Hello Everyone,

Warm greetings!

This 4-layer Rogers PCB is constructed with 2 cores of 0.508mm (20mil) RO4350B, specifically designed for GPS tracker applications. The board utilizes back-drilling technology to achieve "blind vias," ensuring optimal performance. Take a look at the stack-up for more details!

Back drilling not only serves to mitigate noise interference and enhance signal integrity but also, by being implemented successfully, it has lessened the complexity of PCB fabrication and precluded the need for the 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

1. Exceptional high - frequency performance, courtesy of low dielectric tolerance and loss.

2. Low thermal coefficient of dielectric constant.

3. Back drilling cuts down noise interference.

4. Manufactured in a factory with ISO9001, ISO14001, UL certifications.

5. Monthly production capacity of 30,000 square meters.
