class=\"schema-faq-question\">V: Hoeveel stroom kan een printspoor dragen?<\/strong> <p class=\"schema-faq-answer\">A: De stroomcapaciteit hangt af van de spoorbreedte, de koperdikte en de toegestane temperatuurstijging. Een 20 mil spoor met 1 oz koper kan bijvoorbeeld ongeveer 2-3 A dragen onder normale omstandigheden.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1772680390686\"><strong class=\"schema-faq-question\">V: Wat gebeurt er als een printspoor te smal is?<\/strong> <p class=\"schema-faq-answer\">A: Een smal spoor kan oververhit raken, wat kan leiden tot overmatige weerstand, spanningsverlies en mogelijke schade aan het koper.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1772680411563\"><strong class=\"schema-faq-question\">V: Hoe bereken ik de PCB-spoorbreedte?<\/strong> <p class=\"schema-faq-answer\">A: Ontwerpers gebruiken meestal IPC-2221-gebaseerde calculators die rekening houden met stroom, koperdikte en temperatuurstijging.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1772680424687\"><strong class=\"schema-faq-question\">V: Zijn interne printsporen zwakker dan externe?<\/strong> <p class=\"schema-faq-answer\">A: Ja.
