6 Layer High Frequency PCB Built On 3
Cores of 20mil RO4003C and 4mil RO4450F for Radar Altimeter
(Printed

Hello
everyone.
Warm
greetings!
Today
we talked about is a type of 6 layers high frequency PCB. It’s built on 3 core
of 20mil RO4003C with bondply RO4450F for the application of radar altimeter. The
stack-up is as follows.
As
is known to all, there’re 6 cores in RO4003C family, i.e. 8mil (0.203mm) to
60mil (1.524mm).
|
RO4003C:
|
|
|
8mil
|
0.203mm
|
|
12mil
|
0.305mm
|
|
16mil
|
0.406mm
|
|
20mil
|
0.508mm
|
|
32mil
|
0.813mm
|
|
60mil
|
1.524mm
|
So it’s very interesting that stack-up of 4
layers can be done in many different ways.
Following
is the basic specifications.
Base
material: RO4003C 0.508 mm x 3 sheets, RO4450F 0.102mm x 1 sheet
Layer

Features and benefits :
1) RO4003C
exhibits a stable dielectric constant over a broad frequency range. This makes
it an ideal substrate for broadband applications;
2) Reducing
signal loss in high frequency application meets the development needs of
communication technology;
3) UL,
ISO14001, IATF16949 certified factory;
4) 16000
square meter workshop;
5) More
than 18 years of PCB experience;
Applications:
Satellite
antenna, Power splitter, Radio frequency, Power divider
