What is Red PCB ?

To comprehend the colors of PCB, we must be conscious that the coloring on a PCB is not the true color of the initial circuit. It’s a layer on the substance of the FR-4 PCB. The color observed on each board is due to the solder mask color, which shields the pure conductors on the panel.

The solder mask or copper oil color choice should be so high that it contrasts well with the top copper wires, and they can be identified readily. The colorful layer prevents the copper cables from short circuits. It also forms a protective layer against ordinary wear and scratches caused by extreme weather stress or any other potential cause for board deterioration.

A red PCB color code is normally used to distinguish the circuit from other boards. The main objective of adopting a red PCB color code is to recognize any specific component in a collective assembly.


The PCB color specifies the soldering oil or solder mask color. It comprises lacquer infused with colors known to preserve the exposed copper traces. The final color of the PCB is manufactured by mixing – epoxy, resembling the solder mask. Preventing short circuitry is one of the major uses of the solder mask.

What is Red PCB?

The hue of the red PCB solder mask is usually courageous and competent. There is quite a significant distinction between planes, voids, and traces.

Contrast is reduced, unlike the green PCB. Any amplification is used to check the traces of the board in the event of faults. It should be mentioned that the silkscreen is well-known for residual fluxes against the red backdrop. While red appears lovely, beautiful, and strong, green is still the finest.

Advantages of Red PCB:


Red PCBs enables you to connect all these aspects and use copper paths rather than wires so that comparatively tiny modules and wire saving are comfortable to control.

Ø Easy to repair:

If your Red PCB does not function reliably, the boards can be repaired very easily. That’s because the elements are easily checked and repaired, as all capacitances are labeled with a silkscreen on the panel. It not only makes the structure comfortable but also the consensus model.

Ø Time Saver:

The traditional method of creating circuit boards takes a lot of time. But the red PCB not only requires less effort to use the printed circuit board’s technique but is much more useful.

Ø Fixed components:

During the construction of the electronic components, all of the modules are connected to the board and properly fastened. This is completed by solder flux that does not allow migration to dislocate the parts.

Ø Lesser chances:

All connection is established by copper and metal conductivity rails. There is indeed less chance of losing connections which can outcome in the board being short-circuited.

Ø Electronic noise reduction:

The red PCBs are so created that electronic noise can be hardly detected. Any disturbance in the presence of energy or radioactivity is discharged. A properly designed PCB gives noise. This is because the elements are so arranged that the distance sizes are very close to zero, and thus the radioactivity and EM ripples are relatively low.

Ø Lower price:

While most PCBs are established on computerized systems, the template concept design can be saved and used repeatedly when needed. Therefore, you can save time and money on many lots of extremely similar red PCBs at once.

Other Colors of PCB’s:

Before seeing the red PCB now, we will know about the various color options available for the Circuit board. The usual color of PCB is the green overlay. However, the color of PCBs is altering with the emergence of significant innovation and technical progress. In the latest days, most assemblies have pushed the usage of different colors rather than green PCBs. The below are some reason behind choosing apart from green-colored PCBs:

  • Using various PCB colors offers a clear sign of the changes in iteration to inform users.
  • Brightness or reduction will be achieved by using colors apart from green. You have to realize that assembly material is important due to transmission, absorption, and light reflection.
  • Different colors assist in avoiding different sorts of faults in a combined assembly. The choice of color kinds in comparison also benefits from the identification of result meetings.

The colors utilized to make PCBs include yellow, red PCB, black, white, blue, etc. PCB colors are often referenced as color codes for PCBs. Some current PCB types have adopted specific colors. The PC boards, for illustration, are still made of green epoxy.

The colors of the solder masks don’t influence the functioning of the PCB. However, the proven approach will be varied if various PCB colors are used. Contrastingly, blue and red hues like yellow and black mimic green PCB density with a slightly lower resolution. It should be emphasized that solder masks are very committed with clear visibility.

Colors of the solder mask:

Different varieties of solder mask colors have been shown. When combined, chromium and carbon generate a dark solder mask. The existence of carbon is conducive to this sort of solder mask. Leading layers are produced via PCB traces but may be utilized as a shield to isolate signals from diverse external sounds.

The black solder mask is very pricey, produced from a cobalt combination. Like most Optoelectronic devices, you will find simple PCB color codes. The blue solder mask is usually seen in LCDs. It is utilized to prevent any interruption in the system.

A red PCB color code is normally used to distinguish the circuit from other panels. The main objective of adopting a red PCB color code is to recognize any specific component in a bunch assembly. Red solder mask is usually utilized in precise equipment such as oscilloscopes, analog resources, and voltmeter bench.

Green is regarded as the popular color for printed circuit boards from several sources. This is because the green color performance is superior to other PCB colors. Green produces better outcomes when connecting the element pitch. Green is typically believed to be the default color for printed circuit boards.

Types of Colors in PCB:

If you are ready to pick the printed boards, various criteria must be taken into account. One of them is to choose the PCB solder mask color. Although green is the most typical hue, there’s no additional price for other colors, such as yellow, red, black, and white, that are also possible. Because the PCB solder mask has a wide variety of colors accessible, the challenge is which color has to be picked. Does the choice of color other than green have any benefits or downsides?

The brief instructions below will help you choose a different color from the typical green hue of the solder mask:

Ø Blue PCB:

PCB in blue color mimics the very same Arduino blue for the solder mask. The distinction between vacant areas, surfaces, and traces are modest compared with yellow and white printed circuit boards. In the color of the blue solder mask, magnification is regarded as essential and required for inspection of production flaws.

However, the disparity between the solder mask and the silkscreen can be observed as pretty great, utilizing the blue color. So if you use a label board, hefty, then the correct option may be blue for you in this scenario.

Remember that blue appears to be a great option if you’d like to combine the solder mask color with your Arduino.

Ø White PCB:

If you believe that it is the most difficult to manage a black solder mask, you haven’t seen white yet. Results revealed that a white solder mask is not acceptable. The contrast between white PCB and black is even worst. Even turning it to illumination does not assist with the appearance of its traces while examined. The white PCB is very difficult to clean since suggestions are difficult to spot. However, with white solder masks, the silkscreen intensity is the same as in black, which means they function quite well. Because of other characteristics, the white solder mask is not recommended.

Ø Black circuit board

One of the most complex integrated circuits is the black circuit board. It is nearly hard to distinguish between empty areas, lines, and traces using the blackboards. You must thus tilt the board over a light beam to check it.

Though on the other side the electrodes are extremely clearly defined if they work with a unique silkscreen. It enables the identification of spots easier but also designated accurately.

Apple is renowned for adopting black PCBs for its iPhones and MacBook boards.

Ø Yellow PCB

The yellow circuits are excellent and why most manufacturers don’t choose their solder mask color is still an astonishment. Yellow provides a more detailed contrast among empty areas, trails, and planes. It’s indeed comparable to the green color mask with a simplistic approach to use.

Ø Purple circuit board:

The purple hue is not a conventional or typical color on a PCB. You may be asked to pay a surcharge for this color option based on your fabricator. The contrast is great with the purple PCB, and the general workability is increased.
