class=\"schema-faq-section\" id=\"faq-question-1766477432510\"><strong class=\"schema-faq-question\">F: Was ist der Unterschied zwischen stromloser und elektrolytischer Verkupferung?<\/strong> <p class=\"schema-faq-answer\">A: Bei der stromlosen Beschichtung wird eine erste leitf\u00e4hige Schicht erzeugt, w\u00e4hrend bei der elektrolytischen Beschichtung die Kupferdicke durch elektrischen Strom erh\u00f6ht wird.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766477464053\"><strong class=\"schema-faq-question\">F: Wie dick sollte die Durchkupferung sein?<\/strong> <p class=\"schema-faq-answer\">A: Die Dicke des Via-Kupfers h\u00e4ngt von den Design- und Zuverl\u00e4ssigkeitsanforderungen ab, muss aber den IPC-Standards f\u00fcr langfristige Leistung entsprechen.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766477547505\"><strong class=\"schema-faq-question\">F: Wodurch entstehen Hohlr\u00e4ume in der Kupferbeschichtung von Leiterplatten?<\/strong> <p class=\"schema-faq-answer\">A: Fehlstellen werden in der Regel durch schlechte Lochreinigung oder unvollst\u00e4ndige stromlose Kupferabdeckung verursacht.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1766477570852\"><strong class=\"schema-faq-question\">F: Wie wirkt sich die Kupferbeschichtung auf die Zuverl\u00e4ssigkeit von Leiterplatten aus?<\/strong> <p class=\"schema-faq-answer\">A: Eine ordnungsgem\u00e4\u00dfe Verkupferung verbessert die Widerstandsf\u00e4higkeit gegen thermische Belastung, mechanische Erm\u00fcdung und
