Black PCB, different vision, different high-end



Subtle influence is a terrible process. It will make a lot of thoughts ingrained in your brain, even if this thought is just an illusion. Just like the color view in the PCB industry, everyone agrees that a black PCB must be a high-end, high-performance, and high-quality printed circuit board.


With the growing market for printed circuit boards in China and more and more PCB manufacturers in China, everyone is doing everything possible to promote their products. Among them are companies that use color strategies. They often consciously or unconsciously promote the color of the PCB, using black-themed advertisements such as high-quality black PCBs, black high-end PCBs, etc. to promote their company's products.


Black PCB, different vision, different high-end


In the electronics manufacturing industry, PCBs mainly come in several colors, such as yellow, blue, red, black, etc., which have evolved different levels of PCB quality. Often when propagating, the manufacturer will tell you the quality of our products with colors. But, in fact, is the quality of a PCB really tied to its color? Is it really determined by its color?


The raw material of PCB is actually glass fiber and resin that we usually see everywhere. The PCB substrate is a heat-insulating, insulating and non-flexible substrate formed by a series of processing such as bonding and hardening of glass fiber and resin. The PCB substrate is insulated, and we naturally cannot use the PCB substrate to conduct signals, so a layer of copper is covered on the surface of the substrate to form a copper-clad substrate, which is the so-called PCB substrate.


The black PCB first appeared in 2007. At that time, because the public version of the graphics card used a black PCB in its design, this also led downstream manufacturers to follow their knowledge and apply their knowledge. In the beginning, the black PCB was indeed only used in a few high-end graphics cards from some manufacturers, which indirectly proved that the black PCB is a high-end graphics card. The view at the time was valid, because other ordinary designs would not use black PCBs at all. Everyone believes this imperceptibly. Only when manufacturers use the imperceptible thinking of customers, black PCBs are also used in low-end products. , At this time, the black PCB and the high-end graphics card are not equivalent.


What is special about the black PCB?


In fact, in a printed circuit board, the color of the PCB is not directly related to its performance, because the difference in color does not affect the performance of the circuit board. The printed circuit board is mainly a carrier for the interconnection between electronic components. The performance of the PCB is felt by factors such as the materials used, the wiring, and the layer of the PCB. In the process of washing the board, black is relatively the worst color, because it is the easiest to cause chromatic aberration, which in turn will lead to more defective PCB boards, and ultimately increase the cost of production. Furthermore, the lines on the black PCB are difficult to identify, which means that only experienced R&D or designers can repair this layout, so under normal circumstances, manufacturers will not easily use black PCBs. In other words, when a company has enough confidence in its products, it is possible to use black PCBs to show its strength.


Black PCB has many inconvenient design factors, which also makes major PCBA processing manufacturers carefully consider when selecting PCB substrates. Therefore, red PCB, blue PCB and other colors occupy most of the PCB industry market, and only in Only high-end products are fortunate enough to see black PCBs, which indirectly proves that black PCBs are high-quality PCBs, and allows everyone to directly imply the definition of black PCBs.


However, many unsophisticated manufacturers use the customer's mentality to use black PCBs in low and mid-end products to pretend to be high-quality and high-performance PCBs. So we can't believe that black is high-end rumors. Of course, the black PCB also has some unique advantages, such as higher visibility of the text marking the welded parts and good visual effects.


Finally, it is emphasized that wanting to cover up the company's products with black is a self-defeating performance. If such a company blindly cut corners, it will die in the vast PCB arena.
