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)

Hi Everyone,

Multilayer high frequency PCBs are made from all high frequency material inclusive of prepreg adhesive. For example, a 4-layer RO4350B PCB is a compound of 2 cores of RO4350B substrates. As is known to all, there’re 8 cores in RO4350B family, i.e. 4mil (0.101mm) to 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:



Features and benefits
1) Excellent high frequency performance due to low dielectric tolerance and loss;
2) Good high temperature and low temperature resistance(-192℃-260℃);
3) Eligible products rate of first production: >95%
4) Delivery on time: >98%
5) Customer complaint rate: <1%




Applications
Modular oscilloscope, Vario-coupler, Tower-mounted booster, Power amplifier
Splitter, Acoustic detection sensors, RF Switches, Trunk amplifier
