déformation sans rupture, lorsqu'un film adhésif contenant les particules conductrices est placé et comprimé entre des substrats de liaison, ce qui permet de former une surface de contact suffisante entre les particules et les substrats de liaison. Ces particules polymères, de forme sphérique, qui présentent un diamètre des particules uniforme et une distribution étroite du diamètre des particules, possèdent des propriétés conductrices améliorées.
