Hybrid PCB Built On 8mil 0.203mm RO4003C and 0.2mm FR-4 Multilayer High Frequency PCB Combined RO4003C and FR-4

(PCB’s are custom-made products, the picture and parameters shown are just for reference)

Hello everyone,

Warm greetings!

Today we’ll talk about a type of 4-layer hybrid PCB built on 8mil (0.203mm) RO4003C and FR-4 for the application of attenuator. It's 1.1 mm thick with blue solder mask and immersion silver on pads, 1oz copper on each layer. Generally speaking, this is a type of simple multilayer PCB with hybrid structure. They're fabricated per IPC 6012 Class 2 using supplied Gerber data. Each board is 100% electrical tested before delivery, 25 boards are packed for shipment.

Let’s see the stack-up.

Layer 1 to layer 2 is the RO4003C core (8mil),the core has fixed thickness which is very important to the electrical length of RF lines on the circuit board, then the left materials are FR-4. Boards are all through holes.

Following drawing is 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 build-up;

3) ISO9001, ISO14001, IATF16949, ISO13485, UL Certified;

4) Thermal stress test, reliability test, insulation resistance test and ionic contamination test, AOI test etc.

5) No MOQ required;

6) More than 19+ years of high frequency PCB experience;

7) 16000㎡ workshop; 30000㎡ output capability per month and 8000 types of PCB's per month;

8) Powerful PCB capabilities support your research and development, sales and marketing;
