Multilayer Hybrid PCB on 0.305mm RO4003C and High Tg FR4 Substrate with ENIG

Introducing our newly shipped PCB, a high-quality product that combines the exceptional performance of RO4003C and FR-4 (IT-180A) materials. This 6-layer rigid PCB is designed to meet the stringent requirements of various applications, providing reliable and efficient performance. Let's delve into the details of this advanced PCB:

1. RO4003C Profile:
The PCB utilizes the Rogers RO4003C Hydrocarbon Ceramic woven glass material. With a Dielectric Constant (Dk) of 3.38 at 10 GHz and a Dissipation Factor of 0.0027 at 10 GHz, it ensures reliable signal integrity in high-frequency applications. The RO4003C material has a Tg (Glass Transition Temperature) greater than 280 °C and a Td (Thermal Decomposition Temperature) greater than 425°C, ensuring excellent thermal stability.

1.2 FR-4 (IT-180A) Profile:
This hybrid PCB also incorporates the IT-180A FR-4 material by ITEQ. This high-Tg (175℃ by DSC) material offers low CTE (Coefficient of Thermal Expansion) and high thermal reliability. With a Dielectric Constant (Dk) of 4.4 at 1 GHz and a Dissipation Factor of 0.015 at 1 GHz, it provides reliable electrical performance. The IT-180A material has a Tg greater than 175 °C, ensuring stability under high-temperature conditions. It also exhibits excellent CAF (Conductive Anodic Filament) resistance, lead-free compatibility, and exceptional mechanical processability.

2. Features and Attentions:
The RO4003C laminates offer tight control on dielectric constant (Dk) and low loss, providing excellent signal integrity. They are cost-effective compared to conventional microwave laminates and utilize the same processing method as standard epoxy/glass laminates. However, it's important to note that RO4003C materials are non-brominated and are not UL 94 V-0 rated. The IT-180A material, on the other hand, offers exceptional CAF resistance, lead-free compatibility, and through-hole reliability. It also exhibits high heat resistance and excellent mechanical processability.

3. Stackup:
This 6-layer rigid PCB features a well-designed stackup for optimal performance. The copper layers are 35 μm (1oz) thick on both sides. The PCB consists of two Rogers 4003C cores, each with a thickness of 12mil (0.305mm), and a core IT-180A FR-4 layer. Prepreg layers with a thickness of 0.1mm are used for insulation between copper layers.

4. Construction Details:
The board dimensions of this PCB are 57mm x 57mm, providing a compact and efficient form factor. The minimum trace/space is 4/5 mils, allowing for precise routing of high-density circuits. The minimum hole size is 0.3mm, and all vias are filled and capped for enhanced reliability. The finished board thickness is 1.1mm, with a finished copper weight of 1oz (1.4 mils) on each layer. The via plating thickness is 25 μm, ensuring strong and reliable electrical connections. The surface finish is Immersion Gold (ENIG), providing excellent solderability and corrosion resistance. The PCB features white top and bottom silkscreens, as well as a Matt Blue top and bottom solder mask. The top traces are designed to have a 7 mil width, with a single-end impedance controlled at 90 ohms. Each PCB undergoes a 100% electrical test prior to shipment to ensure quality and reliability.

5. PCB Statistics:
This PCB includes a total of 28 components and 68 pads. It comprises 32 thru-hole pads, 21 top SMT pads, and 15 bottom SMT pads. There are 73 vias and 6 nets, enabling efficient electrical connections.
