4 Layer High Frequency PCB Built On 20mil RO4350B With Back Drilling

Hi,

This is a type of 4 Layer Rogers PCB built on 20mil (0.508mm) RO4350B with Tg 280°C for the application of GPS tracker. Multilayer PCB's on Rogers material have different structure (stack up) from FR-4 multilayer PCB's, because the core of Rogers material is semi-manufactures.

For this 4 layer high frequency PCB, it uses 2 cores of 20mil RO4350B. Usually blind via from layer 1 to layer 3 is hard to be drilled. On the other hand, the back drill technology can solve this problem of signal integrity.

Basic specifications

Base material: RO4350B 20 mil + RO4450B 4 mil

Layer count: 4 layers

Type: Mixed multiplier milled separately

Format: 300mm x 182mm = 5 types = 8 pieces

Surface finish: Immersion gold

Copper weight: Outer layer 35 um/ Inner layer 18 um

Solder mask / Legend: Green / white

Final PCB height: 1.42 mm

Standard: IPC 6012 Class 2

Packing: Each 25 panels are packed for shipment.

Lead time: 12 working days

Shelf life: 6 months

Application

Multiplexer, Video transmission gear, Low noise block, Power divider

Stack up, 4 Layer
