Hello, everyone!
Warm greetings to you all.
Today, we're diving into the world of 6 - layer hybrid PCBs constructed using RO4350B and FR - 4 materials. Let's start by taking a look at the first one. |
|
|
|
|
|
 |
|
|
|
|
|
This PCB is designed for radar antenna applications, featuring a hybrid construction with RO4350B cores on both the top and bottom sides. Plated through-holes (PTH) ensure reliable interlayer connections across all layers. Based on the stack-up design, each dielectric layer exceeds 0.2mm in thickness, contributing to an overall PCB thickness of 1.9mm. The pads and holes are coated with immersion gold for enhanced durability and performance. Manufactured in compliance with IPC 6012 Class 2 standards, the boards are produced using provided Gerber files. For shipping convenience, the PCBs are packed in sets of 25 panels per shipment. |

 |
|
|
|
|
|
This design is more intricate compared to the previous version. While it retains the 10mil RO4350B core, the key distinction lies in the incorporation of three distinct types of blind vias. The detailed specifications are outlined below: |
|
|
|
|
|
Base material: RO4350B 10mil + FR4
Layer count: 6 layers
Type: Blind via L1-L2, L1-L3, L1-L4
Format: 82mm x 95mm = 1 type = 1 piece
Surface finish: Immersion gold
Copper weight: Outer layer 35 μm/ Inner layer 35 μm
Solder mask / Legend: No
Final PCB height: 1.4 mm
Standard: IPC 6012 Class 2
Packing: 20 panels are packed for shipment.
Lead time: 20 working days
Shelf life: 6 months |
|
|
|
|
|
A comparable product features inner layers constructed with half-ounce copper, resulting in a finished PCB thickness of 1.0mm. Below are the detailed stack-up and microsection analysis. |

RO4350B hybrid PCBs offer numerous benefits |
|
|
1) Signal integrity performance improved over the stack-ups with all FR4 board;
2) Cost reduced over stack-ups with all low loss material;
3) Engineering design prevents problems from occurring in pre-production;
4) ISO9000, ISO14001, IATF16949, UL Certified factory
5) IPC Class 2 / IPC Class 3; |
|
|
|
|
|
Applications |
|
|
These products have a diverse range of applications, which are as follows: radar data acquisition converters, microstrip antennas, tower - mounted boosters, modular oscilloscopes, attenuators, 5G antennas, and so on.
