Title (EN) ULTRA-THIN, REMOVABLE, CATALYTIC FILM FOR LASER DIRECT STRUCTURING (LDS) ON A BLACK OR OPAQUE SUBSTRATE AND THE PROCESS THEREBY
(FR) FILM CATALYTIQUE ULTRA-MINCE AMOVIBLE POUR STRUCTURATION DIRECTE AU LASER (LDS) SUR UN SUBSTRAT NOIR OU OPAQUE ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) A process of forming an article utilizes an ultra-thin, removable, catalytic film for Laser Direct Structuring (LDS). The process includes forming a film from a laser-activatable material, the film exhibiting thickness of less than 100μm; applying the film to a black or opaque substrate to form a film-substrate element; applying a laser to the film-substrate element; removing a portion of the film from the film-substrate element; and applying metal plating to a portion of the black or opaque substrate. Removal of the film from the film-substrate element may follow metal plating of the black or opaque substrate. An article formed by the process may be useful in a computer device, electromagnetic interference device, printed circuit, Wi-Fi device, Bluetooth device, GPS device, cellular antenna device, smart phone device, automotive device, medical device, sensor device, RF antenna device, LED device, RFID device, or a component of a cell phone antenna.
(FR) L'invention concerne un procédé de formation d'un article qui utilise un film catalytique ultra-mince amovible pour la structuration directe au laser (LDS). Le procédé comprend la formation d'un film à partir d'un matériau activable par laser, le film présentant une épaisseur inférieure à 100 µm ; l'application du film sur un substrat noir ou opaque afin de former un élément de substrat de film ; l'application d'un laser à l'élément de substrat de film ; le retrait d'une portion du film de l'élément de substrat de film ; et l'application d'un placage métallique sur une portion du substrat noir ou opaque. Le retrait du film de l'élément de substrat de film peut suivre le placage métallique du substrat noir ou opaque. Un article formé par le procédé peut être utile dans un dispositif informatique, un dispositif de protection contre le brouillage électromagnétique, un circuit imprimé, un dispositif Wi-Fi, un dispositif Bluetooth, un dispositif GPS, un dispositif à antenne cellulaire, un dispositif de téléphone intelligent, un dispositif automobile, un dispositif médical, un dispositif capteur, un dispositif à antenne RF, un dispositif à LED, un dispositif RFID ou un composant d'une antenne de téléphone cellulaire.
