SOLDER MASKS

Solder Mask Colors

IPC has established a testing standard for solder masks which is used as an industry guideline for material manufactures, OEM’s and PCB manufactures. IPC SM-840D classifies solder mask, Class T and Class H which are summarized below;

T – Telecommunication: includes computers, telecommunication equipment, sophisticated business machines, instruments, and certain non-critical military applications. Solder mask on boards in this class is suitable for high performance commercial and industrial products in which extended performance life is required, but for which interrupted service is not life-threatening.

H – High Reliability/Military: includes that equipment where continued performance is critical, equipment down-time cannot be tolerated and/or the equipment is a life support item. Solder mask on boards of this class is suitable for applications where high levels of assurance are required and uninterrupted service is essential.

What Are The PCB Solder Mask Color Options?

Solder Mask Colors 1

 

Green Solder Mask 

Telecommunications PCB

Green Solder Mask

The green solder mask is always a popular PCB solder mask option because it allows everything to be seen clearly. Green solder mask has good contrast between the areas under the solder mask with and without copper. You can easily see the traces with your eyes, whereas for black solder mask – you have no idea.

 

White Solder Mask

LED PCB

White Solder Mask

White printed circuit board solder mask applications are becoming slightly more popular because the white color can make a PCB visual look very pretty in a clean environment. However, the white solder mask hides traces very well. Naked eye inspection can become nearly impossible in some situations, especially if you’re in a room with only direct overhead light.

The ”white solder mask” looks different from different solder mask ink suppliers. Some turns to brighter, some turns to “milk color”. Make sure you and your PCB manufacture have the same understanding of what exactly “white solder mask” you want. Venture engineering team is more than happy to provide you with different “white solder mask” PCB samples for you to compare.

 

Black Solder Mask

Industrial PCB 5

Black solder mask

Black solder masks brings slightly less of a visibility concern compared to white options. In some applications, black PCB solder mask are not recommended because of the increase in heat, which may discolor silkscreen and make the board more difficult to clean.

 

Red Solder Mask

HDI PCB

Red Solder Mask

Red boards are becoming more and more popular options because they provide good visibility and contrast in planes, traces and even your empty space. It’s less contrast than green boards, but still it will give a PCB a feeling of freshness when compared to stale industry standards. Silkscreens stand out well against the red.

 

Blue Solder Mask

Embedded Resistor PCB

Blue Solder Mask

Label-heavy boards should consider a blue solder mask because of the significant contrast it creates with silkscreen. Traces under blue solder mask can become much more difficult to see without proper lighting and magnification. It is a little more likely to show dirt compared to other colors.

 

Yellow Solder Mask, Orange Solder Mask , Grey Solder Mask and more

High TG PCB

Yellow Solder Mask

Solder Mask Colors 5

Purple Solder Mask

Many new colors are emerging, but they can be difficult to manage. Sometimes, varying production lot will show slight difference. Yellow and orange are pleasing colors, but their contrast is pool in both silkscreens and traces. Grey solder mask are often considered in LED PCBS/ aluminum PCBs projects as well.

Crystal Clear Color Solder Mask

 

Different colors will balance different requirements, such as cleanliness, visibility and style.  You can always try a sample with us before start mass production for new color.

Matte vs. Glossy Solder Mask

Today’s PCB solder mask options also bring new finish designs, which don’t have to do with any coating material. Two of the most common options are matte and gloss solder masks. Before trying any for your next PCB design, you are more than welcomed to contact our sales for free samples – you can use the sample as a reference.
