Black Solder Mask
At Bittele Electronics we offer a large variety of colours for our solder masks. One of the most unique colours we offer is the Black Solder Mask. The colour black is known for being less reflective than other options, thus a PCB that uses black solder mask will not reflect light, and this is great for boards that are used as displays.
However, the black solder mask actually absorbs more heat than normal during reflow. Thereby adding an extra days turn time to our fabrication process when black solder mask is used. Although the silkscreen contrasts very well with a black solder mask the contrast between traces, empty spaces, and planes is almost non-existent. This makes the visual inspection of the boards more difficult than usual and requires extra care. Bittele Electronics offers Black LPI Solder Masks in both matte and gloss options.
