Details:
Name: FR4 PCB
Composition: It is composed of glass fiber material and high heat-resistant composite material, and does not contain harmful asbestos components.
Features: It has high mechanical properties and dielectric properties, good heat resistance and moisture resistance, and good processability. Stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance exceeds the standard, suitable for products that require high-performance electronic insulation.
Process: The main steps are heating, pressurization, solidification, cooling, demoulding, etc.
Comparison of aluminum PCB and FR-4 PCB
✿ Plate performance comparison
FR-4 glass fiber board has high heat resistance, but poor heat dissipation performance; aluminum-based pcb circuit board has high heat dissipation; the performance of the two is different, the leading role is also different, and the application field is also very different.
✿ Manufacturing process comparison
The circuit layer of the aluminum-based pcb circuit board has only one layer, while the glass fiber board can have single-sided, double-sided, and multi-layer circuits, and the circuit is connected through the guide hole. The complexity of the two crafts is different, and the craft production process is also very different.
Application fields: computers, avionics products, LED displays, large-screen displays, electronic road signs, optical instruments, etc.
