工作原理
等离子清洗机产生等离子体的装置是在密封容器 中设置两个电极形成电场，用真空泵实现一定的真空 度，随着气体愈来愈稀薄，分子间距及分子或离子的 自由运动距离也愈来愈长，受电场作用，它们发生碰 撞而形成等离子体，这时会发出辉光，故称为辉光放 电处理。 辉光放电时的气压大小对材料处理效果有很 大，另外影响与放电功率，气体成分及流动速度、材 料类型等因素也有关。 电浆在真空条件下,将产品表面暴露在放电的气体 中,使气体在产品表面反应. 当所使用为非聚合性气体( 如N2,O2,Ar….)时,将使产品表面有被蚀刻其它化学性质 之效果 .

在光电子领域中，管帽实现了两大基本功 能。首先，它们对传输和接收应用领域中的光 学元件提供了持久可靠的保护。其次，作为光 学接口，它们还确保了光学信号的顺利传输。 因此，安装在管帽中的窗口或透镜的光学性质 必须达到相当高的要求。

TO 管座
TO 管座为安装半导体、激光二极管或简单电路等电 子和光学元件提供了机械基础，同时通过引线为封装元件 提供电信号。探测器和激光器等光学元件特别容易受到环 境的破坏。尤其是湿度，可致使半导体元件迅速腐蚀，导 致整个器件出现故障。因此这些元件需要被提供可靠持久 的保护。

Can Welding
电阻焊接原理 电阻焊是用电极对被焊接物施加一定的压 力的同时通电、利用电极间的接触电阻产 生的焦耳热熔化金属而达到焊接的目的。 焊接电流的通电方式 一般从焊接物的形状去决定焊接电流的通 电方法、大致可分为三类。另外对于不同 的通电方法施加不同的压力、据此选择相 对应的焊接头。 焊接质量的评估 1.封帽过程中看不见电极与器件接触产生 电火花 2. 目视比较平滑没有毛刺 3. 测漏,leak test
