What’s the LED PCB board?

The PCB board is the most important part of the LED display. If the PCB board is missing, the use effect of the LED display will be affected, so everyone must pay attention to the importance of the PCB board. In addition, the PCB board is used as the LED display An important part of it is of great importance.

The PCB board is an important component of the LED display. The quality of the LED display PCB board determines the display effect and life of the LED display. The LED display uses FR-4 fiberglass circuit board, FR-4 fiberglass Circuit boards are traditional electronic product circuit boards. Due to their good insulation, corrosion resistance, compression resistance, and multi-layer printing, they are widely used.

In fact, the raw materials of PCB are seen everywhere in our daily life, that is, glass fiber and resin. The combination of glass fiber and resin and hardening becomes a heat-insulating, insulating, and not easy to bend board. This is the PCB substrate. Of course, a PCB substrate made of glass fiber and resin alone cannot transmit signals, so on the PCB substrate, the manufacturer will cover a layer of copper on the surface, so the PCB substrate can also be called a copper-clad substrate. Because of the black PCB The difficulty of recognizing the circuit traces will increase the difficulty of repair and debugging in the R&D and after-sales stages.Generally, if there is no brand with profound RD (R&D) designers and a strong maintenance team, black PCBs will not be easily used.

It can be said that the use of black PCB is a performance of a brand's confidence in the RD design and post-maintenance team. From the side, it is also a manifestation of the manufacturer's confidence in its own strength. Based on the above reasons, major manufacturers are choosing PCB design for their products. When it is time, it will be carefully considered. Therefore, it is formed that most of the products with large shipments in the market that year used red PCB, green PCB or blue PCB version, and black PCB can only be seen on mid-to-high-end or top-level flagship products. , So customers should no longer think that black PCB is better than green PCB.

In the production of general indoor led display screens and outdoor led display screens, two-layer boards or up to four-layer boards are used, while in the small-pitch led display screens, four or more layers of computer circuits are used, and the more layers there are , The more complex the process, the more expensive the price. In the transparent LED display, Jucaiyuan Optoelectronics now uses a four-layer board. In order to save costs, the company's technical department is also constantly developing and trying to use two-layer circuit boards to make .
