Title (EN) MULTI-LAYERED PRODUCT FOR PRINTED CIRCUIT BOARDS, AND A PROCESS FOR CONTINUOUS MANUFACTURE OF SAME
(FR) PRODUIT MULTICOUCHE POUR CARTES IMPRIMEES, ET SON PROCEDE DE FABRICATION EN CONTINU
Abstract:
(EN) The invention provides a low energy loss, multi-layered polypropylene/metal foil product useful for further processing into printed circuit boards and antenna boards for microwave circuitry. A continuous process for manufacturing the product comprises the steps of: providing metal foil; optionally, extrusion coating molten polypropylene upon the metal foil to obtain a foil coated with a polypropylene foundation layer; unwinding the foil from an unwinding station (10) to an oven (30) before casting a molten polypropylene tie-layer upon the metal foil or the coated foil using extrusion lamination machinery such as a slot die (40) extruder (50); laminating a polypropylene sheet from unwinding station (18) on the tie-layer using compression between rollers (14),(16) in the heated nip area (12) to ensure fusing of the polypropylene layers; and rewinding the multi-layered product on a rewinding station (18). In the process, heat may be applied in one of several ways to induce fusing.
(FR) L'invention concerne un produit multicouche polypropylène/feuille métallique que l'on peut traiter pour obtenir des cartes imprimées et des cartes antennes destinées à des circuits à micro-ondes. L'invention concerne un procédé de fabrication en continu de ce produit, qui consiste à fournir une feuille métallique; éventuellement, à revêtir par extrusion sur ladite feuille métallique un polypropylène fondu, pour obtenir une feuille revêtue d'une couche de fond en polypropylène; à mouler une couche de liaison en polypropylène sur ladite feuille métallique ou sur ladite feuille métallique revêtue; et à laminer une feuille en polypropylène sur ladite couche de liaison. Lors du processus, la chaleur est appliquée de façon à induire la fusion des couches du produit multicouche.
