4 Layer High Frequency PCB Built On 2 Cores of 20mil RO4350B with Back Drill for GPS Tracker
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;
We can see their applications in multiplexer, video transmission gear, low noise block, power divider etc.
