Mehrschichtplatten

Multilayer circuit boards are composite boards with three or more conductive layers. Each layer is isolated by an insulating dielectric layer and electrically connected by plated through-holes. The outer layer is a double-sided trace layer, while the inner conductive layers are integrated within an insulating board. Single- or double-layer circuit boards are stacked using optical positioning and layer-by-layer lamination to form a multilayer substrate. The stacked structure is crucial; the thickness of each dielectric layer directly affects the circuit impedance characteristics, signal integrity, and heat dissipation performance.

Mehrschichtplattenals eine Art von Leiterplatte, werden in erster Linie basierend auf Materialeigenschaften eingestuft:

Multilayer circuit boards can be classified into standard and special types based on the substrate’s mechanical and electrical properties.

Standardtypen mainly use an FR-4 epoxy glass cloth substrate, which has good mechanical strength and general electrical properties, making it suitable for most general electronic devices.

Sondertypen umfassen Hochfrequenzplatten (wie solche, die Polytetrafluorethylen verwenden, geeignet für Funkfrequenz- und Mikrowellenkommunikation), Metallsubstrate (wie Aluminiumsubstrate, die eine ausgezeichnete Wärmeabfuhr aufweisen und in leistungsstarken Stromversorgungen verwendet werden) und Keramiksubstrate (die eine hohe Wärmebeständigkeit und Stabilität aufweisen, geeignet für Hochtemperaturumgebungen) usw.

Many products use multilayer PCBs, including computers, medical equipment, in-car systems, GPS and satellite systems, and industrial control systems. It is the core carrier of modern high-end, complex electronic devices.
