FR-4 MATERIAL VS. ROGERS MATERIAL
Here are the differences between FR-4 and Rogers’ material—based on certain factors.
| Factors | FR-4 Material | Rogers Material |
|---|---|---|
| Dissipation factor (DF) | 0.020 | 0.004 |
| Price | Affordable | Expensive |
| Thermal Management | This grade material doesn’t handle high temperature well. | The Rogers material manages high temperatures perfectly. |
| Performance | Decent | Remarkable |
| Dielectric Constant (DK) | 4.5 | 6.15 to 11 |
| Impedance Stability | Lower polarity and it doesn’t stabilize charges well. | Higher polarity and stabilizes charges effectively. |
| Applications | The FR-4 isn’t so ideal for space applications because it isn’t outgassing tolerant. | Rogers is a better option for space applications because it reduces outgassing effectively. |
