PCB News - PCB color of PCB proofing to judge the quality of PCB board

The PCB proofing production circuit board equipment judges the quality of the PCB board from the PCB color. PCB buyers always have doubts about the color of PCB, and do not know what color PCB board is of high quality. Today, I will explain what effect the color of the PCB has on its performance.

First of all, PCB proofing PCB is used as a printed circuit board, which mainly provides interconnection between electronic components. There is no direct relationship between color and performance, and the difference in pigments does not affect the electrical properties. The performance of the PCB board is determined by factors such as the material used (high Q value), wiring design and several layers of board. However, in the process of washing the PCB, black is the most likely to cause color difference. If the raw materials and manufacturing processes used by the PCB factory are slightly different, the PCB defect rate will increase due to the color difference. This directly leads to an increase in production costs.

In fact, the raw materials for PCB proofing PCB are seen everywhere in our daily life, that is, glass fiber and resin. The glass fiber and resin are combined and hardened to become a heat-insulating, insulating, and not easy to bend board, which is the PCB substrate. Of course, PCB substrates made of glass fiber and resin alone cannot conduct signals. Therefore, 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.

As the circuit traces of the black PCB for PCB proofing are difficult to identify, it will increase the difficulty of repair and debugging in the R&D and after-sales phases. Generally, if there is no brand with strong RD (R&D) designers and a powerful maintenance team, it will not be easy to use. Black PCB. 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 choosing PCB board designs for their products. Therefore, most of the products with large shipments in the market that year used red PCB, green PCB or blue PCB version. Black PCB can only be seen on mid-to-high-end or top-level flagship products, so customers should not think of black anymore. PCB is better than green PCB.
PCB proofing manufacturer (Shenzhen Jiali Chuang) has focused on PCB proofing R&D and PCB manufacturing for 10 years. The delivery time is short, the service is good, and the quality is excellent. How about it? After Shenzhen Jiali Chuang took everyone to study together. Do you have a certain understanding of the PCB color of PCB proofing to judge the quality of PCB boards! Every bit of learning converges into a sea!
