- Resistant to CAF, ensuring high reliability in PCBs
- Meets RoHS requirements
Factors to Consider for Isola 370HR PCB
When utilizing Isola 370HR PCB material, it is essential to consider the following factors:
1) Manufacturability
Factors such as multiple pressing performance, temperature performance, CAF/heat resistance, mechanical toughness, and fire rating play a crucial role in ensuring reliability.
2) Various Performances Matched with the Product
Ensure low loss, stable Dk/Df parameter, low dispersion, and good impedance control for optimal performance stability.
3) Timely Availability of 370HR Material
Communication with the manufacturer in advance is key to ensuring timely procurement of materials.
4) Cost Consideration
Consider the price sensitivity based on the application, whether consumer or industrial.
5) Compliance with Laws and Regulations
Adhere to environmental protection regulations such as RoHS and halogen-free requirements.
Selection Criteria for High-Speed PCBs
For high-speed digital circuits, the operation speed is a critical factor in PCB selection. Different circuit speeds require specific PCB characteristics:
- 10Gb/S digital circuit: Medium to low loss PCB
- 25Gb/s digital circuit: PCB with lower loss
- 50Gb/s or higher: Ultra-low loss PCB
