PCB board is the abbreviation of printed circuit board. Both LED aluminum substrate and FR-4 glass fiber circuit board belong to PCB. To say the difference, just compare LED aluminum substrate and FR-4 glass fiber circuit board. LED aluminum substrate is thermally conductive. The circuit is printed on the plane of the aluminum material with better performance, and then the electronic components are welded on it. The main purpose of using aluminum substrates is to have good heat dissipation. High-power LEDs have relatively large heat generation, so most aluminum substrates are used in the production of LED lighting fixtures. FR-4 fiberglass circuit board is a traditional circuit board for electronic products. It is widely used due to its good insulation, corrosion resistance, compression resistance, multi-layer printing and other characteristics.
1. High-efficiency production: PCB can realize the electrical connection between various components in the circuit, replace complex wiring, reduce the workload of wiring in the traditional way, and simplify the welding, assembly and debugging of electronic products;
2. Reliability and miniaturization: reduce the volume of electronic products, reduce product costs, and improve the reliability and product quality of electronic equipment;
3. Production standardization: It has good product unit interchangeability, and it can adopt standardized design, which is conducive to the mechanization of welding and the automation of production, and improves production efficiency;
4. Good maintenance and interchangeability: The components of the equipment have good mechanical properties and electrical properties, so that the electronic equipment can be produced in an assembly line, and the entire printed circuit board that has been assembled and debugged can be used as a spare part, which is convenient for the interaction of the whole machine products. Replacement and Repair.
