4 Layer Hybrid PCB Built On 8mil 0.203mm RO4003C and FR-4 for Phased Array Antennas
(PCB’s are custom-made products, the picture and parameters shown are just for reference)
Today we’ll see a type of 4 layer hybrid PCB built on 0.203mm (8mil) RO4003C and FR-4 for the application of attenuator. It's 1.1 mm thick with blue solder mask and immersion silver on pads. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 25 boards are packed for shipment.
Let’s see the stack-up.
Layer 1 to layer 2 is the RO4003C core, then the left are FR-4 material. Boards are through holes.
Let’s see the micro-section.
Features and Benefits
1) RO4003C exhibit a stable dielectric constant over a broad frequency range. This makes it an ideal substrate for broadband applications.
2) Signal integrity performance improvement over the stack-ups with all FR4 board
3) Thermal stress test, reliability test, insulation resistance test and ionic contamination test, AOI test etc.
4) No MOQ
5) Experienced sales persons provide skilled customer services.
Applications
RF transceiver, Power divider, LNB, Attenuator, Directional coupler, Photocoupler
