Rigid PCB Materials
Choose the best material based on mechanical strength, weight, processability, electrical performance, and thermal management.
| Material | Core Composition | Thermal Conductivity | Electrical Insulation | Mechanical Strength | Weight | Processing Difficulty | Electrical Performance | Thermal Dissipation | Typical Applications |
| FR4 | Epoxy + Glass Fiber | ~0.3 W/m·K | High (>20 kV/mm) | High, prone to warpage | Light (1.9 g/cm³) | Easy, low cost | Low Dk, good for RF | Copper foil + thermal vias | Computers, phone motherboards |
| Aluminum PCB | Circuit + Dielectric + Al | ~200 W/m·K | Medium (≤2 kV) | High, low warpage | Medium (2.7 g/cm³) | Requires depth routing, +30% cost | Dk≈3, limited RF | Aluminum core | LED strips, auto power modules |
| Copper PCB | Circuit + Dielectric + Cu | ~380 W/m·K | Same as Al, thinner dielectric | Very high, heavy | Heavy (8.9 g/cm³) | Hard, 3–5× cost | Same as Al | Copper core, best thermal | Lasers, RF amps, military high-power modules |

Our Rigid PCB for Various Industrial Applications
Thanks to its four core strengths—dimensional stability, high load-bearing capacity, low cost, and high layer count—rigid PCB has become the “universal base” of the electronics industry, spanning everything from daily consumer goods to space applications. From phone mainboards to satellite power supplies, from household LEDs to 800 G switch backplanes—whenever you need “stable, dense, economical, and high-current,” rigid PCB at Zintilon is the first and best choice.
Rigid PCB FAQs
We accept T/T and PayPal payments.
We understand that clients may need to make some adjustments after receiving the sample. Minor modifications can be done free of charge. However, if the modifications are substantial, we will need to reassess the price and delivery time.
Project lead time and cost depend on its complexity. Zintilon will spare no effort to provide the most competitive prices and the fastest delivery time.
