6-Layer Rogers RO4350B Hybrid PCB

6-Layer Rogers RO4350B Hybrid PCB | High Frequency RF Circuit Board

Product Overview

This is a 6-layer hybrid PCB with Rogers RO4350B + FR-4. Finished dimension: 267.5*110mm, board thickness 1.2mm, surface finish ENIG. Minimum trace width/space: 8mil/8mil, minimum hole size:0.3mm.

Hybrid stack-up with Rogers RO4350B ceramic filled PTFE high-frequency material and FR4. It achieves excellent RF performance while optimizing cost. Low signal attenuation and stable dielectric constant make it ideal for microwave, radar and wireless communication applications. Juehui Circuit has mature manufacturing capability for hybrid high-frequency PCB, supporting prototype and small-batch production.
