Hello everyone,

Warm greetings!

The hybrid PCB can be a mixture of FR-4 and high frequency material, and a mixture of high frequency material with different dielectric constant (DK), for example RT/duroid 5880 and RO4350B etc.

Today we’ll talk about a type of mixed high frequency PCB made on 13.3mil (0.338mm) RO4350B and 31mil (0.787mm) RT/duroid 5880. It’s for the application of multi-coupler antenna.

This is a 3-layer board that one layer is etched off.

The basic specifications are as follows:

Base material: RO4350B 13.3mil (0.338mm) + RT/duroid 5880 31 mil (0.787mm)

Dielectric constant: 3.48+/-0.05

Layer count: 3 layers

Via type: Through holes, blind vias

Format: 160mm x 90mm = 1 type = 1 piece

Surface finish: Immersion gold

Copper weight: Outer layer 35μm | Inner layer 35μm

Solder mask / Legend: Green / White

Final PCB height: 1.3 mm

Standard: IPC 6012 Class 2
