ForLow-temperature tin wireDuring the usage process, there are problems such as the soldering iron tip turning black and air oxidation.Shenzhen JJYAfter analyzing the reasons, the following key points are obtained:

    Customer pairTin wireThe quality of the soldering iron tip products applied is problematic.

At present, there are several types of soldering iron tips on the sales market. One type is a round tip with electroplating process. The electroplating layer of the soldering iron tip is relatively inseparable and is not easy to be damaged. The other type is to put several thousand soldering iron tips in a blue box and flip the electroplating process.

    Therefore, the uniformity and tightness of the electroplating process layer are average, and it is prone to damage. Some customers buy some copper strips themselves, cut them and then use them, but the actual effect is relatively poor. The service life of the soldering iron tips made by different processing techniques is different, which leads to oxidation and blackening of the soldering iron tips. Among them, the soldering iron tips cut from copper strips have a shorter service life. And it seriously endangers the glossiness of spot welding itself

    It is related to the active agent in the flux.

The stronger the activity of the active agent, the stronger its etching ability. When the activity of the active agent is too strong and the flux is not mixed evenly during production, resulting in excessive concentration of the active agent part, it will harm the soldering iron tip, causing it to turn black and oxidize. Therefore, the activity of different types of active agents will be different.

    The operation steps of the customers are related. Under reliable conditions, after about five spot welds with an electric soldering iron, the tip of the soldering iron is wiped with a sponge. Or if there is no sponge, it can be wiped from the tin pile thrown out after use to avoid the flux remaining on the tip of the soldering iron for a long time and causing damage. However, at present, most customers do not do so.

    The size of the flux in the solder wire is also related. The more flux there is, the more chemical substances will remain at the soldering iron tip during the soldering process, and the more serious the harm will be. It can be appropriately reduced, but it will indirectly affect the soldering effect of the solder wire.

    For light tin, the active agent for tin strips has better activity and is more prone to corrosion. In conclusion, when encountering air oxidation and blackening of soldering iron tips, it is necessary to select the appropriate flux, adjust the flux composition appropriately, and correctly guide the customer to use reliable operation steps and apply qualified soldering iron tips. Only in this way can better practical results be achieved.
