Des exigences plus \u00e9lev\u00e9es en mati\u00e8re de pr\u00e9cision entra\u00eenent g\u00e9n\u00e9ralement des co\u00fbts plus \u00e9lev\u00e9s.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1769046265512\"><strong class=\"schema-faq-question\">Q : Pourquoi l'assemblage de circuits imprim\u00e9s co\u00fbte-t-il parfois plus cher que la fabrication de circuits imprim\u00e9s ?<\/strong> <p class=\"schema-faq-answer\">R : L'assemblage de circuits imprim\u00e9s implique l'approvisionnement en composants, le placement SMT, le soudage, l'inspection et les tests fonctionnels.
