【Abstract】 Effects of point cathode anodic bonding are theoretically investigated by using electrical circuit analog. The bonding current, incubation period and intimate contact area are calculated. The results show that the current decays rapidly at early stage during anodic bonding and then decreases slowly; the incubation period falls off exponentially as the bonding temperature is raised; the intimate contact area spreads nonlinearly with time.更多还原
