New Hybrid PCB: 4 Layer PCB Mixing 0.254mm (10 Mil) RO4350B And 0.36mm FR-4

2018.12.27 15


This is a type of 4 Layer PCB mixing 0.254mm (10 mil) RO4350B and 0.36mm FR-4 for the application of Variable Frequency Drive.

The multilayer mixed-press printed circuit board comprises an insulating dielectric layer and a signal layer. And the dielectric layer and the signal layer are alternately stacked. The signal layer comprises a signal layer for transmitting a high speed signal and a signal layer for transmitting a low speed signal. The high frequency characteristic of the RO4350B substrate is better than that of FR-4 substrate, and the dielectric loss caused by the transmission signal is smaller than that of FR-4 substrate. The invention of multilayer mixed-press can not only ensure the high frequency performance of the printed circuit board, but also reduce the manufacturing cost of the multilayer PCB made of full high frequency material.
