Der Hauptunterschied liegt in dem im Laminat verwendeten Verst\u00e4rkungsmaterial.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unterschiedliche Verst\u00e4rkungsstrukturen f\u00fchren zu unterschiedlichen mechanischen und elektrischen Eigenschaften.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Von den verf\u00fcgbaren Sorten werden CEM-1 und CEM-3 in der Leiterplattenherstellung am h\u00e4ufigsten verwendet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Was ist CEM-1?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CEM-1 besteht aus einem Papierkern, der an den Au\u00dfenfl\u00e4chen mit Lagen aus gewebtem Glasfasergewebe ummantelt ist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Diese Konstruktion bietet eine h\u00f6here mechanische Festigkeit als Laminate auf Papierbasis, w\u00e4hrend die Herstellungskosten relativ niedrig bleiben.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zu den typischen Merkmalen geh\u00f6ren:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>gute elektrische Isolierung<\/li>\n\n\n\n<li>relativ geringe Materialkosten<\/li>\n\n\n\n<li>geeignet f\u00fcr einseitige Leiterplatten<\/li>\n\n\n\n<li>Eingeschr\u00e4nkte Unterst\u00fctzung f\u00fcr durchkontaktierte L\u00f6cher<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Aufgrund seines Aufbaus wird CEM-1 haupts\u00e4chlich f\u00fcr einfache Leiterplatten verwendet.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Was ist CEM-3?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">CEM-3 wird unter Verwendung einer durchgehenden Glasfaserverst\u00e4rkung im gesamten Laminat hergestellt, wodurch es eine Struktur erh\u00e4lt, die der von FR4 \u00e4hnlicher ist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Im Vergleich zu CEM-1 bietet es:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>verbesserte mechanische Festigkeit<\/li>\n\n\n\n<li>bessere Ma\u00dfhaltigkeit<\/li>\n\n\n\n<li>glattere Oberfl\u00e4chenbeschaffenheit<\/li>\n\n\n\n<li>Kompatibilit\u00e4t mit der Herstellung doppelseitiger Leiterplatten<\/li>\n\n\n\n<li>verbesserte Bohrqualit\u00e4t<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Es sieht oft heller aus als herk\u00f6mmliches FR4.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mechanische Leistung<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Die mechanische Festigkeit beeinflusst die Bearbeitungsqualit\u00e4t und die Langzeitbest\u00e4ndigkeit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">CEM-3 bietet im Allgemeinen eine h\u00f6here Steifigkeit und Ma\u00dfhaltigkeit als CEM-1.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dadurch eignet es sich besser f\u00fcr Produkte, bei denen engere Fertigungstoleranzen oder wiederholte

Mittelfrequenzbereich.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allerdings bietet FR4 im Allgemeinen gleichm\u00e4\u00dfigere elektrische Eigenschaften, insbesondere bei mehrschichtigen oder Hochgeschwindigkeits-Leiterplatten.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00fcr Produkte mit geringen elektrischen Anforderungen sind beide CEM-Materialien weiterhin praktikable

Herstellung aus.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">CEM-1<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CEM-1 wird \u00fcblicherweise f\u00fcr folgende Zwecke verwendet:<\/p>\n\n\n\n<ul

class=\"wp-block-paragraph\">Aufgrund seines Papierkerns eignet er sich nur bedingt f\u00fcr komplexere Kartonstrukturen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">CEM-3<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CEM-3 unterst\u00fctzt:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>doppelseitige Platten<\/li>\n\n\n\n<li>durchkontaktierte L\u00f6cher<\/li>\n\n\n\n<li>h\u00f6here Montagequalit\u00e4t<\/li>\n\n\n\n<li>stabilere Fertigungsprozesse<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Aus diesen Gr\u00fcnden wird es h\u00e4ufig gew\u00e4hlt, wenn eine h\u00f6here Zuverl\u00e4ssigkeit erforderlich ist, ohne jedoch vollst\u00e4ndig auf FR4 umzusteigen.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Typische Anwendungen<\/h2>\n\n\n\n<h3

class=\"wp-block-heading\">Kosten\u00fcberlegungen<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Die Materialkosten sind ein Grund daf\u00fcr, dass CEM-Laminate weiterhin verwendet werden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Allgemein:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>CEM-1 ist g\u00fcnstiger als CEM-3.<\/li>\n\n\n\n<li>CEM-3 ist in der Regel kosteng\u00fcnstiger als herk\u00f6mmliches FR4 und bietet gleichzeitig eine bessere Leistung als CEM-1.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Die Gesamtfertigungskosten h\u00e4ngen zudem von der Komplexit\u00e4t der Leiterplatte, dem Produktionsvolumen und den Verarbeitungsanforderungen ab.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Die Wahl zwischen CEM-1, CEM-3 und FR4<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Bei der Materialauswahl sollte mehr als nur der Preis ber\u00fccksichtigt werden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zu den zu bewertenden Fragen geh\u00f6ren:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Ist die Platine einseitig oder doppelseitig?<\/li>\n\n\n\n<li>Sind durchkontaktierte L\u00f6cher

Zuverl\u00e4ssigkeit eine Priorit\u00e4t?<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Bei vielen einfachen Produkten bieten CEM-Materialien eine ausreichende Leistungsf\u00e4higkeit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">F\u00fcr mehrschichtige, hochdichte oder thermisch anspruchsvolle Konstruktionen ist FR4 nach wie vor die erste
