How to deal with the problem of excessive tin dross during the use of lead-free tin wire solder? For the hand dip furnace, the problem of excessive tin dross is not very normal, and this problem rarely occurs. The customer shows that the tin surface turns yellow or fades Purple, this situation may be that the furnace temperature deviation is too large during the operation of the customer. For example, the temperature is too high or the tin furnace has not been cleaned for too long, resulting in too much anti-oxidation loss and no effect. In this case, as long as Adding a small amount of anti-oxidant or cleaning the furnace, and then controlling the temperature of the tin furnace can be solved.
For the excessive tin slag mentioned in the wave furnace, first of all, it is necessary to distinguish whether the tin slag is normal. In general, the black powdery tin slag is normal, while the tofu-like tin slag is abnormal. The generation and reasons of tin dross are as follows:
a. It is also very important to add tin bars at the right time. The most appropriate time to add tin bars is to always keep the distance between the tin surface and the peak as short as possible.
b. Have you cleaned the tin slag frequently, so that the tin-containing tin falling from the peak can enter the furnace as soon as possible, instead of staying on the tin slag, and the heating step is uniform, which will also cause too much tin slag.
c. The purity of tin bars is also related. The wave furnace generally requires tin bars with high permanent purity, such as: 63/37, 60/40. Tin bars with many impurities will cause excessive tin dross during welding.
d. The usual cleaning of the furnace is also very important. If the furnace is not cleaned for a long time, the impurity content in the furnace is too high, which will also cause one of the reasons for excessive tin slag. It is necessary to clean the furnace regularly to change the tin, usually about every six months. Tin once.
e. The temperature of the wave furnace is generally controlled to be relatively low, generally 250 °C ± 5 °C (for 63/37 tin bars), and this temperature is the most basic temperature required by the solder during the welding process. If the temperature is too low, the tin cannot achieve a good dissolution, and it will cause excessive tin dross when it is used.
