Rogers RO4830 PCB With Low Profile Copper 5mil and 9.4mil High Frequency Thermoset Circuit Boards
Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.
General Description
Rogers RO4830 high frequency PCBs are constructed from advanced thermoset laminates, providing a reliable and cost-efficient solution for demanding RF and microwave applications. Rogers RO4830 PCBs serve as a high-performance alternative to traditional PTFE-based materials and are exceptionally suited for millimeter-wave devices where budget and performance must be balanced. A key application is in 76-81 GHz automotive radar sensors, where the RO4830 material is commonly utilized as the cap layer in hybrid FR-4 multi-layer board designs.
The dielectric constant of RO4830 laminates is engineered for stability, measuring 3.2 at 77 GHz, which is slightly higher than that of standard PTFE-woven glass laminates. A critical feature of RO4830 PCBs is the use of low-profile reverse-treated copper foil, which enables outstanding insertion loss performance of only 2.2 dB per inch at 77 GHz. The material's construction incorporates a flat woven e-glass reinforcement and a filler with a highly uniform, fine particle size, granting it superior laser drilling capabilities for precise fabrication. Furthermore, RO4830 PCBs include an advanced antioxidant package that delivers exceptional resistance to oxidation, outperforming other hydrocarbon-based circuit materials. These high-frequency boards comply with UL 94 V-0 flame retardant standards and are fully compatible with lead-free soldering processes.
Key Features:
- Dielectric constant of 3.24
2. Excellent insertion loss of 2.2 dB/in at 77 GHz
3. UL 94 V-0 flame retardant rating
4. Optimized filler, resin, and glass composite system
5. Reverse treated smooth low profile copper foil
Benefits:
- Remarkable resistance to oxidation
- Consistent within-sheet dielectric constant for reliable laser drilling performance
- Lower overall cost compared to PTFE laminate options, contributing to reduced PCB manufacturing expenses
- Ideal for automotive radar sensor PCB applications
