Abstract

Selon l'invention, une pâte électriquement conductrice 114 est disposée respectivement entre les faces arrières des réflecteurs 10 et 1 2 et le conducteur de masse 116 du circuit imprimé. De préférence, cette pâte contient des paillettes d'argent, des perles de verre, de l'acétate de butyle cellulosique et un liant acrylique. Des moyens sont par ailleurs prévus pour éviter que cette pâte ne court-circuite deux conducteurs imprimés sur la carte 43. Application : dispositif du type << Flip-Flash >> à dix lampes à éclair.
