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.

Carbon registration

 

Registration measuring will be performed using a selected reference mark in the Cu-pattern.

These targets are automatically integrated in our production panel frames.
