Insulation GuarantyYES

Isoliertes Metallsubstrat (IMS), basierend auf Aluminium mit niedrigem CTE, beschichtet mit einer dielektrischen Schicht mit niedrigem Zugmodul auf einer ED-Kupferfolie.
Der ultradünne LM wurde entwickelt, um die Wärmeabgabe von MPCBs zu reduzieren und gleichzeitig das Verhalten im Wärmezyklustest zu verbessern. Durch die Reduzierung des Zugmoduls des Ultradünnen LM wird das Reißen von Lötstellen erheblich reduziert. Die Zusammensetzung der dielektrischen Schicht wurde entwickelt, um die innere Spannung während der thermischen Wechselbeanspruchung zu minimieren. Die typische Fehlanpassung zwischen Aluminiumbasis und Kupfer wird dank des Verhaltens der dielektrischen Schicht mit niedrigem Modul eingestellt und verringert. Eine eigens entwickelte Polymer-Keramik-Haftschicht mit hoher Wärmeleitfähigkeit und Durchschlagsfestigkeit garantiert die thermische Beständigkeit.
