PCB Solder Mask

Protect PCB with correct Solder Mask

Solder mask is an additional layer added to the PCB to protect the surface copper from oxidizing and prevent for any unwanted solder bridges between solder pads. At CCI Canadian Circuits we have the capability to use a variety of colors ranging from regular green to purple, white, yellow, black and many more for masking based on your preference.


We use Liquid Photo Imageable Mask (LPI) technique to apply Solder mask. Our solder mask capabilities have a minimum of 3.0 mils for green solder mask for a board with 1oz copper weight. For black solder mask our minimum solder mask is 4.0 mils. For details on Solder mask minimum dam capabilities for your custom PCB, download our Capabilities sheet below or Contact us.
