Blind Via Radar PCB

 

4 Layer High Frequency PCB Built On 6.6mil and 20mil RO4350B with Blind Via for Radar Sensor

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

 

Multilayer Rogers PCBs are made based on several core combined, which are different from FR-4 multilayer PCBs. As is known to all, there’re 8 cores in RO4350B family, i.e. 4mil (0.101mm) to 60mil (1.524mm).

 

RO4350B
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

 

So it’s very interesting that stack-up of 4 layers can be done in many different ways.

 

Today, we are going to introduce Rogers 4-layer PCBs built on 6.6mil and 20mil RO4350B.

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

 

RO4350B 4 Layer Blind Via Immersion Gold PCB For Radar Sensor 0

 

Layer 1 to layer 2 is the first core of 6.6mil, layer 3 to layer 4 is the second core of 20mil, they are combined through 2 sheet of RO4450F (1 RO4450F=4mil). This board is used for radar sensor, 1.0mm thick, pads with immersion gold. It contains blind via from top layer to inner 1. Since it's asymmetric buildup, 1.2% warpage is allowed. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards are packed for shipment.

 

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

Features and benefits

1) The dielectric constant (DK) is low and stable, so the signal transmission is good without delay.

2) Immersion gold has excellent surface planarity, particularly helpful for PCBs with BGA packages or even CSP mounted components to reduce failure rate during assembly and soldering.

3) 100% tests inclusive of electrical test and AOI inspection, thermal stress test, reliability test, insulation resistance test and ionic contamination test,

4) Fast and flexible to save the time of production from prototype to standard production

5) UL recognized and RoHS Directive-compliant

 

Applications

TV antenna, Transmitter combiner, Sound control switch induction, Tower Mounted Amplifier, RF module, Power splitter, Low Noise Block, 4G antenna
