对于业余电子爱好者,手头没有专用工具拆卸IC是件麻烦事,尤其是遇有双面焊接的IC。这里介绍一种自制的烙铁头,配用20W内热式烙铁即可将IC拆下,制作简单,经本人十多年使用,效果很好。取1～2mm厚紫铜板裁出图1形状,将其夹在合钳上沿φ5mm钻头杆卷一圈如图2形状,并在上面钻φ3.5mm孔穿入M3螺丝带上帽作紧固用。再将图2中的B段用锉刀 For amateur electronics enthusiasts, having no special tools on hand to disassemble the IC is a nuisance, especially in the case of double-sided soldered ICs. Here to introduce a homemade tip, with a 20W heat soldering iron to the IC removed, making simple, by myself for more than 10 years, the effect is very good. Take 1 ~ 2mm thick copper plate cut out the shape of Figure 1, the clamp on the clamp along the φ5mm drill rod roll circle as shown in Figure 2 shape, and drill φ3.5mm hole drilled into the M3 screw cap use. Then in Figure 2 in the B section file
