4 Layer High Frequency PCB On 6.6 Mil RO4350B and 10 Mil RO4350B for Radar System

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


Multilayer high frequency PCBs are made from all high frequency material inclusive of prepreg adhesive. For example, a 4-layer Rogers RO4350B PCB is a compound of 2 cores RO4350B substrates. 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 talked is a 4-layer RO4350B high frequency PCB built on 6.6mil and 10mil RO4350B substrate for the application of radar system. This RF board has a thickness of 0.82mm with a minimum 4mil track and 5mil gap. This is a pure high frequency multilayer PCB with RO4450B as dielectric prepreg. Other specifications are white silkscreen over green solder mask, immersion gold plated on pads. Entire board is supplied 1 up per panel. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 50 panels are packed for shipment. Here’s detail of stack-up:
