  • What is solder mask?

    Solder mask is the greenish laquer-like film covering most of the copper area except the pads.

  • Do I really need solder mask?

    It depends – for hobbyist through hole PCBs, solder mask is more for aesthetics than functionality. For SMT boards, we highly recommend solder mask to ensure neat soldering. Solder mask was created mainly to facilitate wave soldering used in mass assembly. It also prevents solder from bridging between conductors, preventing short circuits.

  • What solder mask do you use for PCB production?

    We use green Liquid Photo Imageable (LPI) solder mask.

  • Does it cost more to use solder mask?

    No, the solder mask is a standard option for our prototype and production PCBs.

  • What different solder mask colours are available for my PCBs?

    Apart from green, we can also supply PCBs with white, black, blue or red solder mask. In some cases, it does not cost extra if you opt for different colour.
