Why PCB colorhas nothing to do with the quality of PCB boards?

Many newcomers to theindustry have doubts about the color of the PCB board, do not know what colorPCB board is of high quality. In fact, the PCB mainly provides theinterconnection between components, its color and performance, quality is notdirectly related to the color of the difference does not have an impact onelectrical properties. Why PCB color has nothing to do with the quality of PCBboards?

PCB raw materials areeverywhere we see in our daily lives, that is, glass fiber and resin. Glassfiber and resin combined, hardened, into a thermal insulation, insulation, andnot easy to bend the board, which is the PCB substrate. Of course, thecombination of glass fiber and resin alone from the PCB substrate is not ableto conduct signals, so the PCB substrate, the manufacturer will be covered witha layer of copper on the surface.

There is a situation where itis easy to make the mistake that the PCB color is related to the quality of thePCB board: individual PCB design using black, in the process of washing thePCB, it is easy to cause color differences; if the PCB factory uses rawmaterials and production process is slightly deviated, it will cause the PCBbad rate because of color differences, directly leading to increased productioncosts. As the black PCB circuit alignment is difficult to identify, it willincrease the maintenance and debugging difficulties in the R & D andafter-sales stages, there is generally no strength of the RD (R & D)designers and strong maintenance team of the brand, it is not easy to use theblack PCB. For these reasons, the major manufacturers in the selection of PCBdesign for the product, most of the red PCB, green PCB or blue PCB board, theblack PCB is rarely seen.

In short, the performance ofthe PCB board is good or bad is determined by the materials used (high Qvalue), wiring design and several layers of the board and other factors; PCBcolor has nothing to do with the quality of the PCB board.
