6 Layer FR4 PCB Board


10mil FR4 PCB Board


FR4 6 Layer PCB


6 Layer Mixed PCB Built On 10mil 0.254mm RO4350B and FR-4 with Blind Via for Digital Radio Antennas

(Printed circuit boards are custom-made products, the picture and parameters shown are just for reference)


Hello everyone,

Warm greetings!

Today we’re talking about 6-layer hybrid PCB built on RO4350B and FR-4. Let’s see first one.

6 Layer FR4 PCB Board 0


It’s for the application of radar antenna. Two cores of RO4350B on top side and bottom side, plated through holes connect each layer. Viewing from the stack-up, each dielectric material is more than 0.2mmm thick which result in whole PCB thickness to 1.9mm thick. Pads and holes are immersion gold plated. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 panels are packed for shipment.

Let’s see second one.


6 Layer FR4 PCB Board 2


This type is more complex than the first one. The 10mil RO4350B core is the same. The main difference is that it contains 3 types blind via. The specifications are as follows:


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


There’s a very similar products whose inner-layers are using half ounce copper. Finished PCB thickness is 1.0mm. Following is the stack-up and microsecton.

Therere many advantages of RO4350B hybrid PCBs.

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;


The applications are wide, listed below: Radar data acquisition converter, miscrostrip antenna, tower-mounted booster, modular oscilloscope, attenuator and 5G antenna etc.
