Recurrently available PCB circuit boards are green, yellow, or even brown, with green readily available. PCB boards hold a great deal of importance in modern electrical and electronic devices. Figure 1 shows a PCB board. Contrary to the PCB boards available in the market, the PCB board shown in figure 1 is blue. It gets one wondering the difference it makes to the PCB board functionality.
It must be admitted that as far as no visible difference appears in the green or blue circuit boards functionality, shortly, blue Circuit boards have become increasingly popular amongst designers and engineers owing to their attractive color. The user finds the blue circuit boards more eye-catching and appealing than the conventional dull green-colored boards. More details about these blue PCBsare elaborated in the further sections of the article.
Blue Circuit Board
It takes a great deal of time and energy to find a market that sells blue circuit boards as these are not readily available in the market. The blue color on the blue circuit board shown in figure 2 is not because of any paint, marked, dye, or silkscreen. In fact, the substrate itself is blue-colored.
Usually, single-sided blue PCBs are available to the designers. One side is for the components to be drilled, and the other is a plain solid blue board.
Blue Circuit Boards vs. Conventional Boards
As mentioned earlier, the functionality of the blue PCBs is similar to that of conventional boards. However, bleu are more appealing. Figure 3 shows a complex blue circuit board with components etched to its surface.
Figure 4 shows a simple blue PCB with basic components soldered to its surface.
Despite being highly in demand, the blue PCBs are not readily available to their users as other contemporary boards. Due to this lack of availability, they are expensive as compared with other boards. However, increasing these boards’ manufacture would make the blue PCBs more economical and readily available to its users. Most of the devices and commonly used sensors are preferred to be made on blue circuit boards. Blue PCBs provide easiness to its users to drill the components over the PCB boards.
