Description

4 Layer High Frequency PCB Built On 2 Cores of 20mil RO4350B with Back Drill for GPS Tracker

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

 

Hello Everyone,

Warm greetings!

This type of 4 Layer Rogers PCB is built on 2 core of 0.508mm (20mil) RO4350B for the application of GPS tracker. This board, we used back drilling technology to achieve the “blind via”. See the stack-up.

Back drilling can reduce noise interference and improve signal integrity. Using back drilling successfully reduced the difficulty of PCB fabrication and avoided the use of buried /blind via process.

 

The specifications of the PCB are as follows:

Base material: RO4350B 20 mil + RO4450B 4 mil

Layer count: 4 layers

Type: Mixed multiplier milled separately

Format: 70mm x 125mm = 1 piece

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

 

Features and benefits

1) Excellent high frequency performance due to low dielectric tolerance and loss;

2) Low thermal coefficient of dielectric constant;

3) Back drilling reducing noise interference;

4) ISO9001, ISO14001, UL certified manufacturing factory;

5) 30000 square meter month capability;

 

Applications

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