Hello, everyone!
Today, we'll be discussing a 4-layer high-frequency PCB that combines 4mil RO4350B and FR-4 materials. The 4-layer configuration of this PCB was chosen for its simplicity and cost-effectiveness, which is crucial for entering new markets.
Now, let's start by examining the initial build-up process. |

Between the first and second layers, as well as the third and fourth layers, we use the Rogers core, specifically 4mil (0.102mm) RO4350B. This core has a fixed thickness, which plays a crucial role in determining the electrical length of the RF lines on the circuit board. Sandwiched in the middle is the FR - 4 epoxy glass dielectric material. It serves to bond the cores on both the top and bottom sides. The inner layer of the PCB has a copper weight of 0.5 ounces, while the outer layer has a copper weight of 1 ounce.

The advantages of RO4350B hybrid PCBs: |
|
|
1. Stable Dielectric Constant:
RO4350B maintains a consistent dielectric constant across a wide frequency range, making it an excellent choice for broadband applications.
2. Enhanced Signal Integrity:
It outperforms stack-ups using only FR4 materials, ensuring superior signal performance.
3. Cost Efficiency:
By combining RO4350B with other materials, it offers a more cost-effective solution compared to all low-loss material stack-ups.
4.Reduced High-Frequency Signal Loss:
It minimizes signal loss at high frequencies, ensuring reliable performance in demanding applications.
5. Expert Manufacturing Support:
Leverage our robust capabilities, from prototyping to mass production, backed by IATF 16949 (2016), ISO14001 (2015), ISO9001 (2015), and UL certifications, guaranteeing top-tier quality for your PCBs. |
