Pastille de contact simple face pour dôme à souder

 **REMARQUE**

  • Il est suggéré de percer un trou à travers la carte pour la ventilation si aucun autre moyen n’est utilisé.
  • Snaptron recommande que la zone de circuit placée sous le dôme ne comporte pas de masque de soudure. La zone à accès interdit commence à l’angle extérieur de la pastille de circuit sur laquelle est placé le dôme et inclut la zone située à l’intérieur des pastilles.
