The choice of solder mask color on PCB printed board is related to its performance?
The PCB board mainly provides interconnection between electronic components. Color is not directly related to its performance. The difference in color will not affect the performance of electrical appliances. The performance of the circuit board is determined by factors such as the materials used, the layout and the number of layers of the board. However, in the process of making circuit boards, black is particularly prone to chromatic aberration. If the raw materials and manufacturing processes used by circuit board manufacturers are slightly deviated, the defect rate of PCB circuit boards will increase due to the chromatic aberration. This will increase production costs. The raw materials of circuit boards are very common in our lives. It is composed of a combination of fiberglass and resin, etc., hardened to form a kind of thermal insulation, insulation, and not easy to bend. This is the circuit board substrate. If the PCB substrate composed of glass fiber and resin alone cannot transmit signals, we will cover the surface with a layer of copper, so we also call the PCB substrate a copper-clad circuit board. Because the circuit traces of the black PCB board are difficult to recognize, it will increase the difficulty of maintenance and debugging in the R&D and after-sales phase. Generally, if there is no strong RD (R&D) designer and a strong maintenance team, the circuit board factory is not Will easily make a black PCB board. It can be said that the use of black PCB is 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 will carefully consider when selecting PCB board designs for their products. Therefore, most electronic products use red PCB boards, green PCB boards or blue PCB boards. The black PCB boards can only be seen in mid-to-high-end or top flagship products, so it is not to say that black PCB boards Better than the green PCB board, the color has no direct relationship with the performance of the PCB circuit board.
