| Abstract |
For fuse element fabrication with glass-ceramic substrate, photoetching technic was applied. To control copper layer thickness on glass-ceramic substrate, continuous electroless plating rates were monitored using QCM method. Plating rates were 0.6∼l㎛/hr, which value increased with Rochelle Salts addition. At 0.1%HF, 2min etching condition, adhesion between glass-ceramic and copper layer was most favorable. Etching factor value was most favorable at 1.8kgf/min injection pressure and 2.5M/L of etchant concentration. Fuse element design of stepped layer was a little effective for arc duration and preventing fuse temperature from rising suddenly. |
