6 Layer High Frequency PCB Built On 3 Cores of 20mil RO4003C and 4mil RO4450F for Radar Altimeter
(Printed circuit boards are custom-made products, the picture and
parameters shown are just for reference)
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 count: 6 layers
Type: 1 PCB up per panel with v-cut
Format: 129mm x 75mm = 1 type = 1 piece
Surface finish: Immersion gold
Copper weight: Outer layer 35 μm/ Inner layer 35 μm
Solder mask / Legend: Green / White
Final PCB height: 1.94 mm
Standard: IPC 6012 Class 2
Packing: 20 panels are packed for shipment.
Lead time: 10 working days
Shelf life: 6 months
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 17 years of PCB experience;
Applications
Satellite antenna, Power splitter, Radio frequency, Power divider
