台式激光剥线机可避免对关键电子设备造成损害

By: Shana Leonard

采用CO2激光技术的台式剥线机适用于包含关键电子设备的应用。
Ideal Industries Inc. 公司(美国伊利诺伊州,Sycamore; www.idealindustries.com)称,机械、热学或化学剥线工艺可造成意外切口、刮擦或触及导体,从而影响关键电子设备的完整性。鉴于上述问题,许多制造商开始采用激光剥线技术;但大多数激光剥线机体积庞大且造价高昂。Ideal Industries推出了据称是世界上第一台采用CO2激光技术完成360切割的台式剥线机,该激光剥线机具有成本较低且结构紧凑的特点。

“在医疗行业中,保证电子设备的质量以及剥离的电线信号的完整性是至关重要的,”Ideal精密导线加工应用工程师Peter Crichton强调说。“如果在手术过程中有一件设备置于体内,那么最不希望的就是由于剥线水平较差而造成电子设备出现故障。”

由剥线造成电子设备故障的主要原因是导体受到损伤。Crichton解释说:关键应用条件下的大部分导体均采用标准导体,它是由众多小型线料组合而成的。“剥线的关键之一在于如果切断其中的一股线,则将会丧失需要的电特性,且随着温度的升高和信号的整合,它还会带来其它影响,”他补充说。

而激光剥线技术采用的是光波。CO2激光的反射特性使其能切断聚合和聚烯烃材料,而不会切断金属。激光技术遇到导体则会弹开,不会影响到导体。

此技术已问世一段时间。Crichton指出,但WireMaster 台式产品是第一次将激光技术用于极小的装置——14.5 寸宽 12 英寸高 24 英寸深——完成360切割,且价格更低廉。它在去除包覆时还有纵向直切或螺旋切割两种方案可供选择。台式系统可以通过无接触工艺将仅0.001英寸的电线上的绝缘层迅速汽化。

由于该产品具有精密加工的性能,因此适用于各种医疗产品(包括电子手术仪器)。“医疗行业采用的电线直径极小,”Crichton说道。“电线直径越小,则剥线越困难,因为它无法达到机械剥线机所需的柱向强度,采用机械剥线机非常困难。”采用激光即可轻易解决上述诸多问题。
