Greetings, everyone.
Today, our topic is a 4-layer high-frequency PCB fabricated using 10mil RO4350B in combination with FR-4. A 4-layer design was selected for this board as it offers a good balance between simplicity and cost control, making it an ideal choice for exploring new market opportunities.
First off, let's have a look at how the build-up begins. |
|
|
|
|
|
|
|
|
|
|
|
The 1st to 2nd layers consist of a 10mil RO4350B core material, whose fixed thickness is critical for maintaining the electrical length of RF lines on the circuit board. The remaining layers are made of FR-4 materials, bonded together using semi-cured sheets. The inner layers feature 0.5-ounce copper, while the outer layers use 1-ounce copper.

|
Plated through holes (PTH) are used to interconnect all layers, with pads and vias finished in immersion gold for enhanced reliability.
The second board features a unique "hole" design within the structure. Let’s first examine the build-up details. |
|
 |
|
|
|
The 1st and 2nd layers are built on a 10mil core, while the depth-control drill is precisely positioned on the FR-4 side. The entire board has a compact thickness of just 0.7mm. |
|
|
|
 |
|
|
|
The 10mil RO4350B hybrid PCB has a broad range of applications, including preamplifiers, radar sensors, digital transmitters, and splitter modules; GPS antennas, communication relays, analog transmitters, and 4G antennas; as well as RF transmitters, WiFi amplifiers, RFID systems, and attenuators. |
|
|
|
The advantages of 10mil RO4350B hybrid PCBs: |
|
|
1. Stable Dielectric Constant: RO4350B maintains a consistent dielectric constant across a wide frequency range, making it perfect for broadband applications.
2. Enhanced Signal Integrity: It outperforms stack-ups using only FR4 materials, ensuring superior signal performance.
3. Cost Efficiency: It offers a more economical solution compared to stack-ups made entirely of low-loss materials.
4. Expert Manufacturing Support: From prototyping to mass production, our IATF 16949 (2016), ISO14001 (2015), ISO9001 (2015), and UL-certified facilities ensure top-quality PCBs tailored to your needs. |
