Mixed Laminate Multilayer PCBs
Consisting of multiple laminates and differing dielectric constants, this multilayer (displayed above) is a mixed-dielectric printed circuit board.


Mixed Laminate Multilayer PCBs
Mixed laminate multilayer PCBs are ideal for complex and high-speed circuit designs that require different dielectric constants. They are composed of multiple layers of different laminates, allowing for precise control of impedance, signal integrity, and heat dissipation. The different layers of mixed laminate multilayer PCBs can be interconnected using vias and buried vias, providing a high degree of routing flexibility.
