CEM-1 Notebook Keyboard Carbon Oil PCB

CEM-1 Notebook Keyboard Carbon Oil PCB
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.
