Black Solder Mask

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.
