技艺高超的“车辆医生”

2017-08-30 09:37:23   中国青年网

电烙铁携带微小而圆润的焊锡熔珠,在主板上轻轻划过,焊锡自然均匀分布在芯片引脚上。每次参加技术比赛,“云岭首席技师”王超展示手工焊接集成电路主板芯片的绝技时,总会引来阵阵赞叹。

王超是昆明铁路局昆明车辆段检修车间攻关组的一名车辆电工,年仅35岁的他是职工中公认的“大拿”,曾被授予“云岭首席技师”、 “昆明铁路局首席技师”等荣誉称号。他工作起来格外细致,宛如一位外科医生在给主板“缝针”。

记者采访当天,王超正在焊接的DSP主程序芯片只有4平方厘米大,却密集分布着216只引脚,每只引脚仅有头发丝粗细,间距不到0.5毫米。要确保每只引脚牢固焊接在主板上,既不虚焊,又不能相互粘连,难度非常大。这枚芯片位于逆变器主控板的核心位置,是负责给列车车厢空调、电炉、照明灯等设备供电的关键部件。以往逆变器主控板出了问题,因检修能力有限,昆明车辆段只能将主控板送回生产厂家修理,既占用了大量的时间,影响车辆正常使用,还需要付出高额的检修费用。

为了找到有效的检修方法,王超购买了电子元件焊接工艺的相关书籍,上网搜索技术论文,并利用业余时间走遍了大大小小的电子产品维修店。他边总结边试验,终于研究出一套成功可行的焊接方法。“焊接时要讲究‘似连非连’的感觉,才能平稳地带着锡焊珠子往前走。”王超说。

王超的工作主要是对旅客列车车辆电源系统进行检修。作为一名“车辆医生”,他一直在攻关。自2002年7 月参加工作以来,他已经先后成功攻克了逆变器、充电机集成板卡检修技术难关,解决了该段触摸屏修复、电磁灶试验检修等50多个难题,每年为昆明车辆段节约上百万元材料费。他独创的“统型逆变器试验装置”,大幅提高了车辆检修效率;他设计的“网络通信试验柜”具有网络通信试验和故障诊断功能,解决了该段多年来不能地面试验车下电源通信功能的问题,为单位节约设备采购成本近百万元。
