PCB Blog - Different vision of black fr4 pcb

Imperceptibly, it is a terrible process. It will make many thoughts deeply rooted in your mind, even if this thought is only an illusion. Like the color view in the fr4 pcb industry, everyone agrees that the black fr4 pcb must be a high-end, high-performance, high-quality printed circuit board. With the growing market of printed circuit boards in China, there are more and more fr4 pcb manufacturers in China, and everyone is trying every means to promote their products, including companies that use color strategy. They often publicize the color of fr4 pcb consciously or unconsciously and promote their company's products with high-quality black fr4 pcb, black high-end fr4 pcb, and other black-themed advertisements.

In the electronic manufacturing industry, fr4 pcb mainly has several colors, such as yellow, blue, red, black, etc., which also evolved different levels of fr4 pcb quality. In the process of publicity, the manufacturer will tell you the quality of our products by color. But, in fact, is the quality of fr4 pcb really related to its color? Is it really determined by its color? The raw material of fr4 pcb is actually glass fiber and resin that we can see everywhere. Fr4 pcb substrate is a kind of heat-insulating, insulating and inflexible substrate formed by glass fiber and resin after a series of processing, such as bonding and hardening. The fr4 pcb substrate is insulated. Naturally, we cannot use the fr4 pcb substrate to transmit signals. Therefore, a layer of copper will be coated on the surface of the substrate to form a copper-clad substrate, which is also known as the fr4 pcb substrate.

The black fr4 pcb first appeared in 2007. At that time, the public graphics card used the black fr4 pcb in its design, which also led downstream manufacturers to follow suit. At the beginning, the black fr4 pcb is really only used in a few high-end graphics cards in some manufacturers, which indirectly proves that the black fr4 pcb is a high-end graphics card. At that time, the view was valid, because other ordinary designs would not use black fr4 pcb at all, and we also believed this imperceptibly. Only then can manufacturers take advantage of the customer's imperceptible thinking and use black fr4 pcb in low-end products. At this time, black fr4 pcb and high-end graphics cards are not equivalent.

What is special about the black fr4 pcb?

In fact, in printed circuit boards, the color of fr4 pcb has no direct relationship with its performance, because the different color will not affect the performance of the circuit board. A printed circuit board is mainly a carrier of interconnection between electronic components. The performance of fr4 pcb is determined by the material used, wiring and board layer. In the process of plate washing, black is relatively the worst color, because it is most likely to cause color difference, which will lead to an increase in the number of fr4 pcb defective plates, and ultimately increase the production cost. In addition, the lines on the black fr4 pcb are difficult to identify. That is to say, only experienced R&D or design personnel can repair this layout, so the manufacturer will not easily use the black fr4 pcb. In other words, when an enterprise has enough information about its products, it is possible to use the black fr4 pcb to show its strength.

The black fr4 pcb has many inconvenient design factors, which also makes the major fr4 pcbA processing manufacturers carefully consider when selecting the fr4 pcb substrate. Therefore, the red fr4 pcb, blue fr4 pcb, and other colors occupy most of the market of the fr4 pcb industry, and only in high-end products can the black fr4 pcb be seen, which also indirectly proves that the black fr4 pcb is a high-quality fr4 pcb, It also allows you to directly and imperceptibly influence the definition of black fr4 pcb. However, many manufacturers without strength now use the mentality of customers to use black fr4 pcb in low-end and mid-end products to fake high-quality and high-performance fr4 pcb. So we can't believe that black is a high-end rumor. Of course, the black fr4 pcb also has some unique advantages, such as the high visibility of text marking weldments and good visual effect. Finally, I would like to emphasize that trying to cover up the shortcomings of the company's products with black is a sign of self-destruction. If such enterprises continue to cut corners, they will die in the vast fr4 pcb arena.
