摘要: 为探究聚二甲基硅氧烷(PDMS)基体在等离子法下以不同工艺参数处理及处理后在不同键合时间,键合加载压力下的PDMS-PDMS键合效果,设计进行了3因素4水平正交试验及对比试验。试验结果表明:因素影响从主到次的顺序为空气流量、改性时间、射频功率,得到快速不可逆键合(键合5 min)工艺参数:400 W,2.5 L/min,2 min;中、高射频功率(300 W以上)键合10 h键合效果达到实验要求,低射频功率(200 W以下)键合超过24 h仍未达到试验要求;当键合加载压力超过0.4 MPa时,键合效果显著提升。Abstract: To explore the bonding effect of the polydimethylsiloxane(PDMS)substrate handled with different bonding time and bonding pressure after different process parameters of the plasma treatment. The three factor-four level-orthogonal tests and contrast tests was designed. The experimental results indicate that the sequence of the factors which organized by their influence is of:air flow rate > treatment time > radio frequency (RF)power. The parameters to get rapid irreversible bonding (Bonding 5 min) is:400 W, 2.5 L/min, 2 min. Under the middle or high RF power (300 W or higher), the bonding effects can meet the requirement with 10 h bonding. Under the low RF power (200 W or lower), the bonding effect can not meet the requirement after 24 hours. The bonding effect is significantly improved when the bonding pressure is more than 0.4 MPa.
