Title (EN) COVER TAPE FOR PACKAGING ELECTRONIC COMPONENTS
(FR) RUBAN DE COUVERTURE POUR L'ENCAPSULATION DE COMPOSANTS ELECTRONIQUES
Abstract:
(EN) For solving a problem of large dependency of peel-off strength upon sealing conditions, a problem of change of various properties with the lapse of time under storing circumstances, a delamination problem, an agglomerate problem and a transparency problem, there is provided a cover tape for packaging electronic components which has a stable peel-off strength and is composed of an outer layer consisting of a biaxially oriented film of any one of polyester, polypropylene and nylon; an intermediate layer consisting of a mixture comprising polyethylene as the main component; and a heat sealant layer consisting of a mixture of a thermoplastic resin and a filler.
(FR) L'invention porte sur un ruban de couverture pour l'encapsulation de composants électroniques résolvant les problèmes de la dépendance de la force d'arrachement sur l'étanchéité, de l'altération de différentes propriétés en fonction du temps et des conditions de stockage, de déstratification, de l'agglomération et de la transparence. Ledit ruban, qui présente une force d'arrachement stable, comprend une couche extérieure constituée d'un film de polyester de polypropylène ou de nylon, à orientation biaxiale, une couche intermédiaire constituée d'un mélange principalement à base de polyéthylène, et une couche thermoscellable faite d'un mélange d'une résine thermoplastique et d'une charge.
