Types of PCB Colors

Below are some of the various types of PCB colors.

Blue PCB

Often, blue PCBs are referred to as blue boards made of a copper-clad core, which is a similar layer of copper.

Ideally, blue PCBs are perfect for applications that require higher strength, like controlling heavy machinery, since they have a denser and thicker layer of copper. 

Also,  blue PCBs operate at a higher voltage, facilitating the flow of high current through them.

Furthermore, you can get blue PCBs with various coatings, such as a conformal coating or tin finish.

Such coatings offer different properties, therefore making them ideal for specific applications.

These are normally light blue; however, they’re available in various other colors. You can get them in different thickness levels ranging from 1/4” – 1/16”.

Green PCB

Green PCBs, often referred to as green boards, are ideal for low-power applications such as simple electronics.

Also, they’re easier to manufacture at a low cost since only one side of the PCB is coated with copper. 

Furthermore, such boards are rather slim ranging from about 0.062” – 0.031”.

Black PCB

Black PCBs are made with a higher percentage of copper, making them ideal for applications requiring high amounts of current, like electric heaters, distributing power within the electronic product. 

Also, black PCBs offer higher resistance and are, therefore, less efficient compared to standard PCB boards. 

However, black PCBs offer better voltage regulation, making them ideal for high-frequency applications, such as  SWPS, power supply rectifiers, and high-voltage applications.

You can use red PCBs for several reasons, such as to mount and secure components or make electrical connections. 

Red is a popular PCB color choice since it’s easily visible and distinguishable from other colors. 

If you choose a red PCB, it’s important to consider the number of layers and the board’s shape, thickness, and size.

What is Black PCB?



Black PCB is a special type of printed circuit board that is black. The black color is achieved by adding a black solder mask to the PCB.

The black solder mask is a thin layer of polymer that manufacturers apply to the PCB during manufacturing.

The black solder mask is what gives black PCBs their unique look. The black mask helps to hide imperfections in the PCB and makes the PCB look more professional.

In addition to the black color, the black circuit board has a glossy finish.

This glossy finish is achieved by adding a black solder resistor to the PCB. The black solder resist helps to protect the black solder mask from damage and also provides a nice finishing touch.

Black solder masks are becoming more popular for a variety of reasons. One reason is that the black circuit board tends to be less expensive than other colors of PCBs.

Another reason is that black PCBs are more durable and tend to last longer than other colors of PCBs. Finally, they tend to have a more professional appearance than other colors of PCBs.

Disadvantages of Black PCB

The main difference between black PCBs and other PCBs like blue, yellow, and red PCBs is the use of a different color solder resist paint. 

If both the design and manufacturing process for all PCBs are the same, then the color shouldn’t significantly impact the performance.

Like most things, black PCBs aren’t perfect and pose several disadvantages, such as the following.

  • Any slight scratches or stains are easily noticeable on black PCBs. During transporting and storage, any mishandling could make the product appear unappealing. Further, you’ll find that trying to get rid of stains on a black PCB could worsen things.
  • They offer a low surface resolution. With insufficient light sources, it’s difficult to tell apart the routes on the black PCB surface, making it difficult for DIY makers and factory visual inspection.
  • Black ink is a bit more toxic despite costing more than green ink, making wastewater management more difficult for PCB manufacturers.

Some Misconceptions About Black PCB

Process of applying solder mask colors on PCBs

This is how to apply solder mask colors on black PCBs.

STEP 1:  Clean the board

Cleaning and rust removal is necessary before applying resin to the board. Oxidation also gets removed during cleaning.

STEP 02:  Applying resin to the surface

When finishing the board cleaning,  Seal the exposed film with a transparent blank film, then insert a syringe or plunger into it.

STEP 03:  Spreading resin

Make a tiny transparent film and cover the resin positioned with it. And this ensures that the resin covers the entire board without leaving any gaps.

STEP 04: Squeegeeing resin

After the resin has been applied, use a squeegee to spread it evenly over the pcb board.

STEP 05:  Placing solder mask

Epoxy the film of the solder mask over the board after you coat it. And then align the film correctly after that.

STEP 06:    Curing the board

After placing the solder mask, cure the board with UV light. As this will harden the resin and make the black pcb board ready for use.

STEP 07:  Peeling of the film

The final step is to peel off the film of the black pcb board. And your black pcb is ready!

How To Choose PCB Color

Choosing the right color for your PCB depends on more than just your preference.

It’s important to consider a number of technical and design factors to ensure optimal functionality, performance, and visual appeal.

Product Aesthetics

Products that are vibrant and playful could use brightly colored PCBs, whereas sleek products with modern designs could benefit more from black or metallic colors. 

Market Preferences and Target Audience

The variety of segments prefer different colors. Simply conducting market research while also analyzing industry trends to get the preferred color of your target audience could go a long way in making your product successful. 

Brand Identity

Choosing a unique and distinctive color for your PCB could help your product stand out from other products and help create a memorable experience for your potential customers.

This is especially important for products in a competitive landscape.

You can consider the color choices currently being used in the market and try to deviate from the normal while still maintaining visual harmony.

That kind of strategic thinking could offer your product an edge while reinforcing its brand and market position.

Signal Integrity and Electromagnetic Interference

The color of the PCB you choose could affect the electromagnetic interference issues and signal integrity.

For better EMI shielding, it’s better to opt for darker colors (like blue or black) that reduce the threat of interference and, thus, signal degradation.

However, lighter-colored PCBs are more prone to EMI as a result of their absorption properties and lower reflection. 

Dissipation of Heat and Thermal Management

Many electrical device­s, especially high-power one­s, need good heat control and thermal management. 

PCBs that are dark-colored do a better job at soaking up heat, therefore helping keep the device cool. Light-colore­d PCBs, though, reflect heat, which could lead to overheating problems.

Visibility and Contrast of Component Markings

On a PCB, silk scre­en labels and reference designators are­ valuable for part identification.

These matter when you’re putting together and testing the PCB as well as fixing it later.

The right PCB color can make the labels easier to read. That, in turn, makes assembly and fixing quicke­r and more efficient.
