The only solder mask process we use is Liquid Photo-Imageable (LPI). Standard colour and finish is satin green.
Other standard colours in stock are: Black, Blue, Red, White & Yellow. A surcharge applies for any of these colours.
We DO NOT mix standard inks to make different colours!
We do not stock LED White soldermask which is used specifically for LED backplanes to provide a perfectly white finish.
Standard white soldermask is not opaque and will show through the salmon pink colour of the tracks and pads beneath it.
