PCB color of PCB proofing determines the quality of PCB

PCB color of PCB proofing determines the quality of PCB


PCB proofing production PCB equipment judges the quality of PCB from PCB color. PCB purchasers always have doubts about the color of PCB, and do not know what color PCB is of high quality. Today we will explain how the color of PCB affects its performance.

First, as a printed circuit board, the pcb proofing PCB mainly provides the interconnection between electronIC components. Color is not directly related to performance, and different pigments will not affect electrICal properties. The performance of PCB is determined by the materials used (high Q value), wiring design and several layers of boards. However, in the process of PCB washing, black is the most likely to cause color difference. If there is a slight deviation between the raw materials used in the Pcb factory and the manufacturing process, the color difference will cause an increase in the defective rate of PCB. This directly leads to increased production costs.

In fact, the raw materials of pcb proofing PCB are ubiquitous in our daily life, that is, glass fiber and resin. Glass fiber and resin are combined and hardened to become a kind of heat insulation, insulating, and not easy to bend plate, which is PCB substrate. Of course, the PCB substrate made of glass fiber and resin alone cannot transmit signals. Therefore, the manufacturer will cover the surface of the PCB substrate with a layer of copper, so the PCB substrate can also be calLED a copper clad substrate.

Because the circuit routing of pcb proofing black PCB is difficult to identify, it will increase the difficulty of maintenance and debugging in the R&D and after-sales stages. Generally, black PCB will not be used easily without the brand of skilled RD (R&D) designers and powerful maintenance teams. It can be said that the use of black PCB is a sign that a brand has confidence in RD design and post maintenance teams. From the side, it is also a reflection of the manufacturers' confidence in their own strength.

Based on the above reasons, all major manufacturers will carefully consider when selecting PCB design for their products. As a result, most of the products with large MARKet shipments in that year used red PCB, green PCB or blue PCB versions, and only the high-end or top flagship products could see black PCB, so customers should not think that black PCB is better than green PCB.
