(7)集成电路、贴片元件拆卸工具对应用较多表面安装的贴片组件及集成电路,应采用热风枪拆焊台专用工具,才能方便地取下。热风枪的主要部件是电热丝和气泵,配有温度调节和气流调节旋钮,如图2所示。(8)测电笔测电笔又称电笔,用来检测交流电的低压线路和电气设备是否带电,检测电压范围为60～500V。它有钢笔式和螺钉旋具式两种。2.常用检修仪器(1)万用表万用表是一种能测量多路电量参数且多量程的便携式仪表。常用万用表有模拟式(指针式)和数字式两种。
(7) Integrated circuit and chip component removal tools For more surface-mounted chip components and integrated circuits, hot-air gun desoldering station special tools should be used for easy removal. The main components of heat guns are electric wire and air pump, with temperature adjustment and airflow adjustment knob, as shown in Figure 2. (8) Measuring pencil Measuring pencil, also known as electric pencil, is used to detect whether the low-voltage AC line and the electrical equipment are charged. The detection voltage range is 60 ~ 500V. It has a pen-type and screw-type two. 2. Commonly used instruments (1) multimeter multimeter is a measure of multi-channel power parameters and multi-range portable meter. Commonly used multimeter analog (pointer) and digital two.
