A Guide to the Operation of Solder Wires
一般而言，手工烙铁焊时烙铁头温度应该是焊料熔点温度再加上150℃，有铅锡线烙铁头温度一般可设定为330℃，无铅锡线烙铁头温度一般可设定为370℃。手工烙铁焊的正确顺序应该是烙铁头首先接触焊盘，将热量传递到焊盘从而使焊盘温度升高，然后再将焊锡丝放到焊盘上，此时焊盘的温度应该足以熔化焊料从而形成连接。因为熔融的焊锡具有向温度高方向流动的特性，先接触焊盘，它会很快流向烙铁头接触的部位，可保证焊点四周均匀布满焊锡。若供给的焊锡线直接接触烙铁头，焊锡丝很快熔化覆盖在焊接处，如工件其它部位未达到焊接温度，易形成虚焊点。特别要注意的是不能将焊锡线直接接触烙铁头，因为烙铁头温度很高，这样操作很容易造成飞溅，严重时可能烫伤工人。
撤离烙铁：焊锡已经充分润湿焊接部位，而焊剂尚未完全挥发，形成光亮焊点时，立即脱离（每个焊点焊接时间 2~3 S），若焊点表面无光泽而粗糙，说明撤离时间晚了。
Generally, in the manual iron soldering, the temperature of iron head should be the temperature of the melting point of solders plus 150℃. The temperature of the lead solder wires can generally be set as 330℃, and the temperature of non-free solder wirescan generally be set as 370℃. The right sequence of manual iron soldering should be the temperature of the first contact of the pad. The heat will be transmitted to the pad so that there will be a rise in the temperature of the pad. Then place the solder wires on thepad. Now, the temperature of the pad should be high enough to melt the solders and form bonding. Therefore, the melted solders have the properties of flowing towards the direction of higher temperatures to contact the pad first of all. It will soon flow to thepart of the iron head contact so as to ensure that the perimeters of the pad will be well distributed with solders. If the supplied solder wires directly contact the iron heads, the solder wires will be soon melted and cover at the welds. If other parts of work pieces fail to live up to the welding temperature, it is easy to form virtual soldering point. Special attention should be paid that the solder wires should directly contact the iron heads. Since the temperature of iron heads is very high, this will easily cause spatters, or may burn workers when the case is severe.
Take out irons: When the solders have adequately wetted the welded parts, and the solders have not wholly volatile and forms shiny pads. Separate it immediately (2 or 3 seconds for welding at each pad). If the welded surface is loss of gloss or is coarse, it indicates that the withdrawal is too late.
