The glossy solder mask and matte solder mask for circuit boards are two different soldering techniques, and they have some differences in appearance and performance, catering to different application requirements. Here is a comparison between them:
Glossy Solder Mask: Glossy solder mask typically has a very smooth, shiny appearance that reflects light, giving the circuit board a very sleek and high-end look. This appearance is suitable for high-end electronic products such as consumer electronics and smartphones.
Matte Solder Mask: Matte solder mask, on the other hand, has a relatively rough, non-reflective appearance. It looks more subdued and is suitable for industrial and military applications or electronic devices where appearance is not as critical.
Glossy Solder Mask: The surface is smooth, suitable for applications that require a polished surface, but it can be prone to surface scratches.
Matte Solder Mask: The surface is relatively rough and less prone to scratches, making it suitable for some industrial environments.
Glossy Solder Mask: It typically requires more processes and special materials, making it more expensive.
Matte Solder Mask: It is generally more cost-effective as it does not require as many special treatments and materials.
Resistance to Contamination:
Glossy Solder Mask: Due to its smooth surface, it may be more susceptible to dust, fingerprints, and other contaminants.
Matte Solder Mask: Thanks to its rougher surface, it is better at resisting contamination and is suitable for applications in harsh environments.
Glossy Solder Mask: It usually has good high-temperature resistance, making it suitable for applications in high-temperature environments.
Matte Solder Mask: It also typically exhibits good high-temperature resistance, although it may be slightly less than bright solder mask.
In summary, the choice between Glossy solder mask and matte solder mask depends on the specific application requirements and budget for the circuit board. If appearance is crucial and there is a sufficient budget, glossy solder mask may be a better choice. If cost is a significant factor or if the circuit board will be used in industrial, military, or similar environments, matte solder mask may be more suitable.
Common PCB matte soldermask methods include matte black, matte green, and matte blue.
