We all know that lead-free tin bars often generate a lot of smoke during welding, and the generated smoke will have a certain impact on human health. The welding environment of the solder bar must have a good ventilation system and a system to purify the air. If not, at least each solder bar soldering station should be equipped with a small smoking fan.

During the welding of lead-free tin bars, induction training should be given to the production staff. The operation of the solder bar can only be carried out after the skill is proficient. There is also the need for employees to develop good working habits. After the solder bar welding is completed, the equipment should be placed and placed neatly to avoid various unexpected situations. Another situation is that when repairing and welding the circuit board, the operation of the solder bar must be handled by qualified technicians to prevent some accidents.

During the production of lead-free tin bars, employees are generally required to wear protective work clothes. In this way, many unexpected situations that occur when soldering lead-free tin bars can be avoided. In addition, employees are required to wear masks when using the solder bars, because the solder bars often produce undesirable phenomena such as splashing rosin and frying tin during welding. Wearing a mask can effectively prevent similar situations from happening.

The role of solder bar:

The solder bar used for manual electronic component welding is composed of tin alloy and additives. During electronic welding, the solder bar is matched with the electric soldering iron. The high-quality electric soldering iron provides stable and continuous melting heat, and the solder bar is used as a filler. The metal is added to the surface and gap of the electronic original device, and the fixed electronic original device becomes the main component of welding. The composition of the solder bar is inseparable from the quality of the solder bar, which will affect the chemical, mechanical and physical properties of the solder bar. Solder bars without additives cannot solder electronic components because they do not have wettability and expandability. The performance of the additives developed for a long time will affect the performance of the solder bar welding.

The temperature of the soldering iron tip should be adjusted first when soldering the solder bar, because the temperature of the soldering iron tip required by different types of solder bars is different, and the appropriate temperature is particularly important for the soldering of the solder bar. A suitable soldering iron tip can improve production efficiency and reduce operating temperature. The quality of the soldering iron tip is also very important when the solder bar is soldered. Generally, a soldering iron tip with good thermal properties such as heat recovery should be selected when purchasing.

After the solder bar is soldered or when the electric soldering iron is not used, the power supply should be unplugged immediately. At the same time, because the soldering iron has just been soldered, the temperature of the soldering iron for soldering the solder bar is still very high, so you must not touch the soldering part with your hands to avoid burns. . All solder bar soldering should be pre-trained. Untrained personnel are prohibited from touching all equipment for welding solder bars. In addition, when the solder bar is not welded, the electric soldering iron should be placed in a cool and dry place to facilitate the next solder bar welding.
