Introduction

Hi Everyone,
Multilayer Rogers PCBs are constructed using multiple cores combined, distinguishing them from conventional FR-4 multilayer PCBs. The RO4350B family includes eight core thickness options, ranging from 4mil (0.101mm) to 60mil (1.524mm).

Thickness (mil)	Thickness (mm)
4mil	0.101mm
6.6mil	0.168mm
10mil	0.254mm
13.3mil	0.338mm
16.6mil	0.422mm
20mil	0.508mm
30mil	0.762mm
60mil	1.524mm

The stacking of four layers can be achieved in various configurations.

Today, we introduce a Rogers 4-layer PCB built on 6.6mil and 20mil RO4350B for radar sensor applications.

Let’s see first one and stack-up is shown first.

This RF board features a thickness of 1.0mm with a minimum track width of 4mil and a gap of 5mil. It is a high-frequency multilayer PCB using RO4450F as the dielectric prepreg. The board has white silkscreen over green solder mask, with immersion gold plating on pads. Each panel is supplied as a single unit, fabricated to IPC 6012 Class 2 standards using provided Gerber data. Ten boards are packed for shipment.

Stack-Up Details:

Layer 1 to Layer 2: First core of 6.6mil
Layer 3 to Layer 4: Second core of 20mil
Combined with two sheets of RO4450F (1 RO4450F = 4mil

The second one is very similar to previous one, the stack-up explains all.

Features and Benefits:

1.Low Dielectric Constant: Ensures excellent high-frequency performance and minimal signal delay.
2.Surface Planarity: Immersion gold provides superior surface flatness, crucial for BGA packages and CSP mounted components, reducing assembly failures.
3.Comprehensive Testing: All PCBs undergo 100% electrical testing, AOI inspection, thermal stress testing, reliability testing, insulation resistance testing, and ionic contamination testing.
4.Rapid Production: Efficient processes facilitate a quick turnaround, from prototypes to standard production runs.
5.Compliance: UL recognized and adheres to RoHS Directive standards.

Applications:

TV Antenna
Transmitter Combiner
Sound Control Switch Induction
Tower-Mounted Amplifier
RF Module
Power Splitter
Low Noise Block
4G Antenna
