FR4 Electric Motor Carbon Ink PCB

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.

  • Product Details

Carbon ink can be used for keyboard contacts, LCD contacts and jumpers.  The printing is performed with conductive carbon ink.

·  Carbon elements must resist soldering or HAL.

· Insulations or Carbon widths may not reduce below 75 % of the nominal value.

· Sometimes a peel able mask is necessary to protect against used fluxes.
