Basic information of Pcb board:

The performance of the ceiling display Pcb Pcba depends on the material, layout and number of layers of the board. However, in the process of manufacturing circuit boards, black is most likely to cause chromatic aberration. If the raw materials and manufacturing process used by the circuit board factory are slightly different, it will cause color difference and increase the utilization rate of the PCB circuit board. This will increase production costs.

Raw material ceiling display rack Pcb Pcba is very common in our life, it is composed of glass fiber and resin. The combination of the two forms a heat-insulating, non-flexible board after hardening. This is the PCB substrate. Generally, because the light combined by glass fiber and resin cannot synthesize a PCB substrate, we will cover its surface with a layer of copper. Therefore, for the following reasons, we also refer to the PCB substrate as a copper circuit board circuit. Black PCB wires are difficult to identify. Increasing the difficulty of development and customer service during the maintenance and commissioning phase. Without a general mastery of RD (R & D) design and a strong brand maintenance team, black PCBs are not easy. It can be said that the use of black PCB is the brand's RD design and maintenance team's confidence in performance. From the side, it is also a manifestation of the manufacturer's self-confidence.
