PCB Glossary

  • Solder Mask Color

    LPI Green is our default solder mask color. We have options on the MCL website for additional colors of blue and black. Please note that there is an added charge for these other colors, and they can add an extra day to your build time due to the additional processes needed for the non-standard colors.
