Title (EN) MULTI-LAYER COVER TAPE CONSTRUCTIONS WITH GRAPHITE COATINGS
(FR) STRUCTURES DE RUBAN DE RECOUVREMENT MULTICOUCHE DOTÉES DE REVÊTEMENTS EN GRAPHITE
Abstract:
(EN) Multi-layer cover tape constructions include a polymeric substrate with a low adhesion backsize coating layer on one surface and an adhesive layer on the other surface, with a conductive film construction adhered to a portion of the adhesive layer such that portions of the adhesive remain exposed. The conductive film construction includes a polymeric substrate with an exposed layer of abrasion-resistant, electrically conductive nano-scale graphite coated by buff coating. Other multi-layer cover tape constructions include a polymeric substrate with a low adhesion backsize coating layer on one surface, and an exposed layer of abrasion-resistant, electrically conductive nano-scale graphite particles coated on the other surface. Stripes of adhesive are present on a portion of the electrically conductive coating such that portions of the electrically conductive coating remain exposed between the adhesive stripes. Carrier tapes include a plurality of indented segments for accommodating electronic components and are releasably sealed by a cover tape.
(FR) L'invention porte sur des structures de ruban de recouvrement multicouche comprenant un substrat polymère doté d'une couche de revêtement d'envers de faible adhérence sur une surface et d'une couche adhésive sur l'autre surface, dotées d'une structure de film conducteur collée à une partie de la couche adhésive de façon telle que des parties de l'adhésif restent exposées. La structure de film conducteur comprend un substrat polymère doté d'une couche exposée de graphite de dimension nanométrique électroconducteur et résistant à l'abrasion appliqué en revêtement par revêtement par polissage. D'autres structures de ruban de recouvrement multicouche comprennent un substrat polymère doté d'une couche de revêtement d'envers de faible adhérence sur une surface et d'une couche exposée de particules de graphite de dimension nanométrique électroconductrices et résistantes à l'abrasion appliquées en revêtement sur l'autre surface. Des bandes d'adhésif sont présentes sur une partie du revêtement électroconducteur de façon telle que des parties du revêtement électroconducteur restent exposées entre les bandes adhésives. Des rubans de support comprennent une pluralité de segments en retrait permettant de loger des composants électroniques et sont hermétiquement fermés de manière amovible par un ruban de recouvrement.
