(FR) PROCEDE DE CONNEXION
Abstract
(EN)
A printed circuit board (7) is electrically connected to an electroluminescent display by applying the circuit board (7) to the display so that metal tracks (8) on the underside of the circuit bard (7) make electrical contact with conductive tracks (6) on the display. While the tracks (6, 8) are in electrical contact and electrically insulating adhesive (10) is applied between the lower surface of the circuit board (7) and the upper surface of the display to bond the circuit board (7) to the display. The thickness of the tracks (6, 8) spaces the circuit board (7) from the display to define a void to receive the adhesive (10). The connection method has the advantage that the operation of the assembled circuit board (7) and display can be tested before the adhesive is applied.
(FR)
L'invention concerne une carte (7) de circuit imprimé électriquement connectée à un affichage électroluminescent par application de ladite carte (7) de circuit imprimé sur l'affichage, de sorte que les tracés métalliques (8) se trouvant sous la carte (7) sont en contact électrique avec des tracés conducteurs (6) de l'affichage. Pendant que les tracés (6, 8) sont en contact électrique, un adhésif électro-conducteur (10) est appliqué entre la surface inférieure de la carte (7) et la surface supérieure de l'affichage afin de relier la carte de circuit (7) audit affichage. L'épaisseur des tracés (6, 8) écarte la carte de circuit (7) de l'affichage afin de définir un vide destiné à recevoir l'adhésif (10). Le procédé de connexion présente l'avantage de contrôler la carte circuit (7) assemblée et l'affichage avant l'application dudit l'adhésif.
