CEM-1 Notebook Keyboard Carbon Oil PCB
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.
The main technical parameters of Carbon oil PCB
