Title (EN) EXTRUDED CORE LAMINATES FOR CIRCUIT BOARDS
(FR) STRATIFIES A NOYAU EXTRUDE POUR PLAQUETTES DE CIRCUIT
Abstract:
(EN) A method for fabrication of a circuit board laminate (10) in a continuous process employs an extruded laminate core (12). Streams of a fibrous material, microspheres or fused silica, a catalyst and a thermosetting resin are added to an extruder and the core extruded as a film; outer layers (18, 19) can be applied to the extruded core.
(FR) L'invention concerne un procédé de fabrication d'un stratifié (10) pour plaquettes de circuit, conçu pour un processus continu et utilisant un noyau (12) extrudé de laminé. On ajoute dans l'extrudeuse des jets de matière fibreuse, des microsphères ou de la silice fondue, un catalyseur ou une résine thermodurcissable, et le noyau est extrudé en forme de film. Des couches externes (18, 19) peuvent être appliquées au noyau extrudé.
