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!

We are excited to introduce a specialized 4-Layer Rogers PCB designed using two cores of 0.508mm (20mil)

RO4350B for a GPS tracker application. This board incorporates back drilling technology to achieve "blind vias"

effectively, enhancing signal integrity and minimizing noise interference. Please refer to the stack-up below for

details.

Back drilling plays a crucial role in reducing noise interference and improving signal integrity. By successfully

implementing back drilling, we have simplified the PCB fabrication process and eliminated the need for buried

/blind via techniques.

Specifications:

• 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 shipment contains 25 panels
• Lead Time: 12 working days
• Shelf Life: 6 months

Features and Benefits:

1. Excellent High-Frequency Performance: Achieved through low dielectric tolerance and loss.
2. Low Thermal Coefficient of Dielectric Constant: Ensures stability across varying temperatures.
3. Noise Interference Reduction: Back drilling enhances signal quality by minimizing noise.
4. Certifications: ISO9001, ISO14001, and UL certified manufacturing facility.
5. Production Capability: Capable of producing 30,000 square meters per month.
   

Applications:

• Multiplexer
• Video Transmission Gear
• Low Noise Block
• Power Divider

This PCB design offers exceptional high-frequency performance, thermal stability, noise reduction

capabilities, and is manufactured in compliance with industry-leading standards. Its versatile applications

make it an ideal choice for various electronic devices requiring reliable signal transmission and interference

mitigation.
