6 Layer Copper Inlay Mixed laminated PCB
2025-03-15
The 6Layer Copper Inlay Mixed Laminate PCB is engineered for high-frequency, high-reliability electronics, combining RO4035B (ceramic-filled high-frequency material) and TU768 (low-loss thermoset resin) through hybrid lamination. This achieves exceptional dielectric performance (Dk=3.5±0.05 @10GHz) and mechanical stability. Key features include copper inlay structures, resin-filled vias, and precision step slots, ideal for complex RF circuits and high-speed digital signal transmission.
