Products description:

Carbon ink PCB: Carbon ink is typically used to create a protective contact surface for switches.  It's typically much more cost effective than the typical alternative, which is hard electroplated gold. But the carbon inks must have good viscosity stability for warmer climates and require good printing properties to give even coverage over the copper pads.
