Dans le monde complexe de la conception et de la fabrication de circuits imprim\u00e9s, chaque d\u00e9tail compte. L'un de ces d\u00e9tails, souvent \u00e9tudi\u00e9 avec soin, est la tol\u00e9rance des trous perc\u00e9s dans la carte. Mais comment exprimer ces tol\u00e9rances sur une table de per\u00e7age pour garantir le respect des normes\u00a0? Nous avons r\u00e9cemment re\u00e7u cette question de la part d'un de nos clients et souhaitons publier ce contenu p\u00e9dagogique pour aider les autres acteurs de la conception et de la fabrication de circuits imprim\u00e9s confront\u00e9s \u00e0 des questions similaires. <\/p>\n

Question\u00a0: Comment dois-je exprimer la tol\u00e9rance du trou sur une table de per\u00e7age si je souhaite une tol\u00e9rance standard\u00a0?<\/p>\n

R\u00e9ponse\u00a0: Sauf indication contraire, les dimensions typiques des trous finis d'un circuit imprim\u00e9 sont exprim\u00e9es en trous finis. La tol\u00e9rance typique pour les trous des composants plaqu\u00e9s est de +\/- 0,003\u00a0pouce et celle des connecteurs \u00e0 insertion forc\u00e9e peut \u00eatre de +\/- 0,002\u00a0pouce. Les vias doivent \u00eatre sp\u00e9cifi\u00e9s avec une tol\u00e9rance de +0,002\/- de la taille nominale du trou. Cela permet au fabricant de s\u00e9lectionner le diam\u00e8tre de per\u00e7age qui produira le rendement le plus \u00e9lev\u00e9 et le plus de chances de respecter les exigences de la bague annulaire sp\u00e9cifi\u00e9e. La taille des trous non plaqu\u00e9s doit permettre une tol\u00e9rance de +\/- 0,003\u00a0pouce, mais peut \u00eatre r\u00e9duite \u00e0 +\/- 0,002\u00a0pouce. <\/p>\n

Si vous avez des questions li\u00e9es \u00e0 l'ing\u00e9nierie ou \u00e0 la fabrication auxquelles vous souhaitez obtenir des r\u00e9ponses, n'h\u00e9sitez pas \u00e0 envoyer un e-mail \u00e0 notre \u00e9quipe d'experts pour obtenir de l'aide.<\/p>\n","protected":false},"excerpt":{"rendered":"
