1-108 Layer Rigid Fr4 PCB Manufacturing Companies

♦ What's Fr4 PCB?

​​FR4 PCB​​ refers to a printed circuit board (PCB) made with ​​FR4 material​​, the most widely used substrate in electronics manufacturing.

♦ ​​​​Key Features of FR4 PCB:​

1. 1. ​​Material Composition​​

      • ​​FR4​​ stands for ​​Flame Retardant 4​​, indicating its fire-resistant properties.
      • Made of ​​fiberglass-reinforced epoxy laminate​​, providing strength and durability.

   2. ​​Electrical & Mechanical Properties​​

      • ​​Good Insulation​​ – High dielectric strength prevents electrical leakage.
      • ​​Thermal Resistance​​ – Can withstand temperatures up to ​​130–140°C​​ (higher for specialized variants).
      • ​​Mechanical Strength​​ – Rigid and sturdy, suitable for most PCB applications.

   3. ​​Common Applications​​

      • Consumer electronics (smartphones, laptops, TVs)
      • Industrial control systems
      • Automotive electronics
      • Medical devices
      • IoT and embedded systems

♦ ​​​​Advantages of FR4 PCB:​

✅ ​​Cost-effective​​ – Cheaper than high-frequency or ceramic PCBs.
✅ ​​Versatile​​ – Works for most standard electronic applications.
✅ ​​Durable​​ – Resists moisture, heat, and mechanical stress.
✅ ​​Easy to Manufacture​​ – Widely available and compatible with standard PCB fabrication processes.
