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).

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
