Which Colour PCB Is Best?

Red looks aggressive, eye-catching, and inviting, yet green is still considered the best. Blue: The Arduino blue hues and the soldering mask PCB color blue are comparable. Compared to printed circuit boards that are red and green, there is less contrast among planes, traces, & space.

Using the blackboard as an example, production process issues and raw material ratios will likely result in the blackboard’s noticeable color variations and high PCB rate of defects. In addition, it is challenging to locate the traces on the black circuit board, making maintenance and troubleshooting more challenging.

Positive Aspects of Green PCB

1. The yellow light chamber is required for many board-making and laminating procedures, as this is where the green PCB appears the best;

2. Because optical positioning and calibration are necessary for the processes of tinning patching, along with AOI calibration in the SMT patch process, green makes the bottom plate easier for the instrument to identify;

3. Certain inspections depend on worker observation; however, in most cases, this labor has been replaced by flying probe testers; this requires employees to maintain a prolonged gaze at the board in bright light, as green is an ocular pleasant color;

4. Circuit boards produced using green printing are comparatively eco-friendly, and recycling waste boards at high temperatures won’t produce harmful gases. Due to their cobalt and carbon doping, other colors like blue and black have poor electrical conductivity and can cause short circuits.

Which color is the PCB?

This is, of course, the first thought that pops into your head when you notice the number of color options available on PCBs. Despite our understanding of PCB colors, the pigmentation we observe on the PCB differs from the original board’s true hue. It’s a coating put on the FR-4 PCB substrate. The shade of color of the soldering iron mask used to cover the exposed copper wires determines the color of each board.

Choosing a color for the solder mask or oil that creates a pleasing visual contrast with the swathing wires made of copper can help them stand out. Because of their contrast, applying the color makes it easier for the designer & repair specialist to locate the copper wires. The colorful coating prevents short circuits in the copper wires.

How Do I Pick the Appropriate PCB Colors?

Let’s get right to the point: choosing the pcbasic pcba manufacturer!

• Examine alternative PCB product combinations

One of the colors that is simple to get for the soldering iron mask is green. This coat is often the thinnest, with a layer thickness of just 0.1 mm. Additionally, green is ideal for PCBs since it works well with the most significant number of PCB components, making repairs and board assembly easier.

• Consider both glossy and matte surfaces.

Choosing between a glossy and matte finish is entirely up to the designer. Both functions flawlessly; the matte coating has a porosity finish & gives them a darker appearance, while the shiny finish makes them more reflecting and provides the impression of having a hard shell.

• Take into account the batch and price.

Green is always the best option when choosing a solder mask color. Among all the colors, it is the most reasonably priced and easily accessible in large amounts. A manufacturer can also provide competitive pricing.


In conclusion, your unique requirements and tastes significantly influence the PCB color selection process. The truth is that PCB color has little bearing on functionality or performance, even though some might argue for the visual appeal of a particular shade or the practical use of high-contrast colors.
